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. http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg37403.html Yesterday I had submitted the RFC version patch-series, which was built on top of earlier cleanup patches from 'Fillipe Balbi'. http://www.spinics.net/lists/linux-omap/msg63004.html Based on comments (Thanks to Russell, Marc and Tony) from community it was clear that, arch_init is not the correct way here.
