5d8c0417ea drm/msm/mdp5: fix reading hw revision on db410c platform
Since the commit commit c6122688f2 ("drm/msm/mdp5: stop overriding
drvdata") reading the MDP5 hw revision on db410c will crash the board
as the MDSS_GDSC is not enabled. Revert a part of the offending commit
(moving rpm enablement) and set priv->kms earlier. This make it possible
to use pm_runtime_get_sync() during read_mdp_hw_revision(), which will
power up both the MDP5 and MDSS devices.

0b55f6bc46 drm/msm/dpu1: Account for DSC's bits_per_pixel having 4 fractional bits
According to the comment this DPU register contains the bits per pixel
as a 6.4 fractional value, conveniently matching the contents of
bits_per_pixel in struct drm_dsc_config which also uses 4 fractional
bits.  However, the downstream source this implementation was
copy-pasted from has its bpp field stored _without_ fractional part.

This makes the entire convoluted math obsolete as it is impossible to
pull those 4 fractional bits out of thin air, by somehow trying to reuse
the lowest 2 bits of a non-fractional bpp (lsb = bpp % 4??).

The rest of the code merely attempts to keep the integer part a multiple
of 4, which is rendered useless thanks to data |= dsc->bits_per_pixel <<
12; already filling up those bits anyway (but not on downstream).

0b33a33bd1 drm/msm: Fix return type of mdp4_lvds_connector_mode_valid
The mode_valid field in drm_connector_helper_funcs is expected to be of

enum drm_mode_status (* mode_valid) (struct drm_connector *connector,
                                     struct drm_display_mode *mode);

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of mdp4_lvds_connector_mode_valid should be changed from
int to enum drm_mode_status.

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.

9811913a6d drm/msm/dpu: populate wb or intf before reset_intf_cfg
dpu_encoder_helper_phys_cleanup() was not populating neither
wb or intf to the intf_cfg before calling the reset_intf_cfg().

This causes the reset of the active bits of wb/intf to be
skipped which is incorrect.

Fix this by populating the relevant wb or intf indices correctly.
