commit 0d8e2d0dad (OMAP2+: PM/serial:
hold console semaphore while OMAP UARTs are disabled) added use of the
console semaphore to protect UARTs from being accessed after disabled
during idle, but this causes problems in suspend.
During suspend, the console semaphore is acquired by the console
suspend method (console_suspend()) so the try_acquire_console_sem()
will always fail and suspend will be aborted.
To fix, introduce a check so the console semaphore is only attempted
during idle, and not during suspend. Also use the same check so that
the console semaphore is not prematurely released during resume.
Thanks to Paul Walmsley for suggesting adding the same check during
resume.

Implement GPIO as a platform device.
GPIO APIs are used in machine_init functions. Hence it is
required to complete GPIO probe before board_init. Therefore
GPIO device register and driver register are implemented as
postcore_initcalls.
omap_gpio_init() does nothing now and this function would be
removed in the next patch as it's usage is spread across most
of the board files.
Inorder to convert GPIO as platform device, modifications are
required in clockxxxx_data.c file for OMAP1 so that device names
can be used to obtain clock instead of getting clocks by
name/NULL ptr.
Use runtime pm APIs (pm_runtime_put*/pm_runtime_get*) for enabling
or disabling the clocks, modify sysconfig settings and remove usage
of clock FW APIs.
Note 1: Converting GPIO driver to use runtime PM APIs is not done as a
separate patch because GPIO clock names are different for various OMAPs
and are different for some of the banks in the same CPU. This would need
usage of cpu_is checks and bank id checks while using clock FW APIs in
the gpio driver. Hence while making GPIO a platform driver framework,
PM runtime APIs are used directly.
Note 2: While implementing GPIO as a platform device, pm runtime APIs
are used as mentioned above and modification is not done in gpio's
prepare for idle/ resume after idle functions. This would be done
in the next patch series and GPIO driver would be made to use dev_pm_ops
instead of sysdev_class in that series only.
Due to the above, the GPIO driver implicitly relies on
CM_AUTOIDLE = 1 on its iclk for power management to work, since the
driver never disables its iclk.
This would be taken care in the next patch series (see Note 3 below).
Refer to
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg39112.html
for more details.
Note 3: only pm_runtime_get_sync is called in gpio's probe() and
pm_runtime_put* is never called. This is to make the implementation
similar to the existing GPIO code. Another patch series would be sent
to correct this.
In OMAP3 and OMAP4 gpio's debounce clocks are optional clocks. They
are enabled/ disabled whenever required using clock framework APIs
TODO:
1. Cleanup the GPIO driver. Use function pointers and register
offest pointers instead of using hardcoded values
2. Remove all cpu_is_ checks and OMAP specific macros
3. Remove usage of gpio_bank array so that only
instance specific information is used in driver code
4. Rename 'method'/ avoid it's usage
5. Fix the non-wakeup gpios handling for OMAP2430, OMAP3 & OMAP4
6. Modify gpio's prepare for idle/ resume after idle functions
to use runtime pm implentation.
