[v2] Add support for Renesas RZ/V2N SoC and EVK

[PATCH v2 03/12] dt-bindings: soc: renesas: Document SYS for RZ/V2N SoC

Posted by Prabhakar 8 months, 2 weeks ago

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Add the RZ/V2N (R9A09G056) variant to the existing RZ/V2H(P) System
Controller (SYS) binding, as both IPs are very similar.

However, they have different SoC IDs, and the RZ/V2N does not have
PCIE1 configuration registers, unlike the RZ/V2H(P) SYS IP. To handle
these differences, introduce a new compatible string
`renesas,r9a09g056-sys`.

i.e. will queue in renesas-devel for v6.16.
