Subject: [PATCH 07/16] ASoC: sun4i-i2s: Fix sun8i volatile regs
Date: Sat,  4 Jul 2020 13:38:53 +0200	[thread overview]
Message-ID: <20200704113902.336911-8-peron.clem@gmail.com> (raw)
In-Reply-To: <20200704113902.336911-1-peron.clem@gmail.com>

The FIFO TX reg is volatile and sun8i i2s register
mapping is different from sun4i.

Even if in this case it's doesn't create an issue,
Avoid setting some regs that are undefined in sun8i.
