Nitpick, dummy question below...

.. I cannot find this new compatible node in U-Boot

$ grep -lr "renesas,rcar-gen5-i2c" doc/device-tree-bindings/
$ grep -lr "renesas,rcar-gen5-i2c" dts/upstream/
$

nor in current (v6.18-rc3) linux tree... is there already a patch
for linux, which introduces it? But is seems trivial to me, so I
am fine with it.

Thanks!

bye,
Heiko
