[RFC PATCH 0/5] arm:omap1/2/3/4: 32k sync timer cleanup

[Vaibhav Hiremath <hvaibhav@xxxxxx>]

This patch series is built on top of older version submitted
earlier during 2010 timeframe by 'Felipe Balbi' -

http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg37403.html

Changes from earlier submitted version:
	- hwmod cleanup: Since 2010 there has been some changes happened
	  in hwmod interface, migrated to the latest version.
	- wrong hwmod info: the previous version had some issues with newly
	  added 32k-counter hwmod data, like, base_addr,
	  idle_st bit position. So corrected these errors.
	- In omap-32k platform driver, replaced
	  clocksource_register => clocksource_register_hz
	- Merged patches into more logical grouping

NOTE: Patch series has been tested on AM37xEVM, AM3517EVM, AM335xEVM,
      with/without kernel parameter "clocksource=".

The reason why I am submitting this patch-series as a RFC version is,

I am struggling to convince myself and find answers for -

	- Do we really required platform_driver approach here?
	- Can we simply cleaup the existing plat-omap/counter_32k.c
	  file and add hwmod lookup to make decesion whether the
	  module is present or not on the current device?
	- what about existing mmio driver/api? we can avoid some
	  code duplication here.

So I decided to start with RFC with the existing (already submitted)
approach and get the expert peoples view on this.
Based on feedback I will submit next version.
