Date: Sun, 9 Aug 2020 12:17:45 +0100 Message-Id: <20200809111753.156236-6-jic23@kernel.org> X-Mailer: git-send-email 2.28.0 In-Reply-To: <20200809111753.156236-1-jic23@kernel.org> References: <20200809111753.156236-1-jic23@kernel.org> MIME-Version: 1.0 Sender: devicetree-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: devicetree@vger.kernel.org From: Jonathan Cameron Simple conversion for this ADC driver. Note that I haven't put limits on the spi-max-sampling-frequency because the adc161s626 doesn't state one clearly defined value. Added the #io-channel-cells property to allow for consumers.
