Subject: [PATCH] ASoC: amd: acp: Add support for Maxim amplifier codec
Git-commit: cabc3acec02a3fb63efaba8ac892b54e823cd111
Patch-mainline: v5.16-rc1
References: jsc#PED-850

In newer chrome boards we have max98360a as an amplifier codec.
Add support for max98360a in generic machine driver and configure
driver data to enable SOF sound card support on newer boards .
