drm/fourcc: Add char_per_block, block_w and block_h in drm_format_info
For some pixel formats .cpp structure in drm_format info it's not
enough to describe the peculiarities of the pixel layout, for example
tiled formats or packed formats at bit level.
What's implemented here is to add three new members to drm_format_info
that could describe such formats:
- char_per_block[3]
- block_w[3]
- block_h[3]
char_per_block will be put in a union alongside cpp, for transparent
compatibility with the existing format descriptions.
Regarding, block_w and block_h they are intended to be used through
their equivalent getters drm_format_info_block_width /
drm_format_info_block_height, the reason of the getters is to abstract
the fact that for normal formats block_w and block_h will be unset/0,
but the methods will be returning 1.
Additionally, convenience function drm_format_info_min_pitch had been
added that computes the minimum required pitch for a given pixel
format and buffer width.
Using that the following drm core functions had been updated to
generically handle both block and non-block formats:
- drm_fb_cma_get_gem_addr: for block formats it will just return the
beginning of the block.
- framebuffer_check: Use the newly added drm_format_info_min_pitch.
- drm_gem_fb_create_with_funcs: Use the newly added
drm_format_info_min_pitch.
- In places where is not expecting to handle block formats, like fbdev
helpers I just added some warnings in case the block width/height
are greater than 1.
Changes since v3:
- Add helper function for computing the minimum required pitch.
- Improve/cleanup documentation
Changes since v8:
- Fixed build on 32bits arm architectures, with:
- return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane],

drm/bridge/synopsys: dsi: add ability to have glue-specific attach and detach
With the regular means of adding the dsi-component in probe it creates
a race condition with the panel probing, as the panel device only gets
created after the dsi-bus got created.
When the panel-driver is build as a module it currently fails hard as the
panel cannot be probed directly:
dw_mipi_dsi_bind()
__dw_mipi_dsi_probe()
creates dsi bus
creates panel device
triggers panel module load
panel not probed (module not loaded or panel probe slow)
drm_bridge_attach
fails with -EINVAL due to empty panel_bridge
Additionally the panel probing can run concurrently with dsi bringup
making it possible that the panel can already be found but dsi-attach
hasn't finished running.
To solve that cleanly we may want to only create the component after
the panel has finished probing, by calling component_add from the
host-attach dsi callback.
As that is specific to glue drivers, add a new struct for host_ops
so that glue drivers can tell the bridge to call specific functions
after the common host-attach and before the common host-detach run.

drm/bridge/synopsys: dsi: don't call __dw_mipi_dsi_probe from dw_mipi_dsi_bind
__dw_mipi_dsi_probe() does all the grabbing of resources and does it using
devm-helpers. So this is happening on each try of master bringup possibly
slowing down things a lot.
Drivers using the component framework may instead want to call
dw_mipi_dsi_probe separately in their probe function to setup resources
early. That way the dsi bus also gets created earlier and also not
recreated on each bind-try, so that attached panels can load their modules
and be probed way before the bridge-attach in the bind call.
So drop the call to __dw_mipi_dsi_probe and modify the function to take
a struct dw_mipi_dsi instead of the platform-device.

afterwords we updated the core function to BUG() in order to catch any

drm/vc4: Set ->is_yuv to false when num_planes == 1
When vc4_plane_state is duplicated ->is_yuv is left assigned to its
previous value, and we never set it back to false when switching to
a non-YUV format.
Fix that by setting ->is_yuv to false in the 'num_planes == 1' branch
of the vc4_plane_setup_clipping_and_scaling() function.

drm/vc4: Fix X/Y positioning of planes using T_TILES modifier
X/Y positioning of T-format buffers is quite tricky and the current
implementation was failing to position a plane using this format
correctly when the CRTC X, Y or both X and Y offsets were negative.
It was also failing when the SRC X/Y offsets were != 0.

drm/vc4: Move ->offsets[] adjustment out of setup_clipping_and_scaling()
The offset adjustment depends on the framebuffer modified, so let's
just move this operation in the DRM_FORMAT_MOD_LINEAR case inside

This we'll be able to fix offset calculation for
DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX.

drm/vc4: Use drm_atomic_helper_check_plane_state() to simplify the logic
drm_atomic_helper_check_plane_state() takes care of checking the
scaling capabilities and calculating the clipped X/Y offsets for us.
Rely on this function instead of open-coding the logic.
Incidentally, it seems to fix a problem we had with negative X/Y
positioning of YUV planes.
