Subject: [PATCH] ASoC: ak4642: Implement suspend callback
Date: Tue, 31 May 2016 13:14:30 +0300 [thread overview]
Message-ID: <20160531101430.14396-1-peter.ujfalusi@ti.com> (raw)
Add the suspend callback to accompany the existing resume operation.
With the suspend/resume callbacks the regmap (regcache) state handling can
follow the recommended sequence.
