Subject: [PATCH v2 3/7] ASoC: sun4i-codec: Add support for different DAC FIFOC addresses to quirks
Date: Sun, 20 Oct 2024 21:30:53 +1300	[thread overview]
Message-ID: <20241020083124.174724-4-ryan@testtoast.com> (raw)
In-Reply-To: <20241020083124.174724-1-ryan@testtoast.com>

From: Marcus Cooper <codekipper@gmail.com>

The Allwinner H616 SoC  uses a different register address to control the
output FIFO.

Allow this to be specified separately from the ADC FIFO control
register.
