Subject: [PATCH] sh: export the sh7343 JPU to user space
Date: Thu, 25 Dec 2008 09:55:26 +0000 [thread overview]
Message-ID: <20081225095526.32515.83316.sendpatchset@rx1.opensource.se> (raw)
From: Magnus Damm <damm@igel.co.jp>
This patch exports the sh7343 JPU to user space using uio_pdrv_genirq,
very similar to the sh7722 JPU patch by Hayama-san.
While at it fix up the end of the sh7722 JPU iomem resource.
