ee8287e068 drm/amd/display: Fix cursor issues with ODMs and HW rotations
[WHY & HOW]
Current code for cursor positions does not work properly
with different ODM options and HW rotations like ODM
2to1, 3to1 and 4to1, and has different issues depending on
angle of HW rotations.

[HOW]
Fixed these issues so to work properly when ODM is used with HW rotations.

c6dfe8f20b drm/amd/display: Remove unnecessary variable
[WHY]
Coverity analysis flagged this code as DEADCODE because
the condition '(!need_recovery)' is never true.

The variable 'need_recovery' is initialized as 'true',
is not assigned to 'false' anywhere before the
conditional statement.

Since the variable is only used for the conditional check,
but the check can never be true, the variable itself is
redundant.

[HOW]
Removed the variable 'need_recovery'.

4fa0046f11 drm/amd/display: Remove redundant var from display_rq_dig_calc in dml
[WHY]
Coverity analysis flagged these files as containing DEADCODE, i. e.
redundant or unreachabale. In these files, variable 'mode_422' is
always the same file (0 or false), so any code logic with it is
redundant.

[HOW]
Removed 'mode_422' variable and all code with it from
'display_rq_dlg_calc_' functions in dml.

8aa5aff2bf drm/amd/display: Refactor dccg401_get_other_enable_symclk_fe
[WHY]
Function was used to check the number of FEs connected to the current BE.
This was then used to determine if the symclk could be disabled, if all
FEs were disconnected. However, the function would skip over the primary
FE and return 0 when the primary FE was still connected. This caused black
screens on driver disable with an MST daisy chain hooked up.

[HOW]
Refactored the function to correctly return the number of FEs connected to
the input BE. Also renamed it for clarity.

20fb7ca6bf drm/mediatek: Call drm_atomic_helper_shutdown() at shutdown time
Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.

This driver users the component model and shutdown happens in the base
driver. The "drvdata" for this driver will always be valid if
shutdown() is called and as of commit 2a07396828
("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop")
we don't need to confirm that "drm" is non-NULL.

a9422ec92a drm/i915/dsb: Try to document that DSB_STATUS bit 16 is level triggered
DSB_STATUS bit 16 is supposed to be a sticky bit informing us whether
the DSB was idle or not when the pipe's delayed vblank (when double
buffered registers latch) occurred. Unfortunately it turns out this
is a level triggred signal, ie. the bit will be set whenever the
DSB is busy during the scanline window between start of delayed
vblank and vtotal. Try to document that fact by renaming the bit.

Sadly this also thwarts my plan to use this bit to sanity check
that the (to be introduced) DSB based vblank evasion did its job
correctly. That would require an edge triggered signal instead.
So looks like we'll have to rely mostly on luck instead :(

dcbaaa239d drm/bridge: analogix_dp: remove clk handling from analogix_dp_set_bridge
The clock is already managed by runtime PM, which is properly invoked
from the analogix_dp_set_bridge function, so there is no need for an
additional reference.

f37952339c drm/bridge: analogix_dp: handle clock via runtime PM
There is no reason to enable the controller clock in driver probe, as
there is no HW initialization done in this function. Instead rely on
either runtime PM to handle the controller clock or statically enable
it in the driver bind routine, after which real hardware access is
required to work.

54be78446d drm/panic: Restrict graphical logo handling to built-in
When CONFIG_DRM_PANIC=y, but CONFIG_DRM=m:

    ld: drivers/gpu/drm/drm_panic.o: in function `drm_panic_setup_logo':
    drivers/gpu/drm/drm_panic.c:99: multiple definition of `init_module'; drivers/gpu/drm/drm_drv.o:drivers/gpu/drm/drm_drv.c:1079: first defined here

Fix this by restricting the graphical logo handling and its
device_initcall() to the built-in case.  Logos are freed during late
kernel initialization, so they are no longer available at module load
time anyway.

circular references in the modular case.  Hence drop the selection of
DRM_KMS_HELPER.  It was unused anyway, as v10 switched from using
the DRM format helpers to its own color format conversion, cfr. commit

9c433c87e8 drm/bridge: tc358767: Set LSCLK divider for SYSCLK to 1
The only information in the datasheet regarding this divider is a note
in SYS_PLLPARAM register documentation which states that when LSCLK is
270 MHz, LSCLK_DIV should be 1. What should LSCLK_DIV be set to when
LSCLK is 162 MHz (for DP 1.62G mode) is unclear, but empirical test
confirms using LSCLK_DIV 1 has no adverse effects either. In the worst
case, the internal TC358767 clock would run faster.

3f13e53bcf drm/bridge: tc358767: Drop line_pixel_subtract
This line_pixel_subtract is no longer needed now that the bridge can
request and obtain specific pixel clock on input to the bridge, with
clock frequency that matches the Pixel PLL frequency.

The line_pixel_subtract is now always 0, so drop it entirely.

The line_pixel_subtract was not reliable as it never worked when the
Pixel PLL and input clock were off just so that the required amount
of pixels to subtract would not be whole integer.

The precise input frequency that matches the Pixel PLL frequency is

Split tc_pxl_pll_en() into tc_pxl_pll_calc() which does only Pixel PLL
parameter calculation and tc_pxl_pll_en() which calls tc_pxl_pll_calc()
and then configures the Pixel PLL register.

This is a preparatory patch for further rework, where tc_pxl_pll_calc()
will also be used to find out the exact clock frequency generated by the
Pixel PLL. This frequency will be used as adjusted_mode clock frequency
and passed down the display pipeline to obtain exactly this frequency
on input into this bridge.

The precise input frequency that matches the Pixel PLL frequency is
important for this bridge, as if the frequencies do not match, the
