Hello.
USB functionality on PCM038 (PCM970) is broken again due
patch "Revert usb: chipidea-imx: Fix usb initialization".

Have you verified it really doesn't work? I get the 'No ULPI found'
message aswell, but the ULPI phys are probed again during the 'usb'
command and it then works here.

Same result on CCMX51.

And yes, this works after "usb" command:
barebox@ConnectCore i.MX51:/ usb
USB: scanning bus for devices...
Found NXP ISP150x ULPI transceiver (0x04cc:0x1504).

So, you consider this is not a bug?

Doing the initialization twice is not nice and wasn't intended, so
indeed this is something worth fixing.

Datasheet MCIMX51RM.pdf says:
60.3.8 ULPI/Serial MUX
Host1, Host2, and OTG cores can be configured by software for ULPI or Serial PHY operation. The
ULPI/Serial mux selects between ULPI interface signals and Serial PHY interface signals. The mux is
controlled by the PHY Select signals from the USB core and is switched when the software selects the
interface mode.
The default configuration for the mux is Serial mode. Switching to ULPI mode is done by writing the
Parallel Transceiver Select (PTS) bits in the PORTSC register with 0b10.
So, we need to setup PORTSC to ULPI mode first.

Yes, ok. The problem is that fixing initialization on one board seems
to break it on another board. I'm a bit out of ideas since this
initialization shuffeling follows me for several years now. I have some
patches in my queue which I'll send the weekend. I hope this fixes it
for you while keeping HSIC workable.
