[PATCH v3 0/2] Add rga to rk322x device tree

[Justin Swartz]

This patchset aims to enable use of Rockchip's RGA, a 2D raster
graphic acceleration unit, on rk322x based devices.

Changed in v3:
  - Relocate rga node to the correct position in rk322x.dtsi, as
    indicated by Johan Jonker.

Changes in v2:
  - Remove unnecessary "rockchip,rk3228-rga" device tree compatibility
    string patch, as advised by Ezequiel Garcia.

  - Use both "rockchip,rk3228-rga" and "rockchip,rk3288-rga" in the
    rga node's compatibility property, as suggested by Heiko Stuebner.

Why's that? You're using the string still, it needs to be documented.

Unless you need to tune something in the driver
specifically for rk3228, then you don't need a
new compatible string.

As the name implies, it's just a "compatible",
so you may simply declare your rga dts node as
compatible to "rockchip,rk3288-rga".

(Of course, this means we shouldn't have added
the rk3399 compatible string.)

Ezequiel

small correction, we normally do that in two parts in the dts,
	compatible = "rockchip,rk3228-rga", "rockchip,rk3288-rga"

etc. So the compatible needs to be added to binding document but
not necessarily to the driver but does leave us the option of later
defining that new compatible in the driver to handle quirks that may
be discovered later on, without needing to adapt existing devicetrees.

Hi Justin,

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

rga:       rga@20060000 {
vpu_mmu: iommu@20020800 {

Should go between vop_mmu and iep_mmu.

vop_mmu: iommu@20053f00 {
