Date: Thu, 17 Sep 2020 22:14:33 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Krzysztof Kozlowski <krzk@...nel.org>, Jonathan Bakker <xc-racer2@...e.ca>, Mark Brown <broonie@...nel.org>, Sasha Levin <sashal@...nel.org>, devicetree@...r.kernel.org Subject: [PATCH AUTOSEL 4.9 68/90] dt-bindings: sound: wm8994: Correct required supplies based on actual implementaion From: Krzysztof Kozlowski <krzk@...nel.org> [ 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>).
