Subject: [PATCH v3 04/12] ASoC: sun4i-i2s: Add TX FIFO offset to quirks

From: [email-masked] (codekipper at gmail.com)
Date: Sat, 29 Jul 2017 16:17:45 +0200

From: Marcus Cooper <[email-masked]>

It has been seen that the newer SoCs have a different TX FIFO
address. Add this to the quirks structure.
