Video engine in AST2600 has the exactly same register set with
AST2500 except VR084 register which provides more precise JPEG
size read back. This commit adds support for the difference and
adds 'aspeed,ast2600-video-engine' compatible OF string.

Thanks for your review!
Did you post an update to the device tree bindings too?
Device tree bindings and aspeed-g6.dtsi change were merged in
'next-20200225' tag already.
Thanks,
Jae
