Re: [PATCH v4] ASoC: dt-bindings: omap-mcpdm: Convert to DT schema

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey, before making a new patch I'll just list the changes that need to
be done according to this discussion.
Change maintainer
Change clocks to only include maxItems: 1
Change clock-names to include
items:
 - const: pdmclk
Use correct address in example
Use flags for interrupt in example

Best regards,
Mithil
