Subject[RFC PATCH 0/6] Those patches is used for dw_hdmi audio.

rk3288 use Designware HDMI IP, Designware HDMI supports four interfaces to
config hdmi audio(I2S, S/PDIF, Generic Parallel Audio, AHB Audio DMA), but
rk3288 only support two ways to config hdmi audio(I2S, S/PDIF), So we take
I2S as hdmi audio operation interfaces, and then treat hdmi audio as an
standard ALSA devices(only got platback function).

Four things we have done:
1. modify the audio part of dw_hdmi drivers for rk3288 platform specific.
2. add codec driver for hdmi audio, and creat codec device dynamically in
hdmi driver probe function, using platform_register_device_full way, so
that hdmi codec driver can connected with hdmi driver.
3. add sound driver for hdmi audio, creat hdmi audio sound card.
4. add dt-bings file and add hdmi_audio node to corresponding dt file.

those patch is depend on patch by Andy Yan
