Stephen Boyd 8f49b623b9 mfd: cros_ec_dev: Add GPIO device if feature present on EC 
The ChromeOS embedded controller (EC) supports setting the state of
GPIOs when the system is unlocked, and getting the state of GPIOs in all
cases. Check for the feature support by checking for the GPIO feature
and then populate a sub-device for the gpio hardware on the EC.

Stephen Boyd 7b79740d42 dt-bindings: mfd: cros-ec: Add properties for GPIO controller 
The ChromeOS embedded controller (EC) supports setting the state of
GPIOs when the system is unlocked, and getting the state of GPIOs in all
cases. The GPIOs are on the EC itself, so the EC acts similar to a GPIO
expander. Add the #gpio-cells and gpio-controller properties to the
cros-ec binding so that other devices described in DT can get the GPIOs
on the EC.

Ricardo B. Marliere 3cb1085400 mfd: core: Constify the struct device_type usage 
Since commit aed65af1cc ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the mfd_dev_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.

Ondrej Jirman bda40bf667 mfd: rk8xx-core: Fix interrupt processing order for power key button 
Process rise event last, to avoid stuck keys when multiple interrupts
are coalesced. This can happen typically when resuming from suspend
via power key press and holding the power button for a bit too short,
so that RISE an FALL IRQ flags are set before any interrupt routine
has a chance to run.

Input subsystem will interpret it as holding down a power key for
a long time, which leads to unintended initiation of shutdown UI
on some OSes.

Instead of only accepting the ti specific properties accept also
the standard property. For uniformity, search in the parent node
for the tag. The code for powering off is also isolated from the
rest in this file. So it is a pure Linux design decision to put it
here.

Maciej Strozek efe4c7908e mfd: wm831x: Remove redundant forever while loop 
Current code executes only once despite the while loop, so remove the
loop. Also msleep(1) will likely result in a larger sleep, so increase
its value for clarity while keeping the same behaviour.

Simon Horman 944e823d73 mfd: rave-sp: Avoid unnecessary use of comma operator 
Although it does not seem to have any untoward side-effects,
the use of ';' to separate to assignments seems more appropriate than ','.

No functional change intended. Compile tested only.

misconfigured clock divider, which should've been 1:1. This introduces
quirk which conditionally re-configures the clock divider to 1:1.
