> The current set of devices managed in this patchset are conformant with the

> and platform firmware specification is not complete at this time. They do
> however rely on the hierarchical addressing required by the SDCA standard.
> Future devices conformant with SDCA 1.0 should rely on a class driver.
> 
> This series adds support for the hierarchical SDCA addressing and extends
> regmap. It then provides 3 codecs for RT711-sdca headset codec, RT1316
> amplifier and RT715-scda microphone codec.
> 
> Note that the release of this code before the formal adoption of the SDCA
> 1.0 specification was formally endorsed by the MIPI Board to make sure
> there is no delay for Linux-based support of this specification.

Hi Vinod/Mark,

Could we take this series into Vinod's tree with Mark's Acked-by?
It failed to build on Mark's tree.
