Davis" Subject: [alsa-devel] [PATCH 05/17] ASoC: tlv320aic31xx: Switch GPIO handling to use gpiod_* API X-BeenThere: alsa-devel@alsa-project.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: "Alsa-devel mailing list for ALSA developers - http://www.alsa-project.org" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org X-Virus-Scanned: ClamAV using ClamSMTP Move to using newer gpiod_* GPIO handling functions. This simplifies the code and eases dropping platform data in the next patch. Also remember GPIO are active low, so set "1" to reset. Signed-off-by: Andrew F.
