[PATCH v3 00/13] gpio/omap: Some more driver cleanup and fixes

[Tarun Kanti DebBarma]

The cleanup is mostly getting rid of redundant fields in struct gpio_bank{}
as we already have them as part of bank->context now. Also, remove un-used
variable from gpio_irq_handler.

The fixes include correction of _set_gpio_irqenable() implementation,
missing wakeup_en register update in set_gpio_wakeup(), type mismatch
of gpio trigger parameter in set_gpio_trigger(), incorrect dataout
register update in set_gpio_dataout_() and few corrections in context
save logic.

It is baselined on top of Kevin's following series:
gpio/omap: cleanup and runtime PM conversion for v3.4
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git for_3.4/gpio/runtime-pm-cleanup

Series is available here for reference:
git://gitorious.org/~tarunkanti/omap-sw-develoment/tarunkantis-linux-omap-dev for_3.4/gpio_further_cleanup_fixes

Power Test: Off-mode and Retention on OMAP3430 (Suspend and Idle paths).
Functional Test: OMAP2430, OMAP3430SDP, ZOOM3, OMAP4430, OMAP4-BLAZE

v3:
- Added 4 more additional patches to the previous series
  which are all bug fixes.

v2:
- Added a new patch to update wakeup_en register in _set_gpio_wakeup()
 in addition to updating bank->context.wake_en.

- Added a new patch to remove redundant decoding of gpio offset in
 gpio_get(), _get_gpio_datain() and _get_gpio_dataout().

- Added a new patch to remove suspend/resume callbacks because the
 operations performed with the callbacks are redundant.
