Subject: [PATCH v5 08/15] ASoC: sun4i-i2s: Add functions for channel mapping
Date: Wed, 14 Aug 2019 08:08:47 +0200 [thread overview]
Message-ID: <20190814060854.26345-9-codekipper@gmail.com> (raw)
In-Reply-To: <20190814060854.26345-1-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.
