Subject: [PATCH v2 0/3] ASoC: mediatek: mt8183-afe-pcm: Shorten source code

Hi folks,

Changes since v1:
- Rebased on top of -next, dropping changes that cover the DMA address
  MSB registers

This series is meant as an example on how to use macros and range cases
to shorten the MediaTek audio frontend drivers. The drivers have large
tables describing the registers and register fields for every supported
audio DMA interface. (Some are actually skipped!) There's a lot of
duplication which can be eliminated using macros. This should serve as
a reference for the MT8196 AFE driver that I had commented on.

The three patches tackle separate tables in the driver. The remaining
one that could be tackled is the list of DAIs; but that one has more
differences between each entry, so I haven't done it yet.

Please take a look.

Thanks
ChenYu
