From 64359246abe4421ad409be5b0bc9a534caa18b7d Mon Sep 17 00:00:00 2001 From: Clément Péron Date: Fri, 30 Oct 2020 15:46:40 +0100 Subject: ASoC: sun4i-i2s: Fix sun8i volatile regs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
