Subject: [PATCH v5 07/07] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
Date: Tue, 20 Sep 2016 22:45:06 +0900	[thread overview]
Message-ID: <20160920134506.25470.77154.sendpatchset@little-apple> (raw)
In-Reply-To: <20160920134355.25470.93701.sendpatchset@little-apple>

From: Magnus Damm <damm+renesas-yzvPICuk2ACczHhG9Qg4qA@public.gmane.org>

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-yzvPICuk2ACczHhG9Qg4qA@public.gmane.org>
Acked-by: Laurent Pinchart <laurent.pinchart-ryLnwIuWjnjg/C1BVhZhaw@public.gmane.org>
