drm/bridge: use bus flags in bridge timings

2019-03-18T09:42:13+00:00

The DRM bus flags convey additional information on pixel data on the bus. All current available bus flags might be of interest for a bridge. Remove the sampling_edge field and use bus_flags. In the case at hand a dumb VGA bridge needs a specific data enable polarity (DRM_BUS_FLAG_DE_LOW).

drm: Use new DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags

2019-03-18T09:42:13+00:00

The DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE and DRM_BUS_FLAG_SYNC_(POS|NEG)EDGE flags are deprecated in favour of the new DRM_BUS_FLAG_PIXDATA_(DRIVE|SAMPLE)_(POS|NEG)EDGE and new DRM_BUS_FLAG_SYNC_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags. Replace them through the code. This effectively changes the value of the .sampling_edge bridge timings field in the dumb-vga-dac driver. This is safe to do as no driver consumes these values yet.

drm: bridge: Constify mode arguments to bridge .mode_set() operation

2019-01-14T01:51:14+00:00

The mode and ajusted_mode passed to the bridge .mode_set() operation should never be modified by the bridge (and are not in any of the existing bridge drivers). Make them const to make this clear. Signed-off-by: Laurent Pinchart Reviewed-by: Daniel Vetter

drm/bridge: Rename argument from crtc to bridge

Why is the argument to ->mode_valid() called "crtc"? I guess a copy/paste error. Fix it. Reviewed-by: Laurent Pinchart Signed-off-by: Linus Walleij Link: https://patchwork.freedesktop.org/patch/msgid/20180129095531.4557-1-linus.walleij@linaro.org

drm/bridge: Provide a way to embed timing info in bridges

2018-01-12T08:44:03+00:00

After some discussion and failed patch sets trying to convey the right timing information between the display engine and a bridge using the connector, I try instead to use an optional timing information container in the bridge itself, so that display engines can retrieve it from any bridge and use it to determine how to drive outputs.
