[PATCH v2 9/9] ASoC: codecs: lpass-wsa-macro: add support for SM8550

From: Krzysztof Kozlowski
Date: Mon Mar 13 2023 - 03:58:42 EST


Add support for the WSA macro codec on Qualcomm SM8550. SM8550 does not
use NPL clock, thus add flags allowing to skip it.

Changes since v1:
1. Move the flag define to common header
