Subject: [PATCH v6 5/7] ASoC: sun4i-i2s: Add functions for RX and TX channel mapping
Date: Wed, 16 Oct 2019 09:07:38 +0200 [thread overview]
Message-ID: <20191016070740.121435-6-codekipper@gmail.com> (raw)
In-Reply-To: <20191016070740.121435-1-codekipper@gmail.com>
From: Marcus Cooper <codekipper@gmail.com>
As we will eventually add multi-channel audio support to the i2s
then create function calls as opposed to regmap fields to add
support for different devices.
