please split this into
- patch adding the dtsi

I'd think we'll want a
	stdout-path = something
property here, instead of hard-coding bootargs.

same as Rob said for the ramoops, I don't see this one in the devicetree 
bindings. Also gt9xx should instead specify an actual chip, not a chip-family.
See drivers/input/touchscreen/goodix.c and 
Documentation/devicetree/bindings/input/touchscreen for supported chips and 
the real devicetree bindings.

not 100% sure, but we might want a
		compatible = "rockchip,rk3399-sdhci-5.1", "arasan,sdhci-5.1";

allowing us to get more specific, if implementation oddities surface later.

this doesn't look like it got submitted yet.

Also, the newer socs (rk3399. rk3036, rk3228) seem to use a different usbphy 
block than rk3288 and before (with a big bunch of new phy-related register 
blocks I haven't looked at yet) - so this should probably get a new driver as 
well and not be crammed into the current phy driver, which is for the older 
picophy (or what it was called).

When we're doing a new driver, could we please get rid of these subnodes and 
instead access phys via something like

	phys = <&usb2phy 0>;

mali kernel-part is out-of-tree code with a unreviewed binding, so should not

I think the hotplug detection is pretty optional, so should live in the board
