Dear All,
I am reposting some CAN and CANFD related dt-bindings changes for
Renesas' R-Car and RZ/G devices that have been originally sent
end of last year and beginning of this year.
Thanks,
Fab

Dave,
are you comfortable with me taking these patches
through the renesas tree? Or perhaps should they be reposted
to you for inclusion in net-next?
They have been stuck for a long time now.
