[PATCH v2 0/2] arm64: dts: renesas: Add CAN-FD support for R-Car V4M and Gray Hawk Single

[Geert Uytterhoeven]

	Hi all,

This patch series adds support for CAN-FD on the R-Car V4M SoC and the
Gray Hawk Single development board.

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).

Just like on R-Car V4H and on the White Hawk development board, channels
0 and 1 work fine, while channel 2 does not seem to work at all, and
channel 3 works for transmit only.  Hence this patch keeps channels 2
and 3 disabled.

Changes compared to v1[1]:
  - Spun off clock and DT binding patches,
  - Add missing pinctrl-names,
  - Correct TJR1443AT Enable GPIO,
  - Reword now channels 0 and 1 work.

I plan to queue this is renesas-devel for v6.12.

Thanks for your comments!
