From c143755d8cce31e770234732ff23134993b0550f Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 17 Feb 2025 14:01:59 +0000 Subject: ASoC: SDCA: Add helper to write out defaults and fixed values The concept of an SDCA default value differs slightly from the regmap usage of the term. An SDCA default is a value that is parsed from DisCo and then written out to the hardware if no user value has superceded it. Add a helper function that will iterate through all the SDCA Controls and write out any default values. After these have been written out once they will exist in the cache and that will take care of any user values superceeding them. The code here also writes out any Controls with a fixed value as there is only one available value for these Controls there is no point in allowing the user to select them, simply treat them similarly to a default.
