been done by U-Boot. This allows the USB to work when we load the kernel
directly.
No dma sync is performed after these operations as the data we read/write
is not used by the cpu after the calls to the maimbox driver.

- Implement support for interrupt filters in the DWC OTG driver, to
reduce the amount of CPU task switching when only feeding the FIFOs.
- Add common spinlock to the USB bus structure.

- Rework how we allocate and free USB host channels, so that we only
allocate a channel if there is a real packet going out on the USB
cable.
- Use BULK type for control data and status, due to instabilities in
the HW it appears.
- Split FIFO TX levels into one for the periodic FIFO and one for the
non-periodic FIFO.
- Use correct HFNUM mask when scheduling host transactions. The HFNUM
register does not count the full 16-bit range.
- Correct START/COMPLETION slot for TT transactions. For INTERRUPT and
ISOCHRONOUS type transactions the hardware always respects the ODDFRM
bit, which means we need to allocate multiple host channels when
processing such endpoints, to not miss any so-called complete split
opportunities.
- When doing ISOCHRONOUS OUT transfers through a TT send all data
payload in a single ALL-burst. This deacreases the likelyhood for
isochronous data underruns.
- Fixed unbalanced unlock in case of "dwc_otg_init_fifo()" failure.
- Increase interrupt priority.

to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.
Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

generic one as it appears to work
for rk3188 SoC based board too.
