[Dennis Gilmore]

Without the usbdrd_dwc3_1 node defined u-boot will throw an error and

Re: [PATCH 1/4] arm64: dts: rockchip: helios64: fixup USB setup

Hello,

I wonder if this should better be fixed in u-boot then?!

This is true for the dwc nodes, however for the usb2 nodes there are 
several that use this idiom (and even repeat the label name), see for 
example the &u2phy0 node in 
arch/arm64/boot/dts/rockchip/rk3399-rockpro64.dtsi .

In my eyes it's a bit ugly to have the two nodes as separate entities 
and on the same indentation level in the machine dts given that one is 
the parent of the other and enabling USB needs both status settings.

Best regards
Uwe

looking at that file is where I got the idea to set it up as I have
proposed, it follows the format I have submitted

I guess you didn't read exactly what I wrote and only looked at &usbdrd* 
but not &u2phy0.

Hi Uwe,

I did read what you pointed at, the issue is that is already defined in
arch/arm64/boot/dts/rockchip/rk3399.dtsi and all that is needed it to
set the status to okay and minor enablement. as DTC merges all the
snippets together they end up in the right place and doing the right
thing, the approach you took is different to all the other boards I
looked at and seemingly causes issues in u-boot. I did not get far
enough in booting to verify the state in linux as I am updating u-boot
as I go and testing using u-boots dtb for simplicty sake. It quite
likely is a bug in u-boot that it resets the system, at the same time I
do not think that doing it differently to how the other boards are
implemented is right either. There is still a lot of the hardware in
the system that is not defined in the devicetree file, including a lot
of the usb stack.

This doesn't make much sense - the usbdrd_dwc3_1 label is defined in 
rk3399.dtsi either way, and the compiled DTBs before and after are 
identical :/

If U-Boot is doing something funny with labels and symbols to give 
itself some kind of fragile dependency, that probably wants to be fixed 
in U-Boot.
