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
