2020-12-15drm/omap: dsi: drop virtual channel logicSebastian Reichel3-49/+12
This drops the virtual channel logic. Afterwards DSI clients request their channel number and get the virtual channel with the same number or -EBUSY if already in use. The change here is not strictly speaking correct, as it combines the VC (DSI's "configuration block") and virtual channel ID (the ID sent in the DSI packets). But as we currently only support a single DSI command mode panel, this works fine: we always use VC0, and VC ID 0.

2020-12-15drm/omap: Enable COLOR_ENCODING and COLOR_RANGE properties for planesJyri Sarha3-42/+93
Adds support for COLOR_ENCODING and COLOR_RANGE properties to omap_plane.c and dispc.c. The supported encodings and ranges are presets are: For COLOR_ENCODING: - YCbCr BT.601 (default) - YCbCr BT.709 For COLOR_RANGE: - YCbCr limited range - YCbCr full range (default) Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201103080310.164453-6-tomi.valkeinen@ti.com

2020-12-15drm/omap: Implement CTM property for CRTC using OVL managers CPR matrixJyri Sarha1-2/+37
Implement CTM color management property for OMAP CRTC using DSS overlay manager's Color Phase Rotation matrix. The CPR matrix does not exactly match the CTM property documentation. On DSS the CPR matrix is applied after gamma table look up. However, it seems stupid to add a custom property just for that.

2020-12-15drm/omap: use degamma property for gamma tableTomi Valkeinen1-6/+6
omapdrm supports gamma via GAMMA_LUT property. However, the HW we have is: gamma -> ctm -> out instead of what the model DRM framework uses: ctm -> gamma -> out As the following patches add CTM support for omapdrm, lets first fix the gamma. This patch changes the property from GAMMA_LUT to DEGAMMA_LUT, and thus we will have: degamma -> ctm -> out and the legacy ioctl will continue working as before.

2020-12-15drm: automatic legacy gamma supportTomi Valkeinen1-1/+0
To support legacy gamma ioctls the drivers need to set drm_crtc_funcs.gamma_set either to a custom implementation or to drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the latter. We can simplify this by making the core handle it automatically. Move the drm_atomic_helper_legacy_gamma_set() functionality into drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.
