From 3a3610aaa9dce8ef1257bb42ac7f0fe2b5809a54 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 9 May 2022 14:10:55 +0200 Subject: [PATCH] ASoC: wm8940: add devicetree support This adds devicetree support to the wm8940 codec driver. With a DT-based kernel, there is no board-specific setting to select the driver so allow it to be manually chosen.
