Subject: [PATCH 7/9] ASoC: es8328: Support more sample formats
Date: Mon,  9 May 2016 12:24:35 +0100	[thread overview]
Message-ID: <20160509112437.8924-8-john@metanate.com> (raw)
In-Reply-To: <20160509112437.8924-1-john@metanate.com>

The values are the same for the DAC and ADC so remove the specific
values and use values with shifts.
