Subject: [PATCH 2/2] ASoC: dt-bindings: qcom,wcd9335: Convert to dtschema
Convert the Qualcomm WCD9335 audio codec binding to DT schema.
Changes against original binding:
1. Drop "mclk2" from clocks as neither Linux driver nor DTS uses it.
2. Do not require vdd-micbias-supply as several DTS do not provide it.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
Few DTS boards have incomplete WCD9335 node causing dtbs_check warnings.
These are fixed here:
