Subject: [PATCH v6 07/07] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
Date: Thu, 20 Oct 2016 08:36:43 +0900 [thread overview]
Message-ID: <20161019233643.10506.46839.sendpatchset@little-apple> (raw)
In-Reply-To: <20161019233533.10506.16810.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>
