[WHY & HOW]
Cursor corruption observed on USBC display with specific system setup with a
reboot. Cursor memory might still in the lightsleep state due to voltage
issue, we need program DISPCLK_R_GATE_DISABLE to avoid this issue only on
DCN35.

[Why&How]
vblank immediate disable currently does not work for all asics. On
DCN401, the vblank interrupts never stop coming, and hence we never
get a chance to trigger idle optimizations.
Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

drm_sched_job_init() has no control over how users allocate struct
drm_sched_job. Unfortunately, the function can also not set some struct
members such as job->sched.
This could theoretically lead to UB by users dereferencing the struct's
pointer members too early.
It is easier to debug such issues if these pointers are initialized to
NULL, so dereferencing them causes a NULL pointer exception.
Accordingly, drm_sched_entity_init() does precisely that and initializes
its struct with memset().
Initialize parameter "job" to 0 in drm_sched_job_init().

OVL_CON_CLRFMT_MAN is a configuration for extending color format
settings of DISP_REG_OVL_CON(n).
It will change some of the original color format settings.
Take the settings of (3 << 12) for example.
- If OVL_CON_CLRFMT_MAN = 0 means OVL_CON_CLRFMT_RGBA8888.
- If OVL_CON_CLRFMT_MAN = 1 means OVL_CON_CLRFMT_PARGB8888.
Since previous SoCs did not support OVL_CON_CLRFMT_MAN, this means
that the SoC does not support the premultiplied color format.
It will break the original color format setting of MT8173.
Therefore, the blend_modes is added to the driver data and then
mtk_ovl_fmt_convert() will check the blend_modes to see if
pre-multiplied is supported in the current platform.
If it is not supported, use coverage mode to set it to the supported
color formats to solve the degradation problem.

OVL_CON_AEN is for alpha blending enable.
For the SoC that is supported the blend_modes, OVL_CON_AEN will always
enabled to use constant alpha and then use the ignore_pixel_alpha bit
to do the alpha blending for XRGB8888 format.
Note that ignore pixel alpha bit is not supported if the SoC is not
supported the blend_modes.
So it will break the original setting of XRGB8888 format for the
blend_modes unsupported SoCs, such as MT8173.
To fix the downgrade issue, enable alpha blending only when a valid
blend_mode or has_alpha is set.

we see an issue where resets fails because the engine resumes
from an incorrect RING_HEAD. Since the RING_HEAD doesn't point
to the remaining requests to re-run, but may instead point into
the uninitialised portion of the ring, the GPU may be then fed
invalid instructions from a privileged context, oft pushing the
GPU into an unrecoverable hang.
If at first the write doesn't succeed, try, try again.

The lite restore is a performance improvement feature which avoids
unnecessary context switch (flush, save and restore) if the incoming
context has a ContextID matching that of the outgoing context. The
scheduling is done by the GuC firmware, so on the driver side it's
just a matter of setting corresponding GUC_CTL_FEATURE flag.
This is supposed to be enabled by default, thus the flag is set

for_each_endpoint_of_node() requires a call to of_node_put() for every
early exit. A new error path was added to the loop without observing
this requirement.
Add the missing call to of_node_put() in the error path.

The assignment of the of_node to the aux bridge needs to mark the
of_node as reused as well, otherwise resource providers like pinctrl will
report a gpio as already requested by a different device when both pinconf
and gpios property are present.
Fix that by using the device_set_of_node_from_dev() helper instead.

Introduce a bus-width property to define the number of parallel RGB
input pins connected to the transmitter. The input bus formats are updated
accordingly. If the property is not specified, default to 24-bit bus-width.

"data-lines" property is way too similar to "data-lanes". It is also
duplicating "bus-width" from video-interfaces.yaml schema. "data-lines"
was deprecated in the bindings and "bus-width" is preferred, so parse it
instead while keeping things backwards compatible.

It is impossible to add each and every possible DDP path combination
for each and every possible combination of SoC and board: right now,
this driver hardcodes configuration for 10 SoCs and this is going to
grow larger and larger, and with new hacks like the introduction of
mtk_drm_route which is anyway not enough for all final routes as the
DSI cannot be connected to MERGE if it's not a dual-DSI, or enabling
DSC preventively doesn't work if the display doesn't support it, or
others.
Since practically all display IPs in MediaTek SoCs support being
interconnected with different instances of other, or the same, IPs
or with different IPs and in different combinations, the final DDP
pipeline is effectively a board specific configuration.
Implement OF graphs support to the mediatek-drm drivers, allowing to
stop hardcoding the paths, and preventing this driver to get a huge
amount of arrays for each board and SoC combination, also paving the
way to share the same mtk_mmsys_driver_data between multiple SoCs,
making it more straightforward to add support for new chips.
Note that the OVL_ADAPTOR software component driver needs relatively
big changes in order to fully support OF Graphs (and more SoCs anyway)
and such changes will come at a later time.
As of now, the mtk_disp_ovl_adaptor driver takes the MERGE components
(for example, on mt8195, merge 1 to 4) dynamically so, even though
later updates to the ovl-adaptor driver will *not* require bindings
changes, the merge1-4 will be temporarily omitted in the graph for the
MT8195 SoC.
This means that an example graph for this SoC looks like:
mdp_rdma (0 ~ 7) -> padding (0 ~ 7) -> ethdr -> merge5
and the resulting path in this driver will be `ovl_adaptor -> merge5`
Later updates to the ovl adaptor will expand it to support more SoCs
and, in turn, to also fully support graphs.
