Subject: Re: [PATCH v2 4/5] dt-bindings: soc: rockchip: grf: add compatible
 for RK3308 USB grf

Hi Tobias,

The grf serie is currently still under review. So things can change.
Must add a change log below a "---" in the commit message for rob+dt.
Maybe add a patch that fixes the reg size of "rockchip,rk3308-grf" as well?

Johan

Sort alphabetically.

Also allow usb2-phy as sub nodes name.

Heiko's sort rules:

compatible
reg
interrupts
[alphabetical]
status [if needed]

===

Sort #phy-cells below interrupt-names.


+				#phy-cells = <0>;
+				interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>;
+				interrupt-names = "linestate";
