All phy related programming like enabling/disabling the clocks, powering
on/off the phy is taken care of by this driver. It is also used for OTG
related functionality like srp.

This also includes device tree support for usb2 phy driver and
the documentation with device tree binding information is updated.

Currently writing to control module register is taken care in this
driver which will be removed once the control module driver is in place.

The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used.  If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.

It works by reintroducing and expanding the skb_alloc_page() API to take
an skb.  If the page was allocated from pfmemalloc reserves, it is
automatically copied.  If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.

Failure to do so is not critical.  The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

The MC7710 in QMI mode does not support the vendor
specific USB requests used by this driver.  The most

The QMI mode of the Sierra Wireless MC7710 is close to
a Gobi device, and also identified as one by the
Windows drivers provided by Sony.  The serial interfaces
are the same as for any other Gobi module, but the USB
interface layout is different:

 0: DM/DIAG (also present in bootloader mode)
 2: NMEA
 3: AT-capable modem port
 8: QMI/net
 19: QMI/net (not always present)
 20: QMI/net (not always present)

Note in particular that the NMEA and AT ports are reversed
compared to a Gobi 2k+ device, and that the DM port appears
as a QDL port in bootloader mode using the same device ID.

The Sony driver also document two new devices with standard
Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode
(1199:68a4, 1199:68a8).  Adding these as well.

Lenovo Windows drivers document the USB interface layout
for a few additional Sierra Wireless devices. Adding these
while at it:
- MC7770 (1199:901b) with standard Gobi 2k+ layout
- MC7700 (0f3d:68a2) with the same layout as MC7710
- MC7750 (114f:68a2) with the same layout as MC7710
- EM7700 (1199:901c) with the same layout as MC7710
