sh: export the sh7343 JPU to user space
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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
