Subject: [PATCH 1/3] ASoC: dt-bindings: wlf,wm8960: Convert to dtschema
Convert the Wolfson WM8960 audio codecs bindings to DT schema.
Changes against original binding:
1. Document clocks and clock-names - already present in DTS and used
by Linux driver.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
One DTS warning still remains:
uniphier-pxs2-gentil.dtb: wm8960@1a: Unevaluated properties are not allowed ('port@0' was unexpected)
I am not sure if this is correct usage of endpoints. I would assume the
codec should be used only as DAI.
