[PATCH 5.10.y-cip 02/29] spi: dt-bindings: renesas,rspi: Document RZ/G2L SoC


Lad Prabhakar
 

commit 5a8f8542e34b6469cd5c5a3d075fa5977d90775e upstream.

Add RSPI binding documentation for Renesas RZ/G2L SoC.

RSPI block is identical to one found on RZ/A, so no driver changes are
required. The fallback compatible string "renesas,rspi-rz" will be used
on RZ/G2L.
