The existing rga node refers to the RGA2 peripheral. The RK3588

What is "existing rga node"? There is no node here. This is a patch for
bindings, so you say which hardware existing binding describes and what
are the differences against that older hardware.

contains one RGA2 core and two RGA3 cores. Both feature a similar
functionality of scaling, cropping and rotating of up to two input
images into one output image. Key differences of the RGA3 are:

- supports 10bit YUV output formats
- supports 8x8 tiles and FBCD as inputs and outputs
- supports BT2020 color space conversion
- max output resolution of (8192-64)x(8192-64)
- MMU can map up to 32G DDR RAM
- fully planar formats (3 planes) are not supported
- max scale up/down factor of 8

"differences" in meaning nothing above is supported by RGA2?
