Subject: [PATCH v4 0/5] 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 v3 to v4:
- hdmi-codec.h: Modify the hook_plugged_cb ops to take an additional argument,
  that is, the pointer to struct device for codec device.
- dw-hdmi-i2s-audio.c: Simplify the registration of callback so it uses
  dw_hdmi_set_plugged_cb exported by dw-hdmi.c.
- dw-hdmi.c: Simplify the flow to invoke callback since now dw_hdmi has a
  pointer to codec device as callback argument. There is no need to rely
  on driver data of other driver.
- dw-hdmi.c: Minor change for readability.
- synopsys/Kconfig: Fix the dependency of hdmi-codec in Kconfig.
- Fixed the incorrect FROMLIST title of patch 5/5.

Cheng-Yi Chiang (5):
  ASoC: hdmi-codec: Add an op to set callback function for plug event
  drm: bridge: dw-hdmi: Report connector status using callback
  drm: dw-hdmi-i2s: Use fixed id for codec device
  ASoC: rockchip_max98090: Add dai_link for HDMI
  ASoC: rockchip_max98090: Add HDMI jack support
