From fa73de8793fbbace70281f6e40fdd1831d6e14b6 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 1 May 2020 15:35:34 +0200 Subject: [PATCH] dt-bindings: sound: wm8994: Correct required supplies based on actual implementaion [ Upstream commit 8c149b7d75e53be47648742f40fc90d9fc6fa63a ] The required supplies in bindings were actually not matching implementation making the bindings incorrect and misleading. The Linux kernel driver requires all supplies to be present. Also for wlf,wm8994 uses just DBVDD-supply instead of DBVDDn-supply (n: <1,3>).
