[PATCH v2 0/4] Add HDMI jack support on RK3288

From: Cheng-Yi Chiang
Date: Wed Jul 10 2019 - 03:08:14 EST

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


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
- 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.
