We found Designware hdmi driver only support audio clock config, we can not play sound through it.
To add Designware HDMI Audio support, we make those patch set:
1): modify n/cts config order, according to dw_hdmi document.
2): add Audio Sample Channel Status config interfaces to dw_hdmi driver.
3): add audio support for more display resolutions(eg. 800x600).
4): add audio support for No-CEA display resolutions.
5): fixed dw_hdmi irq bug, add irq control to suspend/resume interfaces.
6): add suspend/resume callback for dw_hdmi rockchip driver.
7): filter interlace mode in rockchip vop driver.
8): add hdmi audio config interfaces to dw_hdmi driver.
9): creat "dw_hdmi-audio" platform device in dw_hdmi driver.
10): add codec driver for hdmi audio, callback dw_hdmi audio config functions.
11): add sound driver for hdmi audio, creat hdmi audio sound card.
12): add dt-bings file and add hdmi_audio node to corresponding dt file.
Changes in v2:
- adjust n/cts setting order
- Add audio sample channel status setting
- Add irq control to suspend/resume interfaces
- Add suspend/resume support for dw_hdmi_rockchip driver
- filter interlace display mode for rockchip vop
- add more n/cts combinations for more display resolutions
- enable audio support for No-CEA display mode
- Add audio config interfaces to dw_hdmi driver
- Update the audio control interfaces
- Update dw_hdmi audio control interfaces, and adjust jack report process
- give "codec-name" & "codec-dai-name" an const name
- remove codec-name and codec-dai-name
- rename rockchip,rockchip-hdmi-audio.txt to rockchip,rockchip-dw-hdmi-audio.txt
