While adding SiI9022A support to the iwg23s board, it came
up that when the HDMI transmitter is in pass through mode the
device is not compliant with the I2C specification anymore,
as it requires a far bigger tbuf, due to a delay the HDMI
transmitter is adding when relaying the STOP condition on the
monitor i2c side of things.
When not providing an appropriate delay after the STOP condition
the i2c bus would get stuck. Also, any other traffic on the bus
while talking to the monitor may cause the transaction to fail
or even cause issues with the i2c bus as well.
I2c-gates seemed to reach consent as a possible way to address
these issues, and as such this patch is implementing a solution
based on that. Since others are clearly relying on the current
implementation of the driver, this patch won't require any DT
changes.
Since we don't want any interference during the DDC Bus
Request/Grant procedure and while talking to the monitor, we
have to use the adapter locking primitives rather than the
i2c-mux locking primitives.

With the regular means of adding the dsi-component in probe it creates
a race condition with the panel probing, as the panel device only gets
created after the dsi-bus got created.
When the panel-driver is build as a module it currently fails hard as the
panel cannot be probed directly:
dw_mipi_dsi_bind()
__dw_mipi_dsi_probe()
creates dsi bus
creates panel device
triggers panel module load
panel not probed (module not loaded or panel probe slow)
drm_bridge_attach
fails with -EINVAL due to empty panel_bridge
Additionally the panel probing can run concurrently with dsi bringup
making it possible that the panel can already be found but dsi-attach
hasn't finished running.
To solve that cleanly we may want to only create the component after
the panel has finished probing, by calling component_add from the
host-attach dsi callback.
As that is specific to glue drivers, add a new struct for host_ops
so that glue drivers can tell the bridge to call specific functions
after the common host-attach and before the common host-detach run.

__dw_mipi_dsi_probe() does all the grabbing of resources and does it using
devm-helpers. So this is happening on each try of master bringup possibly
slowing down things a lot.
Drivers using the component framework may instead want to call
dw_mipi_dsi_probe separately in their probe function to setup resources
early. That way the dsi bus also gets created earlier and also not
recreated on each bind-try, so that attached panels can load their modules
and be probed way before the bridge-attach in the bind call.
So drop the call to __dw_mipi_dsi_probe and modify the function to take
a struct dw_mipi_dsi instead of the platform-device.

Let's solve the mystery of commit bf1178c989 ("drm/bridge:
ti-sn65dsi86: Add mystery delay to enable()"). Specifically the
reason we needed that mystery delay is that we weren't paying
attention to HPD.
Looking at the datasheet for the same panel that was tested for the
original commit, I see there's a timing "t3" that times from power on
to the aux channel being operational. This time is specced as 0 - 200
ms. The datasheet says that the aux channel is operational at exactly
the same time that HPD is asserted.
Scoping the signals on this board showed that HPD was asserted 84 ms
after power was asserted. That very closely matches the magic 70 ms
delay that we had. ...and actually, in my testing the 70 ms wasn't
quite enough of a delay and some percentage of the time the display
didn't come up until I bumped it to 100 ms (presumably 84 ms would
have worked too).
To solve this, we tried to hook up the HPD signal in the bridge.
...but in doing so we found that that the bridge didn't report that
HPD was asserted until ~280 ms after we powered it (!). This is
explained by looking at the sn65dsi86 datasheet section "8.4.5.1 HPD
(Hot Plug/Unplug Detection)". Reading there we see that the bridge
isn't even intended to report HPD until 100 ms after it's asserted.
...but that would have left us at 184 ms. The extra 100 ms
(presumably) comes from this part in the datasheet:
> The HPD state machine operates off an internal ring oscillator. The
> ring oscillator frequency will vary [ ... ]. The min/max range in
> the HPD State Diagram refers to the possible times based off
> variation in the ring oscillator frequency.
Given that the 280 ms we'll end up delaying if we hook up HPD is
_slower_ than the 200 ms we could just hardcode, for now we'll solve
the problem by just hardcoding a 200 ms delay in the panel driver
using the patch in this series ("drm/panel: simple: Support panels
with HPD where HPD isn't connected").
If we later find a panel that needs to use this bridge where we need
HPD then we'll have to come up with some new code to handle it. Given
the silly debouncing in the bridge chip, though, it seems unlikely.
One last note is that I tried to solve this through another way: In
ti_sn_bridge_enable() I tried to use various combinations of
dp_dpcd_writeb() and dp_dpcd_readb() to detect when the aux channel
was up. In theory that would let me detect _exactly_ when I could
continue and do link training. Unfortunately even if I did an aux
transfer w/out waiting I couldn't see any errors. Possibly I could
keep looping over link training until it came back with success, but
that seemed a little overly hacky to me.

One example are the Rockchip rk3228 and rk3328 socs that use a separate

This patch adds a 70ms mystery delay to the bridge driver in enable.
By experimentation, it seems like it can go anywhere up until we
initiate semi-auto link training. If we don't have the delay, link
training fails.
I tried to root cause this as best I could, but neither the datasheet
for the panel nor the bridge mention a delay of this magnitude in their
timing requirements. So for now, add the mystery delay until someone
figures out a better fix.

Add support for TI's sn65dsi86 dsi2edp bridge chip.
The chip converts DSI transmitted signal to eDP signal,
which is fed to the connected eDP panel.
This chip can be controlled via either i2c interface or
dsi interface. Currently in driver all the control registers
are being accessed through i2c interface only.
Also as of now HPD support has not been added to bridge
chip driver.
Changes in v1:
- Split the dt-bindings and the driver support into separate patches
(Andrzej Hajda).
- Use of gpiod APIs to parse and configure gpios instead of obsolete ones
(Andrzej Hajda).
- Use macros to define the register offsets (Andrzej Hajda).
Changes in v2:
- Separate out edp panel specific HW resource handling from bridge
driver and create a separate edp panel drivers to handle panel
specific mode information and HW resources (Sean Paul).
- Replace pr_* APIs to DRM_* APIs to log error or debug information
(Sean Paul).
- Remove some of the unnecessary structure/variable from driver (Sean
Paul).
- Rename the function and structure prefix "sn65dsi86" to "ti_sn_bridge"
(Sean Paul / Rob Herring).
- Remove most of the hard-coding and modified the bridge init sequence
based on current mode (Sean Paul).
- Remove the existing function to retrieve the EDID data and
implemented this as an i2c_adapter and use drm_get_edid() (Sean Paul).
- Remove the dummy irq handler implementation, will add back the
proper irq handling later (Sean Paul).
- Capture the required enable gpios in a single array based on dt entry
instead of having individual descriptor for each gpio (Sean Paul).
Changes in v3:
- Remove usage of irq_gpio and replace it as "interrupts" property (Rob
Herring).
- Remove the unnecessary header file inclusions (Sean Paul).
- Rearrange the header files in alphabetical order (Sean Paul).
- Use regmap interface to perform i2c transactions.
- Update Copyright/License field and address other review comments
(Jordan Crouse).
Changes in v4:
- Update License/Copyright (Sean Paul).
- Add Kconfig and Makefile changes (Sean Paul).
- Drop i2c gpio handling from this bridge driver, since i2c sda/scl gpios
will be handled by i2c master.
- Update required supplies names.
- Remove unnecessary goto statements (Sean Paul).
- Add mutex lock to power_ctrl API to avoid race conditions (Sean
Paul).
- Add support to parse reference clk frequency from dt(optional).
- Update the bridge chip enable/disable sequence.
Changes in v5:
- Fixed Kbuild test service reported warnings.
Changes in v6:
- Use PM runtime based ref-counting instead of local ref_count mechanism
(Stephen Boyd).
- Clean up some debug logs and indentations (Sean Paul).
- Simplify dp rate calculation (Sean Paul).
- Add support to configure refclk based on input REFCLK pin or DACP/N
pin (Stephen Boyd).
Changes in v7:
- Use static supply entries instead of dynamic allocation (Andrzej
Hajda).
- Defer bridge driver probe if panel is not probed (Andrzej Hajda).
- Update of_graph APIs for correct node reference management. (Andrzej
Hajda).
- Remove local display_mode object (Andrzej Hajda).
- Remove version id check function from driver.
Changes in v8:
- Move dsi register/attach function to bridge driver probe (Andrzej
Hajda).
- Introduce a new helper function to write 16bit words into consecutive
registers (Andrzej Hajda).
- Remove unnecessary macros (Andrzej Hajda).
Changes in v9:
- Remove dsi register/attach from bridge probe, since dsi dev register
completion also waits for any panel or bridge to get added. This creates
deadlock situation when bridge driver calls dsi dev register and
attach before bridge add, in its probe function.
- Fix issues faced during testing of bridge driver on actual HW.
- Remove unnecessary initializations (Stephen Boyd).
- Use local refclk lut size instead of global macro (Sean Paul).
Changes in v10:
- Use refclk to determine if continuous dsi clock is needed or not.
Changes in v11:
- Read DPPLL_SRC register to determine continuous clock instead of
using refclk handle (Stephen Boyd).
Changes in v12:
- Explain in comment as in why dsi dev registration is done in
bridge_attach (Andrzej Hajda).
- Move HPD disable to bridge_pre_enable (Andrzej Hajda).
- Make panel/DDC exclusive until HPD support is added (Andrzej Hajda).
Changes in v13:
- eDP panels report EDID via DP-AUX channel, so remove support for
dedicated DDC line (Andrzej Hajda).
Changes in v14:
- Remove unnecessary drm_panel checks (Andrzej Hajda).

Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.
Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".
Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

Current implementation does not guarantee packed pixel modes working
with every dongle. There are some dongles, which require selecting
the output mode explicitly.
Write proper values to registers in packed_pixel mode, based on how it
is done in vendor's code. Select output color space: RGB
(no packed pixel) or YCBCR422 (packed pixel).

Currently AVI infoframe is sent only in MHL3. However, some MHL2 dongles
need AVI infoframe to work correctly in either packed pixel mode or
non-packed pixel mode.
Send AVI infoframe in set_infoframes() in every case. Create an
infoframe using drm_hdmi_infoframe_from_display_mode() instead of
manually filling each infoframe structure's field.
