Jingoo Han 37e4901449 pinctrl: plgpio: add CONFIG_PM_SLEEP to suspend/resume functions
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

Catalin Marinas de88cbb7b2 arm: Move chained_irq_(enter|exit) to a generic file
These functions have been introduced by commit 10a8c383 (irq: introduce
entry and exit functions for chained handlers) in asm/mach/irq.h. This
patch moves them to linux/irqchip/chained_irq.h so that generic irqchip
drivers do not rely on architecture specific header files.

Thierry Reding 9e0c1fb29a pinctrl: Convert to devm_ioremap_resource()
Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

Greg Kroah-Hartman 150632b09a Drivers: pinctrl: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Viresh Kumar f92bc45ffd Pinctrl/spear: plgpio: don't call prepare/unprepare
SPEAr SoC's don't do anything in clk_prepare() of plgpio driver,
so there is no need to call this routine multiple times. Just
call it once at probe.

Axel Lin 9804049097 pinctrl: plgpio: Call clk_disable_unprepare only if clk_prepare_enable is called
This driver allows clk_get() failure, and still work without it.
This patch adds !IS_ERR(plgpio->clk) checking in plgpio_request() error path
so we only call clk_disable_unprepare() if clk_prepare_enable() is called.

these pads as gpio.
