Changes since v1:
Bay Trail / BYT SoCs do not have a builtin device-mode phy, instead
they require an external ULPI phy for device-mode.
Only some BYT devices have an external phy, but even on those devices
device-mode is not working because the dwc3 does not see the phy.
The problem is that the ACPI fwnode for th
Even though we only use them once, it is better to not put/release
the GPIOs immediately after use, so that others cannot claim them.
Use devm functions to get the phy GPIOs, so that they will be
automatically released when were unbound from the device and
remove the gpio_put calls.

On some Bay Trail (BYT) systems the firmware does not enable the
ULPI Refclk.
This commit adds a helper which checks and if necessary enabled the Refclk
and calls this helper for BYT machines.

Hello
Sorry for the delay. I've briefly tested the changes and so far have
not encountered the issue anymore - due to the nature of it, it could
just coincidentally not be occurring anymore, though I suspect it would
have occurred some time by now.
Thanks!

There is no timeout limit mentioned in xhci specification so

Hi All,
While testing usb-next on some Intle Bay and Cherry Trail
devices I noticed the following new error in my logs:

This is caused by the new clk_bulk_get() call in
