[PATCH 1/6] ASoC: SOF: amd: remove unused code

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

 



--- Begin Message ---
During initial SOF driver bring up on AMD platforms, only DMIC
support was added. As of today, we have a complete SOF solution for
I2S endpoints along with DMIC endpoint.
This code is no longer required.
Remove unused code from RMB and RN platform ACP PCI driver.
