Date: Sun, 3 May 2020 19:14:45 +0200 Message-Id: <20200503171451.44034-1-contact@artur-rojek.eu> X-Mailer: git-send-email 2.26.2 MIME-Version: 1.0 Sender: linux-input-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-input@vger.kernel.org Convert the textual documentation of Device Tree bindings for the Ingenic JZ47xx SoCs ADC controller to YAML. The `interrupts` property is now explicitly listed and marked as required. While missing from the previous textual documentation, this property has been used with all the boards which probe this driver.
