[PATCH 5.10.y-cip 15/24] dt-bindings: pinctrl: renesas: Document RZ/V2L pinctrl


Biju Das
 

commit c07b19de2f7ac91662aa99767815a258da6ef16f upstream.

Document Renesas RZ/V2L pinctrl bindings. The RZ/V2L SoC is package-
and pin-compatible with RZ/G2L. No driver changes are required as the
RZ/G2L compatible string "renesas,r9a07g044-pinctrl" will be used as a
fallback.

+ The Renesas SoCs of the RZ/{G2L,V2L} series feature a combined Pin and GPIO
controller.
Pin multiplexing and GPIO configuration is performed on a per-pin basis.
Each port features up to 8 pins, each of them configurable for GPIO function
