3cde792a55 drm/msm/dpu: get rid of cached flush_mask 
Instead of querying the CTL for the flush mask (for SSPP, LM or DSPP),
storing the mask in the mixer configuration and then pushing the mask to
the CTL, tell CTL to cache the flush in place.

Stop limiting zpos property values, we use normalized_zpos anyway. And
nothing stops userspace from assigning several planes to a single zpos

Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If

5ccdcecaf8 drm/msm: lookup the ICC paths in both mdp5/dpu and mdss devices 
The commit 6874f48bb8 ("drm/msm: make mdp5/dpu devices master
components") changed the MDP5 driver to look for the interconnect paths
in the MDSS device rather than in the MDP5 device itself. This was left
unnoticed since on my testing devices the interconnects probably didn't
reach the sync state.

Rather than just using the MDP5 device for ICC path lookups for the MDP5
devices, introduce an additional helper to check both MDP5/DPU and MDSS
nodes. This will be helpful for the MDP5->DPU conversion, since the
driver will have to check both nodes.

dpu_encoder_helper_phys_cleanup() was not populating neither

This causes the reset of the active bits of wb/intf to be

7b37523fb1 drm/msm/dpu: Move MISR methods to dpu_hw_util 
Move layer mixer specific MISR methods to generalized helper methods.
This will make it easier to add CRC support for other blocks in the
future.

Changes since V2:
- Reordered parameters so that offsets are after hw_blk_reg_map
- Fixed mismatched whitespace in bitmask definitions

58fc5d186d drm/msm/dpu: Move LM CRC code into separate method 
Move layer mixer-specific section of dpu_crtc_get_crc() into a separate
helper method. This way, we can make it easier to get CRCs from other HW
blocks by adding other get_crc helper methods.

Changes since V1:
- Move common bitmasks to dpu_hw_util.h
- Move common CRC methods to dpu_hw_util.c
- Update copyrights
- Change crcs array to a dynamically allocated array and added it as a
  member of crtc_state

Changes since V2:
- Put changes for hw_util into a separate commit
- Revert crcs array to a static array
- Add else case for set_crc_source to return EINVAL if no valid source
  is selected
- Add DPU_CRTC_MAX_CRC_ENTRIES macro

Changes since V3:
- Move crcs array into dpu_crtc_get_lm_crc
- Remove comment about crcs array in dpu_crtc_state struct
- Revert `lm` rename
- Remove DPU_CRTC_MAX_CRC_ENTRIES macro
- Return EINVAL in dpu_crtc_get_crc if no valid CRC source is set

Writeback block for sm8250 was using the default maxlinewidth
of 2048. But this is not right as it supports upto 4096.

This should have no effect on most resolutions as we are

intf and wb resources are not dependent on the rm global
state so need not be allocated during dpu_encoder_virt_atomic_mode_set().

Move the allocation of intf and wb resources to dpu_encoder_setup_display()

Since dpu_encoder_setup_display() already has protection against
setting invalid intf_idx and wb_idx, these checks can now
be dropped as well.

c28d76d360 drm/msm/dpu: Increment vsync_cnt before waking up userspace 
The 'vsync_cnt' is used to count the number of frames for a crtc.
Unfortunately, we increment the count after waking up userspace via
dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank().
drm_crtc_handle_vblank() wakes up userspace processes that have called
drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to
increase it won't.

Increment the count before calling into the drm APIs so that we don't
have to worry about ordering the increment with anything else in drm.
This fixes a software video decode test that fails to see frame counts
increase on Trogdor boards.
