Subject: [PATCH v7 0/4] Add HDMI jack support on RK3288

This patch series supports HDMI jack reporting on RK3288, which uses
DRM dw-hdmi driver and hdmi-codec codec driver.

The previous discussion about reporting jack status using hdmi-notifier
and drm_audio_component is at

https://lore.kernel.org/patchwork/patch/1083027/

The new approach is to use a callback mechanism that is
specific to hdmi-codec.

The dependent change on hdmi-codec.c

https://patchwork.kernel.org/patch/11047447

has been picked up by Mark Brown in ASoC tree for-5.4 branch.

Changes from v6 to v7:

1. rockchip_max98090: Use phandle of HDMI from DTS to find
   codec_dai. With this we don't need to set fixed id for the
   created hdmi-audio-codec device.

Cheng-Yi Chiang (4):
  drm: bridge: dw-hdmi: Report connector status using callback
  ASoC: rockchip-max98090: Add description for rockchip,hdmi-codec
  ASoC: rockchip_max98090: Add dai_link for HDMI
  ASoC: rockchip_max98090: Add HDMI jack support
