From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Tue, 16 Feb 2010 05:17:52 +0000 Subject: [PATCH] sh: fix sh7722 SDHI support using INTC force_disable Message-Id: <20100216051752.6966.30761.sendpatchset@t400s> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm Update the sh7722 INTC tables with force_enable support to mask out pending unsupported SDHI interrupt sources. Without this patch the kernel locks up due to a pending SDHI interrupt that the tmio_mmc driver cannot handle.
