[PATCH v4 0/9] ASoC: rockchip: Parse dai links from dts

[PATCH v4 0/9] ASoC: rockchip: Parse dai links from dts

[Jeffy Chen]

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.

[PATCH v4 5/9] arm64: dts: rockchip: Update rt5514 devices' compatible for Gru

[Jeffy Chen]

Currently the rt5514 i2c driver and rt5514 spi driver are using the same
compatible string.

Add additional unused compatible strings to identify them for Gru
boards.

Well, obviously not used since they don't even match.
