[PATCH v6 1/4] dt-bindings: can: renesas,rcar-canfd: Simplify renesas,no-can-fd description

From: Biju Das

Date: Wed Oct 21 2026 - 04:36:09 EST


The description of renesas,no-can-fd lists the operating modes
(CAN-FD, FD-Only and Classical CAN) and which SoCs support each one.
This is not accurate for every supported SoC, for example RZ/G3S, whose
CAN-FD controller has no Classical CAN mode.

Drop the mode list and keep only the statement of what the property
does, so the description no longer implies that all SoCs can operate in
Classical CAN mode.
