[v4,1/3] media: dt-bindings: media: renesas,vsp1: Document RZ/{G2L,V2L} VSPD bindings
Commit Message
Document VSPD found in RZ/G2L and RZ/V2L family SoC's. VSPD block is
similar to VSP2-D found on R-Car SoC's, but it does not have a version
register and it has 3 clocks compared to 1 clock on vsp1 and vsp2.
This patch introduces a new compatible 'renesas,rzg2l-vsp2' to handle
these differences.
