Subject: [PATCH] soundwire: add new mclk_freq field for properties
Git-commit: 82fc8d06501a0694bfb1ada8ba69372cbc297fb9
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

To help pass platform-specific values, add a new field that can either
be set by the Master driver or read from firmware (BIOS/DT).
