SATA on R-Car H3 ES2.0 works fine with the IOMMU. This is also needed for virtualization. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- For testing virtualization, this patch and all prerequisites are available in the topic/rcar3-virt-gpio-passthrough-v3 branch of my git repository at git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git. drivers/iommu/ipmmu-vmsa.c | 3 +++ 1 file changed, 3 insertions(+)
