Stephen Boyd 70a26071f8 Input: pmic8xxx-pwrkey - set sane default for debounce time
If the debounce time is 0 our usage of ilog2() later on in this driver will
cause undefined behavior. If CONFIG_OF=n this fact is evident to the
compiler, and it emits a call to ____ilog2_NaN() which doesn't exist. Fix
this by setting a sane default for debounce and failing to probe if
debounce is 0 in the DT.

Stephen Boyd 57918dfadf Input: pmic8xxx-pwrkey - migrate to DT
The driver is only supported on DT enabled platforms. Convert the
driver to DT so that it can probe properly.

Paul Gortmaker bf9a9f8e51 Input: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Wei Yongjun e77a715ac3 Input: pmic8xxx-pwrkey - pass correct device identity to free_irq()
free_irq() in the error handling case is missing when change
pass input device directly to interrupt.

Stephen Boyd 1e63bd9cc4 Input: pmic8xxx-pwrkey - migrate to regmap APIs
Use the regmap APIs for this driver instead of custom pm8xxx
APIs. This breaks this driver's dependency on the pm8xxx APIs and
allows us to easily port it to other bus protocols in the future.

Stephen Boyd b27f8fee49 Input: pmic8xxx-pwrkey - pass input device directly to interrupt
Instead of passing the pointer to the container structure just
pass the input device here. This saves a dereference in the fast
path.

Lars-Peter Clausen 139097a0a7 Input: pmic8xxx-pwrkey - pass correct pointer to free_irq()
free_irq() expects the same pointer that was passed to request_irq(),
otherwise the IRQ is not freed.
