Date: Tue, 15 Mar 2022 09:37:23 +0100 From: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com> To: Linus Walleij <linus.walleij@...aro.org>, Bartosz Golaszewski <brgl@...ev.pl>, Rob Herring <robh+dt@...nel.org>, Krzysztof Kozlowski <krzk+dt@...nel.org>, linux-gpio@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Laurent Pinchart <laurent.pinchart@...asonboard.com>, Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com> Subject: [PATCH] dt-bindings: gpio: add common consumer GPIO lines Typical GPIO lines like enable, powerdown, reset or wakeup are not documented as common, which leads to new variations of these (e.g. pwdn-gpios). Add a common schema which serves also as a documentation for preferred naming.
