dt-bindings: can: renesas,rcar-canfd: Document R-Car V4M support
Document support for the CAN-FD Interface on the Renesas R-Car V4M (R8A779H0) SoC, which supports up to four channels. The CAN-FD module on R-Car V4M is very similar to the one on R-Car V4H, but differs in some hardware parameters, as reflected by the Parameter Status Information part of the Global IP Version Register. However, none of this parameterization should have any impact on the driver, as the driver does not access any register that is impacted by the parameterization (except for the number of channels).
