Subject: [PATCH 1/4] dt-bindings: pinctrl: qcom,pmic-gpio: add 'gpio-reserved-ranges'
Date:   Sun,  8 May 2022 15:59:29 +0200
Message-Id: <20220508135932.132378-2-krzysztof.kozlowski@linaro.org>
In-Reply-To: <20220508135932.132378-1-krzysztof.kozlowski@linaro.org>

Precedence: bulk

'gpio-reserved-ranges' property is already used and supported by common pinctrl
bindings, so add it also here to fix warnings like:

  qrb5165-rb5.dtb: gpio@c000: 'gpio-reserved-ranges' does not match any of the regexes: '-state$', 'pinctrl-[0-9]+'
