From b53d47775651aa51bb98cdeb968dedb45699d9a1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 8 Dec 2023 11:09:25 +0100 Subject: [PATCH] ASoC: wm0010: Convert to GPIO descriptors This converts the WM0010 codec to use GPIO descriptors. It's a pretty straight-forward conversion also switching over the single in-tree user in the S3C Cragganmore module for S3C 6410.
