From 716293381a0f9a400d0010628a9ba4354c2bea40 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 1 Sep 2023 14:00:55 +0200 Subject: [PATCH] dt-bindings: power: syscon-poweroff: get regmap from parent node Just like syscon-reboot device, the syscon-poweroff is supposed to be a child of syscon node, thus we can take the same approach as syscon-poweroff: deprecate the 'regmap' field in favor of taking it from the parent's node.
