This adds the gpio-ranges property to pm8941_gpios so that the GPIO
pins are initialized by the GPIO framework and not pinctrl. This fixes
a circular dependency so GPIO hogging can be used on this board.

When attempting to setup up a gpio hog, device probing would repeatedly
fail with -EPROBE_DEFERED errors. It was caused by a circular dependency
between the gpio and pinctrl frameworks. If the gpio-ranges property is
present in device tree, then the gpio framework will handle the gpio pin
This patch set adds USB OTG support for the LG Nexus 5 (hammerhead)

Changes in v2:
- Reworked patches to use gpio hogging as suggested in the bq24190

by Sebastian Reichel.

ldsem_down_read() will sleep if there is pending writer in the queue.
If the writer times out, readers in the queue should be woken up,
otherwise they may miss a chance to acquire the semaphore until the last

Make sure under CONFIG_LOCKDEP that each change to line discipline
is done with held write semaphor.
Otherwise potential reader will have a good time dereferencing

An exception here is tty_ldisc_open(), as it's called without ldisc_sem

It seems like when ldsem_down_read() fails with timeout, it misses
update for sem->wait_readers. By that reason, when writer finally
