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.

The dependent change on hdmi-codec.c

commit 6fa5963c37a2 ("ASoC: hdmi-codec: Add an op to set callback function for plug event")

has been merged to upstream.

Changes from v8 to v9:

1. rockchip_max98090:
   Use the presence of rockchip,audio-codec to determine the presense of max98090
   in sound card.
   Use the presence of rockchip,hdmi-codec to determine the presence of HDMI in
   sound card.
   Remove the compatible strings added in v8.

2. #include <sound/hdmi-codec.h> should be in the patch of adding HDMI jack support.
