Ok, ill switch to the usual way here..

In RZ/Five HW manual this is documented as LEVEL_HIGH and RZ/G2UL this
is documented as EDGE. I ve internally asked for clarification with
the HW team. If it's the same for both the SoCs I'll move this node to
common SoC dtsi and just update the compat string in rz/five specific
dtsi.

Cheers,
Prabhakar
