Message-Id: <1420608947-6861-1-git-send-email-nobuhiro.iwamatsu.yj@renesas.com> Date: Wed, 7 Jan 2015 14:35:47 +0900 From: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@...esas.com> To: netdev@...r.kernel.org Cc: yoshihiro.shimoda.uh@...esas.com, linux-sh@...r.kernel.org, Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@...esas.com> Subject: [PATCH] sh_eth: Fix access to TRSCER register TRSCER register is configured differently by SoCs. TRSCER of R-Car is RINT8 bit only valid, other bits are reserved bits. This removes access to TRSCER register reserve bit.
