This patch fixes a limitation in case of multiple enable pin usages.
Several regulators can be enabled/disabled at the same time by one
shared GPIO pin.
If specific GPIO pin is already used, then skip requesting the GPIO.

When a regulator is enabled or disabled, enable GPIO state is changed if it is
used.
If multiple regulators are controlled by one shared GPIO, pin states of other
GPIOs should be updated also.
Look up the list of regulators and change the enable pin state if same GPIO

Commit cc2383ec06be093789469852e1fe96e1148e9a2c (mm: introduce
arch-specific vma flag VM_ARCH_1) merged in v3.7-rc1.
The above commit combined several arch-specific vma flags into one, and
in the process it changed the VM_GROWSUP definition to depend on
specific architectures rather than
Add [!]METAG to a couple of Kconfig dependencies in lib/Kconfig.debug.
Don't allow stack utilization instrumentation on metag, and allow
building with frame pointers.

Commit 09f6ffde introduced a dependency on USB_EHCI_HCD for the chipidea
USB host driver, that in turns depends on USB_ARCH_HAS_EHCI.
If this symbol is not set for MXS, the MXS boards are not able to use the
chipidea driver anymore.

Add basic metag documentation. This includes an outline description of
the ABIs (including syscall ABI) and calling conventions, similar to the
one in Documentation/frv/.

Add header files to implement Meta hardware thread locks (used by some
other atomic operations), atomics, spinlocks, and bitops.
There are 2 main types of atomic primitives for metag (in addition to
IRQs off on UP):
- LOCK instructions provide locking between hardware threads.
- LNKGET/LNKSET
Add time keeping code for metag. Meta hardware threads have 2 timers.
The background timer (TXTIMER) is used as a free-running time base, and
the interrupt timer (TXTIMERI) is used for the timer interrupt. Both
counters traditionally count at approximately 1MHz.

Add trap code for metag. At the lowest level Meta traps (and return from
interrupt instruction - RTI) simply swap the PC and PCX registers and
optionally toggle the interrupt status bit (ISTAT). Low level TBX code

number based on
Add metag system call and gateway page interfaces. The metag
architecture port uses the generic system call numbers from
asm-generic/unistd.h, as well as a user gateway page mapped at
0x6000 which contains fast atomic primitives (depending on SMP) and
a fast method of accessing TLS data.
Add signal handling code for metag.
