Subject: [PATCH v5 05/15] ASoC: sun4i-i2s: Add functions for RX and TX channel offsets
Date: Wed, 14 Aug 2019 08:08:44 +0200 [thread overview]
Message-ID: <20190814060854.26345-6-codekipper@gmail.com> (raw)
In-Reply-To: <20190814060854.26345-1-codekipper@gmail.com>
From: Marcus Cooper <codekipper@gmail.com>
Newer SoCs like the H6 have the channel offset bits in a different
position to what is on the H3. As we will eventually add multi-
channel support then create function calls as opposed to regmap
fields to add support for different devices.
