[PATCH v5 0/3] ASoC: Add DMIC support for the AMD RPL platform

[PATCH v5 0/3] ASoC: Add DMIC support for the AMD RPL platform

[Mingyou Chen]

v2:
  - Reverse ACP CONFIG PIN from 10 to 14 for rpl
  - Remove the rpl folder
v3:
  - Remove rpl configuration from Kconfig and Makefile
v4:
  - Handle separate switch case for RPL platform (ACP Pin config)
v5:
  - Remove clangd generated compiler_attributes.h include statement

Mingyou Chen (3):
  ASoC: Add DMIC support for the AMD RPL platform
  ASoC: Drop RPL driver
  ASoC: Add quirk for Lecoo Bellator N176

[PATCH v5 2/3] ASoC: Drop RPL driver

[Mingyou Chen]

The RPL driver is no longer needed because its functionality has been
superseded by the YC driver

I think you have a typo here, which really confused me for a while.  You 
meant to say "reserve" but you typed "reverse".

This comment is in the incorrect location (and also has a typo).

I feel it should come right before this line so it's obvious that when 
on the RPL platform you handle the special case.

if (pci->revision == 0x62)
