Subject: [PATCH v1 3/6] ASoC: sgtl5000: Fix of unmute outputs on probe
Date: Tue, 21 May 2019 13:36:16 +0300	[thread overview]
Message-ID: <20190521103619.4707-4-oleksandr.suvorov@toradex.com> (raw)
In-Reply-To: <20190521103619.4707-1-oleksandr.suvorov@toradex.com>

To enable "zero cross detect" for ADC/HP, change
HP_ZCD_EN/ADC_ZCD_EN bits only instead of writing the whole
CHIP_ANA_CTRL register.
