Hi Akash, Jagan,
Looks like USB is not functional in u-boot on Rockpro64. u-boot is
from git, commit 680023c5fab6b1777c0c6f2e76e5d2effb7903a0.
I'm using u-boot SPL and mainline ATF
(19adcb415c313d656324d54e7608cdc7d7a5c414 is ATF commit)
'usb start' doesn't detect anything but hubs and looks like there's no
power on USB ports:

Any ideas what can be wrong? Have it worked before?

I remember my last checking, give me sometime will check it on master
and update you.

Looks like gpio clock is not enabled anywhere in u-boot for rk3399, so
gpios just don't work.
rk3399 clock driver is very rudimentary and doesn't touch clock gates at all.
Can anyone explain how it's supposed to work?

I was wrong about clock, it appears that set bin in CRU is disabled
clock. Yet GPIOs don't work in u-boot, e.g.
=> gpio set 154
gpio: pin 154 (gpio 154) value is 1
Warning: value of pin is still 0
154 is vcc5v0-host-regulator.gpio.

I checked voltage on regulator enable pin and it's 1.5v in u-boot (and it's
not enough to enable regulator!) and in linux it's 3v. That's why USB
ports have no power in u-boot.
Looks like u-boot doesn't switch GPIO voltage from 1.8v to 3.3v. Any
ideas how to fix this?

I think I need to clock look of this, will look into it next week. I'm
travelling till that time.

I figured it out, rockpro64 needs I/O domains to be configured in
order for USB to work.
See "rockchip: rk3399: split rockpro64 out of evb_rk3399" patch on ML.
