From 523fc35e81f48fd735b52be3574cb417cad4413c Mon Sep 17 00:00:00 2001 From: YR Yang Date: Thu, 1 Aug 2024 16:43:26 +0800 Subject: [PATCH] ASoC: mediatek: mt8188: Mark AFE_DAC_CON0 register as volatile BugLink: https://bugs.launchpad.net/bugs/2087519 [ Upstream commit ff9f065318e17a1a97981d9e535fcfc6ce5d5614 ] Add AFE Control Register 0 to the volatile_register. AFE_DAC_CON0 can be modified by both the SOF and ALSA drivers. If this register is read and written in cache mode, the cached value might not reflect the actual value when the register is modified by another driver. It can cause playback or capture failures. Therefore, it is necessary to add AFE_DAC_CON0 to the list of volatile registers.
