| Subject: ASoC: fsl_xcvr: clear the channel status control memory |
| |
| From: Shengjiu Wang <shengjiu.wang@nxp.com> |
| |
| [ Upstream commit 73b97d46dde64fa184d47865d4a532d818c3a007 ] |
| |
| memset_io() writes memory byte by byte with __raw_writeb() on the arm |
| platform if the size is word. but XCVR data RAM memory can't be accessed |
| with byte address, so with memset_io() the channel status control memory |
| is not really cleared, use writel_relaxed() instead. |
