ROHM BD71828 PMIC contains 4 pins which can be configured by OTP to be used for general purposes. First 3 can be used as outputs and 4.th pin can be used as input. Allow them to be controlled via GPIO framework. The driver assumes all of the pins are configured as GPIOs and trusts that the reserved pins in other OTP configurations are excluded from control using "gpio-reserved-ranges" device tree property (or left untouched by GPIO users). Typical use for 4.th pin (input) is to use it as HALL sensor input so that this pin state is toggled when HALL sensor detects LID position change (from close to open or open to close). PMIC HW implements some extra logic which allows PMIC to power-up the system when this pin is toggled. Please see the data sheet for details of GPIO options which can be selected by OTP settings.

Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages. The parsing functions can be re-used by other ROHM chip drivers like bd71828. Split the generic functions from bd718x7-regulator.c to rohm-regulator.c and export them for other modules to use.

Posix requires that file permissions be checked on open and nowhere else. Orangefs-through-the-kernel needs to seem posix compliant. The VFS opens files, even if the filesystem provides no method. We can see if a file was successfully opened for read and or for write by looking at file->f_mode. When writes are flowing from the page cache, file is no longer available. We can trust the VFS to have checked file->f_mode before writing to the page cache. The mode of a file might change between when it is opened and IO commences, or it might be created with an arbitrary mode. We'll make sure we don't hit EACCES during the IO stage by using UID 0" [ This is "posixish", but not a great solution in the long run, since a proper secure network server shouldn't really trust the client like this.

pipe_wait() may be simple, but since it relies on the pipe lock, it means that we have to do the wakeup while holding the lock. That's unfortunate, because the very first thing the waked entity will want to do is to get the pipe lock for itself. So get rid of the pipe_wait() usage by simply releasing the pipe lock, doing the wakeup (if required) and then using wait_event_interruptible() to wait on the right condition instead. wait_event_interruptible() handles races on its own by comparing the wakeup condition before and after adding itself to the wait queue, so you can use an optimistic unlocked condition for it.
