Introduce struct drm_mipi_dbi_plane_state that contains state related to
MIPI DBI. It currently only inherits from struct drm_shadow_plane_state,
so that MIPI DBI drivers can use the vmap'ed GEM-buffer memory. Implement
state helpers, the {begin,end}_fb_access helpers and wire up everything.
With
MIPI DBI drivers validate each mode against their native resolution.
Add this test to st7586.

Call drm_dev_enter() and drm_dev_exit() in the outer-most callbacks
of the modesetting pipeline. If drm_dev_enter() fails, the driver can
thus avoid unnecessary work.

Use the buffer mappings provided by shadow-plane helpers. As the
mappings are established while the commit can still fail, errors
are now reported correctly to callers.

The helper drm_gem_simple_display_pipe_prepare_fb() is simple-KMS'
default implementation for prepare_fb. Remove the call from drivers
that set it explicitly. Then inline the helper into the only caller
within simple-kms helpers and remove . No functional changes.

Move the vmap/vunmap blocks from the inner fb_dirty helpers into the
MIPI DBI update helpers. The function calls can result in waiting and/or
processing overhead. Reduce the penalties by executing the functions once
in the outer-most function of the pipe update.
This change also prepares for MIPI
Introduce DRM_MIPI_DBI_SIMPLE_DISPLAY_PIPE_FUNCS to initialize MIPI-DBI
helpers to default values and convert drivers. The prepare_fb function
set by some drivers is called implicitly by simple-kms helpers, so leave
it out.

Convert the MIPI-DBI-based drivers to shadow-plane helpers. The
drivers vmap/vunmap GEM buffer memory during the atomic commit.
Shadow-plane helpers automate this process.
Patches 1 to 4 prepare the MIPI code for the change and simplify
the restof the patchset.
Patches 5 to 7 rework the vmap

Pin each crtc with one encoder. This arrangement will
disallow crtc switching between encoders and also will
facilitate to advertise certain features on crtc based
on encoder type.
Changes in v1:
- use drm_for_each_encoder macro while iterating through
encoder list (Dmitry)
Changes in v2:
-
Add color management support for the crtc provided there are
enough dspps that can be allocated from the catalog.
Changes in v1:
- cache color enabled state in the dpu crtc obj (Dmitry)
- simplify dspp allocation while creating crtc (Dmitry)
- register for color when crtc is created (Dmitry)
Since DRM encoder type for few encoders can be similar
(like eDP and DP), get the connector type for a given
encoder to differentiate between builtin and pluggable
displays.
Changes in v1:
- add connector type in the disp_info (Dmitry)
- add helper functions to know encoder type
- update commit
