[PATCH v4 RESEND 0/7] gpio/omap: Some more driver fixes

[Tarun Kanti DebBarma]

This series excludes the cleanup patches as suggested by Kevin from
the previously posted series.

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.

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

Power Test:
Off-mode and Retention on OMAP3430 (Suspend and Idle paths).
Also confirmed that dataout register content preserved over
off-mode.

Functional Test:
OMAP2430, OMAP3430SDP, ZOOM3, OMAP4430, OMAP4-BLAZE

v4:
a) Implemented all comments on v3 which are mostly related to
avoiding unnecessary register read while updating the context.

b) Folded:
gpio/omap: fix dataout register overwrite in _set_gpio_dataout
into:
gpio/omap: fix missing dataout context save in _set_gpio_dataout_reg

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.
