Hi Hans,
with these regulators USB works on the Orange Pi Plus too.
I don't know if adding the regulators in the dts is okay, since most
regulators are defined in the sunxi-common-regulators.dtsi, but
we use different pins.

I've been trying to test these patches by using Hans' github sunxi-wip
branches of the kernel and U-Boot.
U-Boot at commit 7e17fd2 "suxni: Add support for Orangepi Plus and Orangepi
PC boards"
Kernel at commit cb45b8 "ARM: dts: sun8i-h3-orangepi-plus: Enable USB host
controllers"
Both have been built using the default defconfig for an OrangePi Plus
U-Boot starts and successfully boots the kernel, but the kernel does not
appear to boot fully and hangs at:
[ 0.861175] cpu cpu0: failed to get cpu0 clock: -2
[ 0.865973] cpufreq-dt: probe of cpufreq-dt failed with error -2
[ 0.872017] Registering SWP/SWPB emulation handler
Full boot log: http://pastebin.com/VGkEix9p
Building the kernel (or just using a dab) with the dts from commit 0a8c01
"ARM: dts: sun8i: Add Orange Pi Plus support" results in the kernel booting
fully to a login prompt. Of course without enabled/working USB.
There is a fair chance I've done something wrong that is causing this. Any
advice on how to get a bootable kernel?
Weird, are you sure you updated both the dtb and [u|z]image at the same time ?
I'm using this kernel config:
https://fedorapeople.org/~jwrdegoede/kernel-driver-programming/kernel-config
With that everything you need is builtin, no need to build modules.
Regards,
Hans
