Subject: [PATCH] ASoC: rsnd: dma: fix SSI9 4/5/6/7 busif dma address
Date: Fri, 22 Feb 2019 09:23:23 +0100	[thread overview]
Message-ID: <1550823803-32446-1-git-send-email-twischer@de.adit-jv.com> (raw)

From: Jiada Wang <jiada_wang@mentor.com>

Currently each SSI unit 's busif dma address is calculated by
following calculation formulation:
0xec540000 + 0x1000 * id + busif / 4 * 0xA000 + busif % 4 * 0x400

But according to user manual 41.1.4 Register Configuration
ssi9 4/5/6/7 busif data register address
(SSI9_4_BUSIF/SSI9_5_BUSIF/SSI9_6_BUSIF/SSI9_7_BUSIF)
are out of this rule.

This patch updates the calculation formulation to correct
ssi9 4/5/6/7 busif data register address

Fixes: commit 5e45a6fab3b9 ("ASoc: rsnd: dma: Calculate dma address with consider of BUSIF")
