Backmerging to get the latest fixes from drm-next; specifically the
build fix from the patchset at [1]. Also fixes the build by removing
an unused variable from rzg2l_du_vsp_atomic_flush().

Replace <linux/fb.h> with a forward declaration in <asm/backlight.h> to
resolve an unnecessary dependency. Remove pmac_backlight_curve_lookup()
and struct fb_info from source and header files. The function and the
framebuffer struct are unused. No functional changes.

The hwdb selection logic as a feature that allows it to mark some fields
as 'don't care'. If we match with such a field we memcpy(..)
the current etnaviv_chip_identity into ident.
This step can overwrite some id values read from the GPU with the
'don't care' value.
Fix this issue by restoring the affected values after the memcpy(..).
As this is crucial for user space to know when this feature works as
expected increment the minor version too.

For a given bridge pipeline if any bridge sets pre_enable_prev_first
flag then the pre_enable for the previous bridge will be called before
pre_enable of this bridge and opposite is done for post_disable.
These are the potential bridge flags to alter bridge init order in order
to satisfy the MIPI DSI host and downstream panel or bridge to function.
However the existing pre_enable_prev_first logic with associated bridge
ordering has broken for both pre_enable and post_disable calls.
[pre_enable]
The altered bridge ordering has failed if two consecutive bridges on a
given pipeline enables the pre_enable_prev_first flag.
Example:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
In this example, Bridge 4 and Bridge 5 have pre_enable_prev_first.
The logic looks for a bridge which enabled pre_enable_prev_first flag
on each iteration and assigned the previou bridge to limit pointer
if the bridge doesn't enable pre_enable_prev_first flags.
If control found Bridge 2 is pre_enable_prev_first then the iteration
looks for Bridge 3 and found it is not pre_enable_prev_first and assigns
it's previous Bridge 4 to limit pointer and calls pre_enable of Bridge 3
and Bridge 2 and assign iter pointer with limit which is Bridge 4.
Here is the actual problem, for the next iteration control look for
Bridge 5 instead of Bridge 4 has iter pointer in previous iteration
moved to Bridge 4 so this iteration skips the Bridge 4. The iteration
found Bridge 6 doesn't pre_enable_prev_first flags so the limit assigned
to Encoder. From next iteration Encoder skips as it is the last bridge
for reverse order pipeline.
So, the resulting pre_enable bridge order would be,
- Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5.
This patch fixes this by assigning limit to next pointer instead of
previous bridge since the iteration always looks for bridge that does
NOT request prev so assigning next makes sure the last bridge on a
given iteration what exactly the limit bridge is.
So, the resulting pre_enable bridge order with fix would be,
- Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5, Bridge 4,
Encoder.
[post_disable]
The altered bridge ordering has failed if two consecutive bridges on a
given pipeline enables the pre_enable_prev_first flag.
Example:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
In this example Bridge 5 and Bridge 4 have pre_enable_prev_first.
The logic looks for a bridge which enabled pre_enable_prev_first flags
on each iteration and assigned the previou bridge to next and next to
limit pointer if the bridge does enable pre_enable_prev_first flag.
If control starts from Bridge 6 then it found next Bridge 5 is
pre_enable_prev_first and immediately the next assigned to previous
Bridge 6 and limit assignments to next Bridge 6 and call post_enable
of Bridge 6 even though the next consecutive Bridge 5 is enabled with
pre_enable_prev_first. This clearly misses the logic to find the state
of next conducive bridge as everytime the next and limit assigns
previous bridge if given bridge enabled pre_enable_prev_first.
So, the resulting post_disable bridge order would be,
- Encoder, Bridge 6, Bridge 5, Bridge 4, Bridge 3, Bridge 2, Bridge 1,
Panel.
This patch fixes this by assigning next with previou bridge only if the
bridge doesn't enable pre_enable_prev_first flag and the next further
assign it to limit. This way we can find the bridge that NOT requested
prev to disable last.
So, the resulting pre_enable bridge order with fix would be,
- Encoder, Bridge 4, Bridge 5, Bridge 6, Bridge 2, Bridge 3, Bridge 1,
Panel.

This function does not build on 32-bit targets when the compiler
fails to reduce DIV_ROUND_UP() into a shift:
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by xe_migrate.c
>>> drivers/gpu/drm/xe/xe_migrate.o:(pte_update_size) in archive vmlinux.a
There are two instances in this function. Change the first to
use an open-coded shift with the same behavior, and the second
one to a 32-bit calculation, which is sufficient here as the size
is never more than 2^32 pages (16TB).

All the components of YUV420 over DP are added. Therefore, let's mark the
connector property as true for DP connector when the DP type is not eDP
and when there is a CDM block available.
Changes in v3:
- Move setting the connector's ycbcr_420_allowed parameter so
that it is not dependent on if the dp_display is not eDP
Changes in v2:
- Check for if dp_catalog has a CDM block available instead of
checking if VSC SDP is allowed when setting the dp connector's
ycbcr_420_allowed parameter

Adjust the encoder format programming in the case of video mode for DP
to accommodate CDM related changes.
Changes in v4:
- Remove hw_cdm check in dpu_encoder_needs_periph_flush()
- Remove hw_cdm check when getting the fmt_fourcc in
dpu_encoder_phys_vid_enable()
Changes in v2:
- Move timing engine programming to a separate patch from this
one
- Move update_pending_flush_periph() invocation completely to
this patch
- Change the logic of dpu_encoder_get_drm_fmt() so that it only
calls drm_mode_is_420_only() instead of doing additional
unnecessary checks
- Create new functions msm_dp_needs_periph_flush() and it's
supporting function dpu_encoder_needs_periph_flush() to check
if the mode is YUV420 and VSC SDP is enabled before doing a
peripheral flush
