Subject: [PATCH v4 07/07] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
Date: Wed, 08 Jun 2016 16:18:43 +0900	[thread overview]
Message-ID: <20160608071843.7560.72573.sendpatchset@little-apple> (raw)
In-Reply-To: <20160608071737.7560.32571.sendpatchset@little-apple>

From: Magnus Damm <damm+renesas@opensource.se>

Neither the ARM page table code enabled by IOMMU_IO_PGTABLE_LPAE
nor the IPMMU_VMSA driver actually depends on ARM_LPAE, so get
rid of the dependency.

Tested with ipmmu-vmsa on r8a7794 ALT and a kernel config using:
 # CONFIG_ARM_LPAE is not set

Signed-off-by: Magnus Damm <damm+renesas@opensource.se>
Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

 Changes since V3:
 - None

 Changes since V2:
 - None

 Changes since V1:
 - Rebased on top of ARCH_RENESAS change
 - Added Acked-by from Laurent
