From 2944d29d7c89573f9aa47083d105ff0243d5a125 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Myl=C3=A8ne=20Josserand?= Date: Mon, 18 Mar 2019 11:39:38 +0100 Subject: ASoC: simple-amplifier: Make gpio property optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some amplifier may not have a GPIO to control the power, but instead simply rely on the regulator to power up and down the amplifier. In order to support those setups, let's make the GPIO optional.
