Subject: [PATCH v2 01/15] ASoC: cs42l42: Fix Bitclock polarity inversion
Date: Fri, 5 Mar 2021 17:34:28 +0000	[thread overview]
Message-ID: <20210305173442.195740-2-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20210305173442.195740-1-tanureal@opensource.cirrus.com>

The driver was setting bit clock polarity opposite to intended polarity.
Also simplify the code by grouping ADC and DAC clock configurations into
a single field.
