Subject: [PATCH 1/5] ASoC: codecs: ad193x: Remove capture support for codecs without ADC
Date: Mon, 18 Feb 2019 16:10:28 +0000 [thread overview]
Message-ID: <20190218160954.13929-2-codrin.ciubotariu@microchip.com> (raw)
In-Reply-To: <20190218160954.13929-1-codrin.ciubotariu@microchip.com>
From: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>
Some ad193x codecs don't have ADCs, so they have no capture capabilities.
This way, we can use this driver in multicodec cards.
