This patch adds support for the PLX USB3380 and USB3382.
This driver is based on the driver from the manufacturer.
Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.
Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.
This patch has only been tested on USB338x hardware, but the merge has
been done trying to not affect the behaviour of NET2280.

Newer DWC3 controllers can be built for USB 2.0-only mode, where
most of the USB 3.0 circuitry is left out. To support this mode,
the driver must limit the speed programmed into the DCFG register
to Hi-Speed or lower.
Reads and writes to the PIPECTL register are left as-is, since
they should be no-ops in USB 2.0-only mode. Calls to phy_init()
etc. for the USB3 phy are also left as-is, since the no-op USB3
phy should be used for USB 2.0-only mode controllers.

The various devm_ functions allocate memory that is released when a
driver detaches. This patch uses devm_kzalloc, devm_request_irq,
devm_gpio_request, devm_regulator_get etc. for data that is
allocated in the probe function of a platform device and is only
freed in the remove function. The corresponding free functions are
removed and the labels are done away with.

Pull ARM fixes from Russell King:
"Another round of ARM fixes. The largest change here is the L2 changes
to work around problems for the Armada 37x/380 devices, where most of
the size comes down to comments rather than code.
The other significant fix here is for the ptrace code, to ensure that
rewritten syscalls work as intended. This was pointed out by Kees
Cook, but Will Deacon reworked the patch to be more elegant.
The remainder are fairly trivial changes"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8087/1: ptrace: reload syscall number after secure_computing() check
ARM: 8086/1: Set memblock limit for nommu
ARM: 8085/1: sa1100: collie: add top boot mtd partition
ARM: 8084/1: sa1100: collie: revert back to cfi_probe

On the syscall tracing path, we call out to secure_computing() to allow
seccomp to check the syscall number being attempted. As part of this, a
SIGTRAP may be sent to the tracer and the syscall could be re-written by
a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall
is ignored by the current code unless TIF_SYSCALL_TRACE is also set on
the current thread.
This patch slightly reworks the enter path of the syscall tracing code
so that we always reload the syscall number from
current_thread_info()->syscall after the potential ptrace traps.
