[PATCH 0/3] ARM: OMAP1/2+: 32k-timer: Add hwmod lookup for 32k-timer

[hvaibhav@ti.com (Vaibhav Hiremath)]

This patch series cleans up the existing 32k-sync timer implementation
without any major code change and adds hwmod lookup for omap2+ devices,
if lookup fails then fall back to gp-timer.

With this, we should be able to support multi-omap boot
including devices with/without 32k-sync timer.
For example, AM33xx device doesn't have 32k-sync timer available,
which breaks multi-omap boot.

This patch-series has been boot tested on AM37xEVM platform, it
would be helpful if somebody help me to validate it on OMAP2
platform.

Background:
==========
In 2010 timeframe 'Fillipe Balbi' had submitted first version
of 32k-sync timer cleanup patches, but it did not made its way
to the mainline.

Yesterday I had submitted the RFC version patch-series, which was
built on top of earlier cleanup patches from 'Fillipe Balbi'.

Based on comments (Thanks to Russell, Marc and Tony) from community
it was clear that, arch_init is not the correct way here.

  ARM: OMAP2+: 32k-counter: Use hwmod lookup to check presence of 32k
    timer
  ARM: OMAP2/3: Add idle_st bits for ST_32KSYNC timer to prcm-common
    header
  ARM: OMAP2+: hwmod data: Add 32k-sync timer data to hwmod database
