Subject: [PATCH 0/8] drm: bridge: dw_hdmi: Misc enable/disable, CEC and EDID cleanup

This series ensure poweron/poweroff and CEC phys addr invalidation is
happening under drm mode_config mutex lock, and also ensure EDID is
updated (when the dw-hdmi connector is used) after a hotplug pulse.

These changes has mainly been tested on Rockchip devices together with a
forthcoming series that add HDMI 2.0 4K@...z support to RK3228, RK3328,
RK3399 and RK3568.

Rockchip use the dw-hdmi connector so this should also be validated with
a driver that use the bridge connector.

Jonas Karlman (8):
  drm: bridge: dw_hdmi: Call poweron/poweroff from atomic enable/disable
  drm: bridge: dw_hdmi: Use passed mode instead of stored previous_mode
  drm: bridge: dw_hdmi: Fold poweron and setup functions
  drm: bridge: dw_hdmi: Remove previous_mode and mode_set
  drm: bridge: dw_hdmi: Invalidate CEC phys addr from connector detect
  drm: bridge: dw_hdmi: Remove cec_notifier_mutex
  drm: bridge: dw_hdmi: Update EDID during hotplug processing
  drm: bridge: dw_hdmi: Use display_info is_hdmi and has_audio
