From: Takeshi Kihara <takeshi.kihara.df@renesas.com>
This patch adds CAN{0,1} controller nodes for the R8A77965 SoC.
Based on several similar patches of the R8A7795 device tree
by Ramesh Shanmugasundaram <ramesh.shanmugasundaram@bp.renesas.com>
and Geert Uytterhoeven <geert+renesas@glider.be>.

Why seperate patches for CAN and CANFD here while they are merged for
r8a77990 into one patch?

Because they are two different IP blocks, but I can merge the patches
together if that's what you want.

Merging these patches makes sense to me.

Were you able to do some testing using EXIO connectors? Would be nice to
know what was tested.

Not on the M3N, since I don't see it broken out on the EXIO ; is it
really there ? It'd be easy to test on M3NSK with KF, but I don't have
either KF or M3NSK.
