Subject: [PATCH v2 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.

Changes from v1 to v2:
- hdmi-codec.c: cleanup the sequence of hdmi_codec_jack_report and
  hdmi_codec_set_jack_detect.
- dw-hdmi.c: change argument of hdmi_codec_plugged_cb so it takes a generic
  device which has hdmi_codec_priv in its drvdata.
- dw-hdmi.c: add a helper function handle_plugged_change to check audio
  platform device and codec platform device before calling callback.
- dw-hdmi-c: avoid setting callback function if audio platform device or
  codec platform device is missing.
- rockchip_max98090: fix the checking of return code when setting sysclk
  on cpu_dai and codec_dai. cpu_dai error should be reported. For HDMI
  codec_dai, there is no need to set sysclk.

Cheng-Yi Chiang (4):
  ASoC: hdmi-codec: Add an op to set callback function for plug event
  drm: bridge: dw-hdmi: Report connector status using callback
  ASoC: rockchip_max98090: Add dai_link for HDMI
  ASoC: rockchip_max98090: Add HDMI jack support
