[PATCH v1 0/2] userspace-consumer: adding is_shared flag

[Daniel Okazaki <dtokazaki@google.com>]

Hi,

Currently this userspace regulator driver requires exclusive control
of the regulator to operate. This patch adds an optional flag to
remove that constraint, and allow the regulator to be shared by other
modules. This allows for userspace to share control over a regulator
with kernel space.

There is a boot time behavior change when this flag is set.
Before, if the gpio was enabled before this driver probes, it would
stay enabled. This change allows regulator_init_complete_work
to disable the regulator on completion.

The regulator state reported by this driver is changed from the
absolute state to the local state of the driver. This abstracts
away the regulator state of other consumers from this driver.
