2020-11-20drm/meson: dw-hdmi: Disable clocks on driver teardownMarc Zyngier1-14/+29
The HDMI driver request clocks early, but never disable them, leaving the clocks on even when the driver is removed. Fix it by slightly refactoring the clock code, and register a devm action that will eventually disable/unprepare the enabled clocks.

2020-11-20drm/panel: s6e63m0: Fix init sequenceLinus Walleij1-8/+10
The init sequence consist of a number of unknown settings for the display controller. This patch achieves two things: - Fix an error that must have happened when the driver was converted from the backlight subsystem: the 0xb8 configuration command was lost and added as a tail to the previous command. - Update some minor settings in some bytes here and there according to changes in the Samsung GT-I9070 and Samsung GT-S7710 code dumps. Since two other devices use these settings they probably reflect trimmings later found to be better for the display rather than customizations for these devices.

2020-11-20drm: Pass the full state to connectors atomic functionsMaxime Ripard7-18/+31
The current atomic helpers have either their object state being passed as an argument or the full atomic state.

Note that the frontend is only the /dev/agp ioctl interface, which per Adam is only used by the i810 userspace drivers.

In the macro drm_mm_for_each_hole() 'hole_end' is provided as a container for 'hole_start + pos->hole_size', but is not utilised in this use-case. We cannot simply delete the variable, so here we tell the compiler that we're intentionally discarding the read value.
