*	iommu: drop owner assignment from platform_drivers	Wolfram Sang	2014-10-20	1	-1/+0
\| \| \| \| \| \| \|	A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
*	iommu/shmobile: Use devm_ioremap_resource()	Laurent Pinchart	2014-04-17	1	-11/+6
\| \| \| \| \| \| \|	Replace the devm_ioremap_nocache() call with devm_ioremap_resource(). This simplifies error checking. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
*	iommu/shmobile: Don't ignore the ipmmu_iommu_init() return value	Laurent Pinchart	2014-04-17	1	-2/+1
\| \| \| \| \| \|	The function can fail, don't ignore its error value. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
*	iommu/shmobile: Turn the flush_lock mutex into a spinlock	Laurent Pinchart	2014-01-07	1	-5/+5
\| \| \| \| \| \| \|	The lock is taken in atomic context, replace it with a spinlock. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>
*	iommu/shmobile: Add iommu driver for Renesas IPMMU modules	Hideki EIRAKU	2013-02-06	1	-0/+136
	This is the Renesas IPMMU driver and IOMMU API implementation. The IPMMU module supports the MMU function and the PMB function. The MMU function provides address translation by pagetable compatible with ARMv6. The PMB function provides address translation including tile-linear translation. This patch implements the MMU function. The iommu driver does not register a platform driver directly because: - the register space of the MMU function and the PMB function have a common register (used for settings flush), so they should ideally have a way to appropriately share this register. - the MMU function uses the IOMMU API while the PMB function does not. - the two functions may be used independently.
