The internal functions dealing with the audio/video buffer manager, the
blender, and the audio mixer, all receive pointers to the respective
objects. Those objects are embedded in the zynqmp_disp structure, and a
very small. Treating them as separate objects would require expanding
them with back-pointers to the zynqmp_disp in order to access fields
such as the device pointer for debug messages, and this isn't worth it.
Instead, merge those structures with the zynqmp_disp structure, and pass
the zynqmp_disp pointer to all internal functions.

When insmod zynqmp-dpsub.ko after rmmod it, system will hang with the

This is because that in zynqmp_dp_probe it tries to access some DP
registers while the DP controller is still in the reset state. When
running "rmmod zynqmp_dpsub", zynqmp_dp_reset(dp, true) in
zynqmp_dp_phy_exit is called to force the DP controller into the reset
state. Then insmod will call zynqmp_dp_probe to program the DP registers,
but at this moment the DP controller hasn't been brought out of the reset
state yet since the function zynqmp_dp_reset(dp, false) is called later and
this will result the system hang.
Releasing the reset to DP controller before any read/write operation to it
will fix this issue. And for symmetry, move zynqmp_dp_reset() call from
zynqmp_dp_phy_exit() to zynqmp_dp_remove().

The Runtime PM subsystem will force the device "fd4a0000.zynqmp-display"
to enter suspend state while booting if the following conditions are met:
- the usage counter is zero (pm_runtime_get_sync hasn't been called yet)
- no 'active' children (no zynqmp-dp-snd-xx node under dpsub node)
- no other device in the same power domain (dpdma node has no
"power-domains = <&zynqmp_firmware PD_DP>" property)
So there is a scenario as below:
1) DP device enters suspend state <- call zynqmp_gpd_power_off
2) zynqmp_disp_crtc_setup_clock <- configurate register VPLL_FRAC_CFG
3) pm_runtime_get_sync <- call zynqmp_gpd_power_on and clear previous
VPLL_FRAC_CFG configuration
4) clk_prepare_enable(disp->pclk) <- enable failed since VPLL_FRAC_CFG
configuration is corrupted
From above, we can see that pm_runtime_get_sync may clear register
VPLL_FRAC_CFG configuration and result the failure of clk enabling.
Putting pm_runtime_get_sync at the very beginning of the function
zynqmp_disp_crtc_atomic_enable can resolve this issue.

The Samsung ATNA33XC20 panel is an AMOLED eDP panel that has backlight
control over the DP AUX channel.
This panel is _almost_ able to be controlled in a "simple" way (and it
originally was implemented in panel-simple.c), but it's really
impossible to get the backlight semantics right there without adding
wacky special-case code to panel-simple. Let's give up and clone the
parts of panel-simple that we need and implement the power sequence
that this panel needs.
NOTE: we'll still leave the devicetree bindings alone. Even though the
power-sequencing is non-standard the bindings are still "simple".

Those delays were added to support the Samsung ATNA33XC20
panel. However, we've moving that to its own panel driver and out of
panel-simple. That means we don't need the ability to specify this
delay.
NOTE: it's unlikely we want to keep this delay "just in case" some
other panel needs it. The enable-gpio and the power supply are really
supposed to be different ways to specify the same thing: the main
enable of the panel. Supporting a delay between them doesn't really

This panel's power sequencing really can't be handled properly by

When testing with a panel that's apparently a little more persnickety
about the correct power sequence (specifically Samsung ATNA33XC20), we
found that the ti-sn65dsi86 was doing things just slightly wrong.
Looking closely at the ti-sn65dsi86's datasheet, the power off
sequence is supposed to be:
1. Clear VSTREAM_ENABLE bit
2. Stop DSI stream from GPU. DSI lanes must be placed in LP11 state.
3. Program the ML_TX_MODE to 0x0 (OFF)
4. Program the DP_NUM_LANES register to 0x0
5. Clear the DP_PLL_EN bit.
6. Deassert the EN pin.
7. Remove power from supply pins
Since we were doing the whole sequence in the "disable", I believe
that step #2 (stopping the DSI stream from the GPU) wasn't
happening. We also weren't setting DP_NUM_LANES to 0.
Let's fix this.
NOTE: things are a little asymmetric now. For instance, we turn the
PLL on in "enable" but now we're not turning it off until
"post_disable". It would seem to make sense to move the PLL turning on
to "pre_enable" to match. Unfortunately, I don't believe that's
allowed. It looks as if (in the non-refclk mode which probably nobody
is using) we have to wait until the MIPI clock is there before we can
enable the PLL. In any case, the way it is here won't really
hurt--it'll just leave the PLL on a little longer.

The function drm_edp_backlight_init() is defined such that the
"driver_pwm_freq_hz" parameter is optional--it's 0 if you don't want
to futz with it. If you follow this variable through, you'll find out
that if it's 0 we won't ever set the "bl->pwmgen_bit_count", leaving
it as 0.
That means that before using it in drm_edp_backlight_enable() we need
to check to see if it's non-zero.
Programming this field to zero was confusing the panel I tested with
(Samsung ATNA33XC20). The backlight still worked somewhat but the
brightness values didn't correspond to what they should have been.

The kerneldoc in drm_lease.c is unused because none of the functions
are driver interfaces as the symbols are not exported.
Since they aren't used and much of the existing comments don't provide
any insights (e.g. they just repeat the function name or list out the
function parameters), they should be removed to make them easier to
maintain and to make useful info more obvious.
As a note, many of the comments mention whether idr_mutex should be
held, but these are mostly redundant in cases where the function
contains lockdep assertions or grabs the mutex.
To simplify review, here's the reasoning behind each update.
drm_lease_owner:
function name is self-descriptive
_drm_find_lessee:
function name is self-descriptive
_drm_lease_held_master:
function name and signature are self-descriptive
_drm_has_leased:
kerneldoc is summarized into a comment because the function name could
be interpreted ambiguously (check if the object has been leased VS
check if the master has a lease on the object)
_drm_lease_held:
Retain the idr_mutex comment because the function does not directly
grab the mutex or use a lockdep assertion.
Otherwise, the function name is self-descriptive.
drm_lease_held:
function name is self-descriptive
drm_lease_filter_crtcs:
Kerneldoc is summarized into a comment because the function name could
be interpreted ambiguously (filter leases based on crtcs mask VS
filter crtcs mask based on leases)
drm_lease_create:
Kerneldoc removed.
Useful function details such as atomic leasing are retained.
Errno interpretations are useful and retained.
drm_lease_destroy:
function name is self-descriptive. Additional information is also
removed as they're already present as comments inside the function.
_drm_lease_revoke:
function name is self-descriptive
drm_lease_revoke:
function name is self-descriptive
drm_mode_create_lease_ioctl:
Kerneldoc removed, but useful function details retained.
drm_mode_list_lessees_ioctl:
function name is self-descriptive. Additional details restate what the

drm_mode_get_lease_ioctl:

The vc4_hdmi_audio_prepare function and the functions it's calling have
in several occurences multiple dereferences of either the sample rate or
the number of channels.
It turns out that these variables are also passed through the hdmi codec
parameters structure. Convert all the users to use this structure, and
if it's used multiple times use a variable to store it instead of
dereferencing it every time.

We make the following changes to the documentation of drm leases to
make it easier to reason about their usage. In particular, we clarify
the lifetime and locking rules of lease fields in drm_master:
1. Make it clear that &drm_device.mode_config.idr_mutex protects the
lease idr and list structures for drm_master. The lessor field itself
doesn't need to be protected as it doesn't change after it's set in
drm_lease_create.
2. Add descriptions for the lifetime of lessors and leases.
3. Add an overview DOC: section in drm-uapi.rst that defines the
terminology for drm leasing, and explains how leases work and why
they're used.

On platforms that support multiple backlights, register
each one separately. This lets us manage them independently
rather than registering a single backlight and applying the
same settings to both.

This converts the internal backlight in the Sony ACX424AKP
driver to do it the canonical way:
- Assign the panel->backlight during probe.
- Let the panel framework handle the backlight.
- Make the backlight .set_brightness() turn the backlight
off completely if blank.
- Fix some dev_err_probe() use cases along the way.
Tested on the U8500 HREF520 reference design.

Inside drm_is_current_master, using the outer drm_device.master_mutex
to protect reads of drm_file.master makes the function prone to creating
lock hierarchy inversions. Instead, we can use the
drm_file.master_lookup_lock that sits at the bottom of the lock
hierarchy.

We've gotten a number of reports about backlight control not
working on panels which indicate that they use aux backlight
control. A recent patch:
commit 2d73eabe29
Author: Camille Cho <Camille.Cho@amd.com>
Date: Thu Jul 8 18:28:37 2021 +0800
drm/amd/display: Only set default brightness for OLED
[Why]
We used to unconditionally set backlight path as AUX for panels capable
of backlight adjustment via DPCD in set default brightness.
[How]
This should be limited to OLED panel only since we control backlight via
PWM path for SDR mode in LCD HDR panel.

Changes some other code to only use aux for backlight control on
OLED panels. The commit message seems to indicate that PWM should
be used for SDR mode on HDR panels. Do something similar for
backlight control in general. This may need to be revisited if and
when HDR started to get used.
