Subject: [PATCH AUTOSEL 5.4 10/24] ASoC: cs42l42: Fix Bitclock polarity inversion
Date: Thu, 25 Mar 2021 07:26:36 -0400	[thread overview]
Message-ID: <20210325112651.1927828-10-sashal@kernel.org> (raw)
In-Reply-To: <20210325112651.1927828-1-sashal@kernel.org>

From: Lucas Tanure <tanureal@opensource.cirrus.com>

[ Upstream commit e793c965519b8b7f2fea51a48398405e2a501729 ]

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.
