Driver Changes: - Add extra delay to make MTP SDM845 work. - Small fixes to virtio, vkms, sii902x, sii9234, ast, mcde, analogix, rockchip. - Add zpos and ?BGR8888 support to meson. - More removals of drm_os_linux and drmP headers for amd, radeon, sti, r128, r128, savage, sis. - Allow synopsis to unwedge the i2c hdmi bus. - Add orientation quirks for GPD panels. - Edid cleanups and fixing handling for edid < 1.2. - Add runtime pm to stm. - Handle s/r in dw-hdmi. - Add hooks for power on/off to dsi for stm. - Remove virtio dirty tracking code, done in drm core. - Rework BO handling in ast and mgag200. Tiny conflict in drivers/gpu/drm/amd/display/dc/clk_mgr/clk_mgr.c, needed #include to make it compile.

drm: Add atomic variants for bridge enable/disable

2019-06-13T17:00:29+00:00

This patch adds atomic variants for all of pre_enable/enable/disable/post_disable bridge functions. These will be called from the appropriate atomic helper functions. If the bridge driver doesn't implement the atomic version of the function, we will fall back to the vanilla implementation. Note that some drivers call drm_bridge_disable directly, and these cases are not covered. It's up to the driver to decide whether to implement both atomic_disable and disable, or if it's not necessary.

drm: bridge: Add dual_link field to the drm_bridge_timings structure

2019-06-07T23:36:04+00:00

Extend the drm_bridge_timings structure with a new dual_link field to indicate that the bridge's input bus carries data on two separate physical links. The first use case is LVDS dual-link mode where even- and odd-numbered pixels are transferred on separate LVDS links.

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

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
