The driver references CWB array from SM8650, but should use the Eliza
specific, which has different register space sizes. This should not
have noticeable impact on function but is indeed confusing, since the
Eliza table is used for .cwb_count.

Due to historical reasons we ended up with dummy values being specified
for MST-related interfaces some of them had INTF_NONE, others had
non-existing DP controller indices. Those workarounds are no longer
necessary. Fix types and indices for all DP-MST related INTF instances.
The only exception is INTF_3 on SC8180X, which has unique design. It can
be used either with INTF_0 / DP0 or with INTF_4 / DP1. This interface is
left with the dummy value until somebody implements necessary bits for
that platform.

there is some code churn due to register shuffling in A8x. So, split out

Recent chipsets like Glymur supports a new mechanism for SKU detection.
A new CX_MISC register exposes the combined (or final) speedbin value
from both HW fuse register and the Soft Fuse register. Implement this new
SKU detection along with a new quirk to identify the GPUs that has soft
fuse support.
There is a side effect of this patch on A4x and older series. The
speedbin field in the MSM_PARAM_CHIPID will be 0 instead of 0xffff. This
should be okay as Mesa correctly handles it. Speedbin was not even a
thing when those GPUs' support were added.

msm_ioctl_gem_info_get_metadata() always returns 0 regardless of
errors. When copy_to_user() fails or the user buffer is too small,
the error code stored in ret is ignored because the function
unconditionally returns 0. This causes userspace to believe the
ioctl succeeded when it did not.
Additionally, kmemdup() can return NULL on allocation failure, but
the return value is not checked. This leads to a NULL pointer
dereference in the subsequent copy_to_user() call.
Add the missing NULL check for kmemdup() and return ret instead of 0.
Note that the SET counterpart (msm_ioctl_gem_info_set_metadata)
correctly returns ret.

Previously, in case there was no more work to do, recover worker
wouldn't trigger recovery and would instead rely on the gpu going to
sleep and then resuming when more work is submitted.
Recover_worker will first increment the fence of the hung ring so, if
there's only one job submitted to a ring and that causes an hang, it
will early out.
There's no guarantee that the gpu will suspend and resume before more
work is submitted and if the gpu is in a hung state it will stay in that
state and probably trigger a timeout again.
Just stop checking and always recover the gpu.

Add video and command mode destination format mappings for RGB101010,
and extend the VID_CFG0 DST_FORMAT bitfield to 3 bits to accommodate
the new format value.
Make sure this is guarded behind MSM_DSI_6G_VER >= V2.1.0 as anything
older does not support this.
Required for 10 bit panels such as the BOE BF068MWM-TD0 found on the
Nothing Phone (3a).

The MSM8998 DSI controller is v2.0.0 as stated in commit 7b8c9e2030
("drm/msm/dsi: Add support for MSM8998 DSI controller"). The value was
always correct just the name was wrong.
Rename and reorder to maintain version sorting.

The content of every half of screen is sent out via one interface in
dual-DSI case. The content for every interface is blended by a LM
pair in quad-pipe case, thus a LM pair should not blend any content
that cross the half of screen in this case. Clip plane into pipes per
left and right half screen ROI if topology is quad pipe case.
The clipped rectangle on every half of screen is futher handled by two
pipes if its width exceeds a limit for a single pipe.
For non-virtual-plane case, there is always one stage config to serve
a LM or LM pair. So the clipping does not occur when interating stages
in this case. The plane is mapped to 2 pipes only when width or clock
rate exceeds hardware constrain within stage check.

Currently, mapping plane to SSPP occurs during the plane check phase for
non-virtual plane case. The SSPP allocation and plane mapping occurs during
CRTC check phase for virtual plane case. Defer these SSPP operations until
CRTC check stage to unify the 2 cases, and ease later revisement for
quad-pipe change.

All MDP / DPU implementations except for MSM8996 use VBIF_RT (or the
only VBIF) for WB2. Writeback on MSM8996 is not supported (nor planned
to be supported). In order to simplify the driver, drop the field form
the struct dpu_wb_cfg.
