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.
