[PATCH v5 0/9] ASoC: rockchip: Parse dai links from dts

[PATCH v5 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 v5:
Allow searching for dai driver name in snd_soc_find_dai, instead of
hacking non-zero device id to avoid legay dai naming.

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 v5 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.

I would still rather keep the existing property documented (the binding
does need to be fixed) than remove it.  It's better practice and it's
not costing a huge amount.

sorry, i should explain more in the commit msg...

just to clarify, this property is replaced by 
"realtek,dmic-init-delay-ms" in rt5514 driver:

a5461fd6c8f7 ASoC: rt5514: Add the DMIC initial delay to wait it ready.

which does exactly the same thing as the old one: perform a delay after 
set clk...

i can do that if you still insist to keep it, since it's harmless :)
