drm: Drop drm_edid.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_edid.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_edid.h. Quite a few placs do currently depend on drm_edid.h without actually including it directly. All of those need to be fixed up. v2: Fix up i915 and msm some more v3: Fix alphabetical ordering (Sam) Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220614090245.30283-1-ville.syrjala@linux.intel.com Acked-by: Sam Ravnborg Acked-by: Jani Nikula

drm: bridge: simple-bridge: Delegate operations to next bridge

2020-06-23T17:52:22+00:00

Instead of poking into the DT node of the next bridge for its DDC bus and implementing the .get_modes() and .detect() connector operations manually, retrieve the next bridge in the chain and delegate these operations to it.

drm/bridge: simple-bridge: Add support for the TI OPA362

2020-02-26T11:31:33+00:00

The TI OPA362 is an analog video amplifier controlled through a GPIO. Add support for it to the simple-bridge driver.

drm/bridge: simple-bridge: Add support for non-VGA bridges

2020-02-26T11:31:32+00:00

Create a new simple_bridge_info structure that stores information about the bridge model, and store the bridge timings in there, along with the connector type. Use that new structure for of_device_id data. This enables support for non-VGA bridges.
