[PATCH v5 2/2] dt-bindings: media: rockchip-vpu: Add rk3588 vdpu121 compatible string

[Jianfeng Liu]

Hi Krzysztof,

I'm sorry for my unkonwing about the kernel patching process. And I'm
sorry to let maintainers do extra work. Thank you for teaching me this.
I will do this right in future patches.

I did received a Acked-by tag from Conor in v4:
Acked-by: Conor Dooley <conor.dooley at microchip.com>

I note it here in case someone forgets this tag.
