From d10be65f87fc9d98ad3cbdc406e86745fe8c59e2 Mon Sep 17 00:00:00 2001 From: Jiada Wang Date: Tue, 22 Oct 2019 20:54:29 +0200 Subject: [PATCH] ASoC: rsnd: dma: fix SSI9 4/5/6/7 busif dma address Currently each SSI unit's busif dma address is calculated by following calculation formula: 0xec540000 + 0x1000 * id + busif / 4 * 0xA000 + busif % 4 * 0x400 But according to R-Car3 HW 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 formula to correct ssi9 4/5/6/7 busif data register address.
