According to drm_plane_create_zpos_property() function documentation, all planes zpos range should be set if zpos property is supported. However, the rcar-du driver didn't set primary plane zpos range. Since the primary plane's zpos is fixed, set it immutably.

The zpos property is used by userspace to sort the order of planes.

2020-05-14dt-bindings: display: bridge: Convert simple-bridge bindings to YAMLLaurent Pinchart4-151/+99
The simple-bridge driver supports multiple simple or dumb bridges, covered by different compatible strings but otherwise identical DT bindings. Some of those bridges have undocumented bindings, while others are documented in text form in separate files. Group them all in a single binding and convert it to YAML. The psave-gpios property of the adi,adv7123 is dropped, as it isn't supported by the driver and isn't specified in any DT file upstream. Support for power saving is available through the enable-gpios property that should cover all the needs of the ADV7123 (as the device only has a /PSAVE pin and no enable pin).

2020-05-07drm/amd/display: Fix vblank and pageflip event handling for FreeSyncNicholas Kazlauskas1-82/+55
[Why] We're sending the drm vblank event a frame too early in the case where the pageflip happens close to VUPDATE and ends up blocking the signal. The implementation in DM was previously correct *before* we started sending vblank events from VSTARTUP unconditionally to handle cases where HUBP was off, OTG was ON and userspace was still requesting some DRM planes enabled. As part of that patch series we dropped VUPDATE since it was deemed close enough to VSTARTUP, but there's a key difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be blocked if we're holding the pipe lock. There was a fix recently to revert the unconditional behavior for the DCN VSTARTUP vblank event since it was sending the pageflip event on the wrong frame - once again, due to blocking VUPDATE and having the address start scanning out two frames later. The problem with this fix is it didn't update the logic that calls drm_crtc_handle_vblank(), so the timestamps are totally bogus now. [How] Essentially reverts most of the original VSTARTUP series but retains the behavior to send back events when active planes == 0. Some refactoring/cleanup was done to not have duplicated code in both the handlers.
