Douglas Anderson 27ed2b3f22 drm/bridge: ti-sn65dsi86: Export bridge GPIOs to Linux
The ti-sn65dsi86 MIPI DSI to eDP bridge chip has 4 pins on it that can
be used as GPIOs in a system.  Each pin can be configured as input,
output, or a special function for the bridge chip.  These are:
- GPIO1: SUSPEND Input
- GPIO2: DSIA VSYNC
- GPIO3: DSIA HSYNC or VSYNC
- GPIO4: PWM

Let's expose these pins as GPIOs.  A few notes:
- Access to ti-sn65dsi86 is via i2c so we set "can_sleep".
- These pins can't be configured for IRQ.
- There are no programmable pulls or other fancy features.
- Keeping the bridge chip powered might be expensive.  The driver is
  setup such that if all used GPIOs are only inputs we'll power the
  bridge chip on just long enough to read the GPIO and then power it
  off again.  Setting a GPIO as output will keep the bridge powered.
- If someone releases a GPIO we'll implicitly switch it to an input so
  we no longer need to keep the bridge powered for it.

Because of all of the above limitations we just need to implement a
bare-bones GPIO driver.  The device tree bindings already account for
this device being a GPIO controller so we only need the driver changes
for it.

NOTE: Despite the fact that these pins are nominally muxable I don't
believe it makes sense to expose them through the pinctrl interface as
well as the GPIO interface.  The special functions are things that the
bridge chip driver itself would care about and it can just configure
the pins as needed.

Lubomir Rintel e7f12054a1 drm/bridge: chrontel-ch7033: Add a new driver
This is a driver for video encoder with VGA and DVI/HDMI outputs.

There is no documentation for the chip -- the operation was guessed from
what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names
come from the ch7035 driver in Mediatek's GPL code dump.

Only bare minimum is implemented -- no fancy stuff, such as scaling. That
would only worsen our misery. We don't load the firmware and we don't need
to even bother enabling the MCU.  There are probably no distributable
firmware images anyway.

Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60,
with VGA as well as DVI.

Arnd Bergmann 78b0d99a68 drm/bridge: fix stack usage warning on old gcc
Some older versions of gcc badly optimize code that passes
an inline function argument into another function by reference,
causing huge stack usage:

Enric Balletbo i Serra 30be303108 drm/bridge: panel: Return always an error pointer in drm_panel_bridge_add()
Since commit 89958b7cd9 ("drm/bridge: panel: Infer connector type from
panel by default"), drm_panel_bridge_add() and their variants can return
NULL and an error pointer. This is fine but none of the actual users of
the API are checking for the NULL value. Instead of change all the
users, seems reasonable to return an error pointer instead. So change
the returned value for those functions when the connector type is unknown.

Some drivers (e.g. sun4i-drm) need this info to decide whether they
need to enable dithering. Currently driver reports what panel supports

Hardcode BPC to 6 for now since that's the only BPC
that driver supports.

drm/bridge: analogix_dp: Split bind() into probe() and real bind()
Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.

Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.

This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

Jernej Skrabec 0e8003076a drm/bridge: dw-hdmi: rework csc related functions
is_color_space_conversion() is a misnomer. It checks not only if color
space conversion is needed, but also if format conversion is needed.
This is actually desired behaviour because result of this function
determines if CSC block should be enabled or not (CSC block can also do
format conversion).

In order to clear misunderstandings, let's rework
is_color_space_conversion() to do exactly what is supposed to do and add
another function which will determine if CSC block must be enabled or
not.

Icenowy Zheng 2be30d34a3 drm/bridge: analogix-anx6345: fix set of link bandwidth
Current code tries to store the link rate (in bps, which is a big
number) in a u8, which surely overflow. Then it's converted back to
bandwidth code (which is thus 0) and written to the chip.

The code sometimes works because the chip will automatically fallback to
the lowest possible DP link rate (1.62Gbps) when get the invalid value.
However, on the eDP panel of Olimex TERES-I, which wants 2.7Gbps link,
it failed.

As we had already read the link bandwidth as bandwidth code in earlier
code (to check whether it is supported), use it when setting bandwidth,
instead of converting it to link rate and then converting back.

Laurent Pinchart 0c275c3017 drm/bridge: Add bridge driver for display connectors
Display connectors are modelled in DT as a device node, but have so far
been handled manually in several bridge drivers. This resulted in
duplicate code in several bridge drivers, with slightly different (and
thus confusing) logics.

In order to fix this, implement a bridge driver for display connectors.
The driver centralises logic for the DVI, HDMI, VGAn composite and
S-video connectors and exposes corresponding bridge operations.

This driver in itself doesn't solve the issue completely, changes in
bridge and display controller drivers are needed to make use of the new
connector driver.

Laurent Pinchart a25b988ff8 drm/bridge: Extend bridge API to disable connector creation
Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:

- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.

- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.

- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).

In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).

Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.

The change is based on the following semantic patch, with manual review
and edits.

Douglas Anderson c2e1ea320d drm/bridge: ti-sn65dsi86: Train at faster rates if slower ones fail
If we fail training at a lower DP link rate let's now keep trying
until we run out of rates to try.  Basically the algorithm here is to
start at the link rate that is the theoretical minimum and then slowly
bump up until we run out of rates or hit the max rate of the sink.  We
query the sink using a DPCD read.

This is, in fact, important in practice.  Specifically at least one
panel hooked up to the bridge (AUO B116XAK01) had a theoretical min
rate more than 1.62 GHz (if run at 24 bpp) and fails to train at the
next rate (2.16 GHz).  It would train at 2.7 GHz, though.

Douglas Anderson 3438ea3dc8 drm/bridge: ti-sn65dsi86: Group DP link training bits in a function
We'll re-organize the ti_sn_bridge_enable() function a bit to group
together all the parts relating to link training and split them into a
sub-function.  This is not intended to have any functional change and
is in preparation for trying link training several times at different
rates.  One small side effect here is that if link training fails
we'll now leave the DP PLL disabled, but that seems like a sane thing
to do.

Douglas Anderson 37c1d89820 drm/bridge: ti-sn65dsi86: Use 18-bit DP if we can
The current bridge driver always forced us to use 24 bits per pixel
over the DP link.  This is a waste if you are hooked up to a panel
that only supports 6 bits per color or fewer, since in that case you
can run at 18 bits per pixel and thus end up at a lower DP clock rate.

Let's support this.

While at it, let's clean up the math in the function to avoid rounding
errors (and round in the correct direction when we have to round).
Numbers are sufficiently small (because mode->clock is in kHz) that we
don't need to worry about integer overflow.

Douglas Anderson cf33de1799 drm/bridge: ti-sn65dsi86: Config number of DP lanes Mo' Betta
The driver used to say that the value to program into bridge register
0x93 was dp_lanes - 1.  Looking at the datasheet for the bridge, this
is wrong.  The data sheet says:
* 1 = 1 lane
* 2 = 2 lanes
* 3 = 4 lanes

A more proper way to express this encoding is min(dp_lanes, 3).

At the moment this change has zero effect because we've hardcoded the
number of DP lanes to 4.  ...and (4 - 1) == min(4, 3).  How fortunate!
...but soon we'll stop hardcoding the number of lanes.

Douglas Anderson fa8a66c687 drm/bridge: ti-sn65dsi86: Don't use MIPI variables for DP link
The ti-sn65dsi86 is a bridge from MIPI to DP and thus has two links:
the MIPI link and the DP link.  The two links do not need to have the
same format or number of lanes.  Stop using MIPI variables when
talking about the DP link.

This has zero functional change because:
* currently we are hardcoding the MIPI link as unpacked RGB888 which
  requires 24 bits and currently we are not changing the DP link rate
  from the bridge's default of 8 bits per pixel.
* currently we are hardcoding both the MIPI and DP as being 4 lanes.

This is all in prep for fixing some of the above.

Tomi Valkeinen 8a6483ac63 drm/bridge: tc358767: fix poll timeouts
Link training fails with:

  Link training timeout waiting for LT_LOOPDONE!
  main link enable error: -110

This is caused by too tight timeouts, which were changed recently in
aa92213f38 ("drm/bridge: tc358767: Simplify polling in tc_link_training()").

With a quick glance, the commit does not change the timeouts. However,
the method of delaying/sleeping is different, and as the timeout in the
previous implementation was not explicit, the new version in practice
has much tighter timeout.

The same change was made to other parts in the driver, but the link
training timeout is the only one I have seen causing issues.
Nevertheless, 1 us sleep is not very sane, and the timeouts look pretty
tight, so lets fix all the timeouts.

One exception was the aux busy poll, where the poll sleep was much
longer than necessary (or optimal).

I measured the times on my setup, and now the sleep times are set to
such values that they result in multiple loops, but not too many (say,
5-10 loops). The timeouts were all increased to 100ms, which should be
more than enough for all of these, but in case of bad errors, shouldn't
stop the driver as multi-second timeouts could do.

Fabrizio Castro 319d8e9814 drm/bridge: lvds-codec: Simplify panel DT node localisation
The probe function needs to get ahold of the panel device tree
node, and it achieves that by using a combination of
of_graph_get_port_by_id, of_get_child_by_name, and
of_graph_get_remote_port_parent. We can achieve the same goal
by replacing those calls with a call to of_graph_get_remote_node
these days.

Add support for transparent LVDS decoders by adding a new
compatible string ("lvds-decoder") to the driver.
This patch also adds member connector_type to struct lvds_codec,
and that's because LVDS decoders have a different connector type
from LVDS encoders. We fill this new member up with the data
matching the compatible string.

Heiko Stuebner 89bddff6be drm/bridge/synopsys: dsi: move phy_ops callbacks around panel enablement
If implementation-specific phy_ops need to be defined they probably
should be enabled before trying to talk to the panel and disabled only
after the panel was disabled.

Right now they are enabled last and disabled first, so might make it
impossible to talk to some panels - example for this being the px30
with an external Innosilicon dphy that needs the phy to be enabled
to transfer commands to the panel.

So move the calls appropriately.

changed in v5:
- rebased on top of 5.5-rc1
- merged with dsi timing change to prevent ordering conflicts

Heiko Stuebner 25ed8aeb9c drm/bridge/synopsys: dsi: driver-specific configuration of phy timings
The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.

To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.

Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

changes in v5:
- rebase on 5.5-rc1
- merge into px30 dsi series to prevent ordering conflicts

changes in v4:
- rebase to make it directly fit on top of drm-misc-next after all

changes in v3:
- check existence of phy_ops->get_timing in __dw_mipi_dsi_probe()
- emit actual error when get_timing() call fails
- add tags from Philippe and Yannick

changes in v2:
- add driver-specific handling, don't force all bridge users to use
  the same timings, as suggested by Philippe

Sam Ravnborg 06c4a9c2ae drm/panel: decouple connector from drm_panel
To facilitate moving connector creation to display drivers,
decouple the drm_connector from drm_panel.

This patch adds a connector argument to drm_panel_get_modes().

All users of drm_panel_get_modes() already had the connector
available, so updating users was trivial.

With this patch drm_panel no longer keeps a reference to the drm_connector.

Sam Ravnborg d383fb5f8a drm: get drm_bridge_panel connector via helper
The drm_connector created by drm_panel_bridge was accessed
via drm_panel.connector.
Avoid the detour around drm_panel by providing a simple get method.
This avoids direct access to the connector field in drm_panel in
the two users.

The change is done in preparation for removal of drm_panel.connector.

Update pl111 and tve200 to use the new helper.

Linus Torvalds 99a0d9f5e8 This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
 
 - Expose pull up/down flags for the GPIO character device to
   userspace. After clear input from the RaspberryPi and Beagle
   communities, it has been established that prototyping,
   industrial automation and make communities strongly need
   this feature, and as we want people to use the character
   device, we have implemented the simple pull up/down
   interface for GPIO lines. This means we can specify that
   a (chip-specific) pull up/down resistor can be enabled,
   but does not offer fine-grained control such as cases
   where the resistance of the same pull resistor can be
   controlled (yet).
 
 - Introduce devm_fwnode_gpiod_get_index() and start to phase out
   the old symbol devm_fwnode_get_index_gpiod_from_child().
 
 - A bit of documentation clean-up work.
 
 - Introduce a define for GPIO line directions and deploy it
   in all GPIO drivers in the drivers/gpio directory.
 
 - Add a special callback to populate pin ranges when
   cooperating with the pin control subsystem and registering
   ranges as part of adding a gpiolib driver and a
   gpio_irq_chip driver at the same time. This is also
   deployed in the Intel Merrifield driver.
 
 New drivers:
 
 - RDA Micro GPIO controller.
 
 - XGS-iproc GPIO driver.
 
 Driver improvements:
 
 - Wake event and debounce support on the Tegra 186 driver.
 
 - Finalize the Aspeed SGPIO driver.
 
 - MPC8xxx uses a normal IRQ handler rather than a chained
   handler.

drm/bridge: anx6345: Fix compilation breakage on systems without CONFIG_OF

on some fields (of_node) being declared in some structures (drm_bridge).

This isn't true for all platforms, so make sure we can only compile the

drm: bridge: dw-hdmi: Report connector status using callback
Allow codec driver register callback function for plug event.

The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec

dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.

dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.

When connector plug/unplug event happens, report this event using the
callback.

Make sure that audio and drm are using the single source of truth for
connector status.

Merge v5.4-rc4 into drm-next

Thierry needs fd70c7755b ("drm/bridge: tc358767: fix max_tu_symbol
value") to be able to merge his dp_link patch series.

Some adjacent changes conflicts, plus some clashes in i915 due to
cherry-picking and git trying to be helpful and leaving both versions
in.

Daniel Kurtz fadfee3f9d drm/bridge: dw-hdmi: Restore audio when setting a mode
When setting a new display mode, dw_hdmi_setup() calls
dw_hdmi_enable_video_path(), which disables all hdmi clocks, including
the audio clock.

We should only (re-)enable the audio clock if audio was already enabled
when setting the new mode.

Without this patch, on RK3288, there will be HDMI audio on some monitors
if i2s was played to headphone when the monitor was plugged.
ACER H277HU and ASUS PB278 are two of the monitors showing this issue.

Jonas Karlman 7cea855922 drm/bridge: dw-hdmi: Add Dynamic Range and Mastering InfoFrame support
Add support for configuring Dynamic Range and Mastering InfoFrame from
the hdr_output_metadata connector property.

This patch adds a use_drm_infoframe flag to dw_hdmi_plat_data that platform
drivers use to signal when Dynamic Range and Mastering infoframes is supported.
This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version,
and only GXL support DRM InfoFrame.

These changes were based on work done by Zheng Yang <zhengyang@rock-chips.com>
to support DRM InfoFrame on the Rockchip 4.4 BSP kernel at [1] and [2]

Brian Masney 025910db80 drm/bridge: analogix-anx78xx: add support for 7808 addresses
According to the downstream Android sources, the anx7808 variants use
address 0x78 for TX_P0 and the anx781x variants use address 0x70. Since
the datasheets aren't available for these devices, and we only have the
downstream kernel sources to look at, let's assume that these addresses
are fixed based on the model, and pass the i2c addresses to the driver
via the data pointer in the driver's of_match_table.

Tomi Valkeinen fd70c7755b drm/bridge: tc358767: fix max_tu_symbol value
max_tu_symbol was programmed to TU_SIZE_RECOMMENDED - 1, which is not
what the spec says. The spec says:

roundup ((input active video bandwidth in bytes/output active video
bandwidth in bytes) * tu_size)

It is not quite clear what the above means, but calculating
max_tu_symbol = (input Bps / output Bps) * tu_size seems to work and
fixes the issues seen.

This fixes artifacts in some videomodes (e.g. 1024x768@60 on 2-lanes &
1.62Gbps was pretty bad for me).

Ronald Tschalär 710abfe8ea drm/bridge: sil_sii8620: make remote control optional.
commit d6abe6df70 ("drm/bridge: sil_sii8620: do not have a dependency
of RC_CORE") changed the driver to select both RC_CORE and INPUT.
However, this causes problems with other drivers, in particular an input
driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate
commit):

  drivers/clk/Kconfig:9:error: recursive dependency detected!
  drivers/clk/Kconfig:9:        symbol COMMON_CLK is selected by MFD_INTEL_LPSS
  drivers/mfd/Kconfig:566:      symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI
  drivers/mfd/Kconfig:580:      symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI
  drivers/input/keyboard/Kconfig:73:    symbol KEYBOARD_APPLESPI depends on INPUT
  drivers/input/Kconfig:8:      symbol INPUT is selected by DRM_SIL_SII8620
  drivers/gpu/drm/bridge/Kconfig:83:    symbol DRM_SIL_SII8620 depends on DRM_BRIDGE
  drivers/gpu/drm/bridge/Kconfig:1:     symbol DRM_BRIDGE is selected by DRM_PL111
  drivers/gpu/drm/pl111/Kconfig:1:      symbol DRM_PL111 depends on COMMON_CLK

According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts the commit.

In order to address the original reason for the commit, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).

Matthias Kaehlcke bee447e224 drm/bridge: dw-hdmi: Refuse DDC/CI transfers on the internal I2C controller
The DDC/CI protocol involves sending a multi-byte request to the
display via I2C, which is typically followed by a multi-byte
response. The internal I2C controller only allows single byte
reads/writes or reads of 8 sequential bytes, hence DDC/CI is not
supported when the internal I2C controller is used. The I2C
transfers complete without errors, however the data in the response
is garbage. Abort transfers to/from slave address 0x37 (DDC) with
-EOPNOTSUPP, to make it evident that the communication is failing.

Hans Verkuil 10d8f308ba cec: add cec_adapter to cec_notifier_cec_adap_unregister()
It is possible for one HDMI connector to have multiple CEC adapters. The
typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.

The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.

Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

When transmitting IEC60985 linear PCM audio, we configure the
Aduio Sample Channel Status information in the IEC60958 frame.
The status bit is already available in iec.status of hdmi_codec_params.

This fix the issue that audio does not come out on some monitors
(e.g. LG 22CV241)

Note that these registers are only for interfaces:
I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA
(AHBAUDDMA).
For S/PDIF interface this information comes from the stream.

Currently this function dw_hdmi_set_channel_status is only called
from dw-hdmi-i2s-audio in I2S setup.

Rob Clark 2472518e44 Revert "drm/bridge: adv7511: Attach to DSI host at probe time"
This reverts commit 83f35bc3a8.

There are at least two DSI controller drivers which relies on the old
behaviour of adv7511 driver. To avoid platform breakage this patch
should be reverted. This is a temporary solution, as it blocks adv7511
usage with other platforms.
Assumption that DSI device driver (bridge/panel) should first expose
drm_bridge/drm_panel object, then look for DSI bus is just incorrect -
it can work with devices controlled via i2c but it cannot work with
devices controlled via DSI - they will not be able to probe.
To solve the issue following steps should be performed:
- rework reverted patch allowing co-operation with broken DSI controller
  drivers - with simple/ugly workaround,
- fix controller drivers and then remove workaround.

Laurent Pinchart 89958b7cd9 drm/bridge: panel: Infer connector type from panel by default
The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().

Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

expression dev;

Boris Brezillon ee68c743f8 drm: Stop including drm_bridge.h from drm_crtc.h
We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.

Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

Geert Uytterhoeven 5ad773f9a9 drm/bridge: dumb-vga-dac: Fix dereferencing -ENODEV DDC channel
If the VGA connector has no DDC channel, an error pointer will be
dereferenced, e.g. on Salvator-XS:

    Unable to handle kernel NULL pointer dereference at virtual address 000000000000017d
    ...
    Call trace:
     sysfs_do_create_link_sd.isra.0+0x40/0x108
     sysfs_create_link+0x20/0x40
     drm_sysfs_connector_add+0xa8/0xc8
     drm_connector_register.part.3+0x54/0xb0
     drm_connector_register_all+0xb0/0xd0
     drm_modeset_register_all+0x54/0x88
     drm_dev_register+0x18c/0x1d8
     rcar_du_probe+0xe4/0x150
     ...

This happens because vga->ddc either contains a valid DDC channel
pointer, or -ENODEV, and drm_connector_init_with_ddc() expects a valid
DDC channel pointer, or NULL.

Fix this by resetting vga->ddc to NULL in case of -ENODEV, and replacing
the existing error checks by non-NULL checks.
This is similar to what the HDMI connector driver does.

Wolfram Sang af80559b4d i2c: replace i2c_new_secondary_device with an ERR_PTR variant
In the general move to have i2c_new_*_device functions which return
ERR_PTR instead of NULL, this patch converts i2c_new_secondary_device().

There are only few users, so this patch converts the I2C core and all
users in one go. The function gets renamed to i2c_new_ancillary_device()
so out-of-tree users will get a build failure to understand they need to
adapt their error checking code.

Sean Paul 6c836d965b drm/rockchip: Use the helpers for PSR
Instead of rolling our own implementation for tracking when PSR should
be [in]active, use the new self refresh helpers to do the heavy lifting.

Changes in v2:
- updated to reflect changes made in the helpers
Changes in v3:
- use the new atomic hooks to inspect crtc state instead of needing conn state (Daniel)
Changes in v4:
- Use Laurent's get_new_connector_for_encoder helper (Daniel)
- Exit vop disable early if it's already off
Changes in v5:
- Rebase on latest drm-misc-next
- Resolve conflict with s/edp_vsc_psr/dp_sdp/ rename
- Resolve conflict with drm_atomic.h header inclusion

Rob Clark 67b587934c drm/bridge: ti-sn65dsi86: correct dsi mode_flags
Noticed while comparing register dump of how bootloader configures DSI
vs how kernel configures.  It seems the bridge still works either way,
but fixing this clears the 'CHA_DATATYPE_ERR' error status bit.

Neil Armstrong fdbdcc83ff drm/bridge: dw-hdmi: Use automatic CTS generation mode when using non-AHB audio
When using an I2S source using a different clock source (usually the I2S
audio HW uses dedicated PLLs, different from the HDMI PHY PLL), fixed
CTS values will cause some frequent audio drop-out and glitches as
reported on Amlogic, Allwinner and Rockchip SoCs setups.

Setting the CTS in automatic mode will let the HDMI controller generate
automatically the CTS value to match the input audio clock.

The DesignWare DW-HDMI User Guide explains:
  For Automatic CTS generation
  Write "0" on the bit field "CTS_manual", Register 0x3205: AUD_CTS3

The DesignWare DW-HDMI Databook explains :
  If "CTS_manual" bit equals 0b this registers contains "audCTS[19:0]"
  generated by the Cycle time counter according to specified timing.

Lucas Stach 52c2197aae drm/bridge: tc358767: do a software reset if reset pin isn't connected
To get the chip into the expected state, even when the hardware reset pin
isn't connected, do a software reset in this case. It isn't as thorough as
the hardware reset, as the I2C communication block can not be reset for
obvious reasons, but it's getting the chip into a defined state.

Matt Redfearn 83f35bc3a8 drm/bridge: adv7511: Attach to DSI host at probe time
In contrast to all of the DSI panel drivers in drivers/gpu/drm/panel
which attach to the DSI host via mipi_dsi_attach() at probe time, the
ADV7533 bridge device does not. Instead it defers this to the point that
the upstream device connects to its bridge via drm_bridge_attach().
The generic Synopsys MIPI DSI host driver does not register it's own
drm_bridge until the MIPI DSI has attached. But it does not call
drm_bridge_attach() on the downstream device until the upstream device
has attached. This leads to a chicken and the egg failure and the DRM
pipeline does not complete.
Since all other mipi_dsi_device drivers call mipi_dsi_attach() in
probe(), make the adv7533 mipi_dsi_device do the same. This ensures that
the Synopsys MIPI DSI host registers it's bridge such that it is
available for the upstream device to connect to.

Andrey Smirnov e0655feaec drm/bridge: tc358767: Increase AUX transfer length limit
According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.

Andrey Smirnov 792a081a1b drm/bridge: tc358767: Simplify AUX data write
Simplify AUX data write by dropping index arithmetic and shifting and
replacing it with a call to a helper function that does two things:

    1. Copies user-provided data into a write buffer
    2. Transfers contents of the write buffer to up to 4 32-bit
       registers on the chip

Note that separate data endianness fix:

    tmp = (tmp << 8) | buf[i];

that was reserved for DP_AUX_I2C_WRITE looks really strange, since it
will place data differently depending on the passed user-data
size. E.g. for a write of 1 byte, data transferred to the chip would
look like:

[byte0] [dummy1] [dummy2] [dummy3]

whereas for a write of 4 bytes we'd get:

[byte3] [byte2] [byte1] [byte0]

Since there's no indication in the datasheet that I2C write buffer
should be treated differently than AUX write buffer and no comment in
the original code explaining why it was done this way, that special
I2C write buffer transformation was dropped in this patch.

Andrey Smirnov 6d0c383159 drm/bridge: tc358767: Drop custom tc_write()/tc_read() accessors
A very unfortunate aspect of tc_write()/tc_read() macro helpers is
that they capture quite a bit of context around them and thus require
the caller to have magic variables 'ret' and 'tc' as well as label
'err'. That makes a number of code paths rather counter-intuitive and
somewhat clunky, for example tc_stream_clock_calc() ends up being like
this:

	int ret;

	tc_write(DP0_VIDMNGEN1, 32768);

	return 0;
err:
	return ret;

which is rather surprising when you read the code for the first
time. Since those helpers arguably aren't really saving that much code
and there's no way of fixing them without making them too verbose to
be worth it change the driver code to not use them at all.

We use delayed_work in HPD handling, and cancel any scheduled work in
tfp410_fini using cancel_delayed_work_sync(). However, we have only
initialized the delayed work if we actually have a HPD interrupt
configured in the DT, but in the tfp410_fini, we always cancel the work,
possibly causing a WARN().

Fix this by doing the cancel only if we actually had the delayed work
set up.

Douglas Anderson 99d02ed523 drm: bridge: dw-hdmi: Add hook for resume
On Rockchip rk3288-based Chromebooks when you do a suspend/resume
cycle:

1. You lose the ability to detect an HDMI device being plugged in.

2. If you're using the i2c bus built in to dw_hdmi then it stops
working.

Let's add a hook to the core dw-hdmi driver so that we can call it in
dw_hdmi-rockchip in the next commit.

NOTE: the exact set of steps I've done here in resume come from
looking at the normal dw_hdmi init sequence in upstream Linux plus the
sequence that we did in downstream Chrome OS 3.14.  Testing show that
it seems to work, but if an extra step is needed or something here is
not needed we could improve it.

As part of this change we'll refactor the hardware init bits of
dw-hdmi to happen all in one function and all at the same time.  Since
we need to init the interrupt mutes before we request the IRQ, this
means moving the hardware init earlier in the function, but there
should be no problems with that.  Also as part of this we now
unconditionally init the "i2c" parts of dw-hdmi, but again that ought
to be fine.

In commit 50f9495efe ("drm/bridge/synopsys: dw-hdmi: Add "unwedge"

"unwedge" pinctrl state even though on most flows through the driver
the unwedge state will just be NULL.

Fix it so that we consistently use NULL for no unwedge state.

Douglas Anderson 50f9495efe drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc bus
See the PhD thesis in the comments in this patch for details, but to
summarize this adds a hacky "unwedge" feature to the dw_hdmi i2c bus to
workaround what appears to be a hardware errata.  This relies on a
pinctrl entry to help change around muxing to perform the unwedge.

NOTE that the specific TV this was tested on was the "Samsung
UN40HU6950FXZA" and the specific port was the "STB" port.

Tomi Valkeinen 0776a269d7 drm/bridge: tc358767: use more reliable seq when finishing LT
At the end of the link training, two steps have to be taken: 1)
tc358767's LT mode is disabled by a write to DP0_SRCCTRL, and 2) Remove
LT flag in DPCD 0x102.

Toshiba's documentation tells to first write the DPCD, then modify
DP0_SRCCTRL. In my testing this often causes issues, and the link
disconnects right after those steps.

If I reverse the steps, it works every time. There's a chance that this
is DP sink specific, though, but as my testing shows this sequence to be
much more reliable, let's change it.

Link training will sometimes fail if the DP link is enabled when

disabled when the DP output is disabled, and we never enable the DP
without first disabling it, so this should never happen.

However, as the HW behavior seems to be somewhat random if DP link has

Tomi Valkeinen bfb6e014c4 drm/bridge: tc358767: fix tc_aux_get_status error handling
tc_aux_get_status() does not report AUX_TIMEOUT correctly, as it only
checks the AUX_TIMEOUT if aux is still busy. Fix this by always checking
for AUX_TIMEOUT.

Gwan-gyeong Mun 4d432f956d drm: Rename struct edp_vsc_psr to struct dp_sdp
VSC SDP Payload for PSR is one of data block type of SDP (Secondaray Data
Packet). In order to generalize SDP packet structure name, it renames
struct edp_vsc_psr to struct dp_sdp. And each SDP data blocks have
different usages, each SDP type has different reserved data blocks and
Video_Stream_Configuration Extension VESA SDP might use all of Data Blocks
as Extended INFORFRAME Data Byte. so it makes Data Block variables as
array type. And it adds comments of details of DB of VSC SDP Payload
for Pixel Encoding/Colorimetry Format. This comments follows DP 1.4a spec,
section 2.2.5.7.5, chapter "VSC SDP Payload for Pixel Encoding/Colorimetry
Format".

v7: Addressed review comments from Ville.

v9: Rename a member value name DB to db on struct dp_sdp [Laurent]

Matt Redfearn 67793bd3b3 drm/bridge: adv7511: Fix low refresh rate selection
The driver currently sets register 0xfb (Low Refresh Rate) based on the
value of mode->vrefresh. Firstly, this field is specified to be in Hz,
but the magic numbers used by the code are Hz * 1000. This essentially
leads to the low refresh rate always being set to 0x01, since the
vrefresh value will always be less than 24000. Fix the magic numbers to
be in Hz.
Secondly, according to the comment in drm_modes.h, the field is not
supposed to be used in a functional way anyway. Instead, use the helper
function drm_mode_vrefresh().

Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

  Summary:

  uapi changes:
   - Colorspace connector property
   - fourcc - new YUV formts
   - timeline sync objects initially merged
   - expose FB_DAMAGE_CLIPS to atomic userspace

   - dma_buf fence chain support
   - 64-bit dma-fence seqno comparison fixes
   - move initial fb config code to core
   - gem fence array helpers for Lima
   - ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
   - lease fixes

  ttm:
   - unified DRM_FILE_PAGE_OFFSET handling
   - Account for kernel allocations in kernel zone only

  panel:
   - OSD070T1718-19TS panel support

hdmi->i2c may not be set when ddc-i2c-bus property is used in device tree.
Fix this by using hdmi->ddc as the i2c adapter when calling drm_scdc_*().
Also report that SCDC is not supported when there is no DDC bus.
