Date: Mon, 18 Feb 2019 16:10:30 +0000 From: <Codrin.Ciubotariu@...rochip.com> To: <lars@...afoo.de>, <lgirdwood@...il.com>, <broonie@...nel.org> CC: <alsa-devel@...a-project.org>, <linux-kernel@...r.kernel.org>, <Codrin.Ciubotariu@...rochip.com> Subject: [PATCH 2/5] ASoC: codecs: ad193x: Set constraint to always have 32 sample bits From: Codrin Ciubotariu <codrin.ciubotariu@...rochip.com> DACs and ADCs on ad193x codecs require a 32 bit slot size. We should assure that no other size is used.
