Currently we are using a fixed list of dai links in the driver. This serial of patches would let the driver parse dai links from dts, so that we can make some of them optional for future boards.
Tested on my chromebook bob(with cros 4.4 kernel), it still works after disabled rt5514 codecs in the dts.
Changes in v4: Use non-zero drv id to avoid legacy dai naming instead of switching to snd_soc_register_codec.
Changes in v3: Use compatible to match audio codecs -- Suggested-by Matthias Kaehlcke mka@chromium.org
Changes in v2: Let rockchip,codec-names be a required property, because we plan to add more supported codecs to the fixed dai link list in the driver.
