[alsa-devel] [PATCH v3 0/15] Those patches is used for dw_hdmi audio support

[Yakir Yang]

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): fixed dw_hdmi irq bug, add irq control to suspend/resume interfaces.
2): add suspend/resume callback for dw_hdmi rockchip driver.
3): Warp irq control in functions.
4): Combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts()
5): Adjust n/cts config order.
6): Set ncts_atomic_write & cts_manual, according to dw_hdmi document.
7): Add audio support for more display resolutions(eg. 800x600).
8): Add audio support for No-CEA display resolutions.
9): Add Audio Sample Channel Status config interfaces to dw_hdmi driver.
10): add audio clock control interfaces o dw_hdmi driver.
11): creat "dw_hdmi-audio" platform device in dw_hdmi driver.
12): add codec driver for hdmi audio, callback dw_hdmi audio config functions.
13): add sound driver for hdmi audio, creat hdmi audio sound card.
14): add dt-bings file and add hdmi_audio node to corresponding dt file.


Changes in v3:
- Clear Hotplug interrupts before dw_hdmi_fb_register
- Wrap irq control in fucntions
- Setting the .pm member instead of suspend/resume
- Add ID registers parse and record
- Combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts()
- Only adjust the n/cts setting order
- Set ncts_atomic_write & cts_manual
- Determine whether sample channel should set by desig_id.
- Delete hdmi_audio_config interface and modify audio clock control functions
- Remove audio_config & get_connect_status callback functions
  and add write/read/mod register callback functions
- Keep audio format config function in dw-hdmi-audio driver
  and remove audio_config & get_connect_status functions,
  move jack control to dw-hdmi-audio completely.
- Delete the operation of jack in rockchip-hdmi-audio driver,
  get ready to switch to simple-audio-card driver.
- modify cpu-of-node to i2s-controller

Changes in v2:
- Add irq control to suspend/resume interfaces
- Add suspend/resume support for dw_hdmi_rockchip driver
- add more n/cts combinations for more display resolutions
- enable audio support for No-CEA display mode
- Add audio sample channel status setting
- 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
