A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

Probe ULPI phys during USB initialization and not during driver
probe. This lowers the pressure to have the necessary board specific
setup in place early.

This imports of_parse_phandle_with_args and of_count_phandle_with_args
from Linux OF API. The slightly different of_parse_phandles_with_args
is removed and all users are converted to reflect the API change.

To start synchronizing OF API of barebox with linux OF API, this adds
a length pointer to of_find_property. Also all current users of that
function are updated to reflect the API change.

This breaks HSIC and has no good justification why this would
be needed for ULPI.
This reverts commit 2e7d66f526.

This patch fix chipidea-imx usb initialization.
"imx_chipidea_port_init" was moved before PORTSC setup in the
commit "USB i.MX chipidea: implement post init support". This
change breaks usb function with ULPI. Patch moves port initialization
back after PORTSC setup, so it works again.

This adds USB gadget support to the i.MX chipidea driver. Basically
we have to add a register function to the fsl udc driver and call
this from the chipidea driver if device mode is selected.

Some controllers need an init hook after the USB controller is
started, so implement the post init hook for i.MX.

For proper USB function the usbmisc registers have to be initialized.
This patch adds a driver which matches for the usbmisc registers. This
driver is called from a new driver which binds to the USB ports to
configure the misc registers. After that the driver registers the EHCI
driver and an ULPI transceiver if necessary. Currently only host mode
is supported, but device support can be added later.
