drm/rockchip: Don't use atomic constructs for psr

2018-03-08T22:28:53Z

Instead of using timer and spinlocks, use delayed_work and mutexes for rockchip psr. This allows us to make blocking calls when enabling/disabling psr (which is sort of important given we're talking over dpcd to the display).

drm/rockchip: Add device links for master and components

2018-03-01T13:24:01Z

Since we are trying to access components' resources in the master's suspend/resume PM callbacks(e.g. panel), add device links to correct the suspend/resume and shutdown ordering.

drm/rockchip: support prime import sg table

2018-02-18T10:16:40Z

The prime fd to handle ioctl was not used with rockchip before. Support was added in order to pass graphics_Gbm and to support potential uses within Chrome OS (e.g. zero-copy video decode, camera).

drm/rockchip: Use drm_fb_helper_lastclose() and _poll_changed()

2017-12-08T12:08:06Z

This driver can use drm_fb_helper_lastclose() as its .lastclose callback. It can also use drm_fb_helper_output_poll_changed() as its .output_poll_changed callback.
