Subject: Re: [PATCH v2 1/2] ARM: dts: rockchip: add rga node for rk322x

Hi Justin,

rga is now inserted above vpu_mmu.
Please check the address.

rga:       rga@...60000 {
vpu_mmu: iommu@...20800 {

Should go between vop_mmu and iep_mmu.

vop_mmu: iommu@...53f00 {
rga:       rga@...60000 {
iep_mmu: iommu@...70800 {
