Subject: [PATCH] ASoC: rt5645: reset RT5645_AD_DA_MIXER at probe
Date: Wed, 22 Nov 2017 13:59:19 +0800 [thread overview]
Message-ID: <1511330359-20702-1-git-send-email-bardliao@realtek.com> (raw)
RT5645_AD_DA_MIXER (0x29) register will not be reset to default after
SW reset. So we have to write it to its default value in i2c_probe.
