Subject: [PATCH 1/2] ASoC: codecs: pcm186x: fix wrong usage of DECLARE_TLV_DB_LINEAR()
Date: Tue, 19 Feb 2019 16:15:42 +0000 [thread overview]
Message-ID: <20190219161518.1331-1-codrin.ciubotariu@microchip.com> (raw)
From: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>
According to DS, the gain is between -12 dB and 40 dB, with a 0.5 dB step.
Tested on pcm1863.
