From 6de0b0292b548010b09917e8cdfc337a6dcf67ce Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Thu, 22 Sep 2022 11:59:12 +0200 Subject: [PATCH] ASoC: es8316: fix register sync error in suspend/resume tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The SOF CI tests report failures with the following error thrown kernel: es8316 i2c-ESSX8336:00: Unable to sync registers 0x0-0x1. -121 ES8336 only supports I2C read/write one byte a time, so we do need to set the .use_single_read and .use_single_write flags to avoid this sync issue.
