Subject: [PATCH-V2 0/3] ARM: OMAP: Make OMAP clocksource source selection runtime
Date: Fri, 30 Mar 2012 19:24:12 +0530 [thread overview]
Message-ID: <1333115655-28530-1-git-send-email-hvaibhav@ti.com> (raw)
Current OMAP code supports couple of clocksource options based
on compilation flag (CONFIG_OMAP_32K_TIMER). The 32KHz sync-timer
and a gptimer which can run on 32KHz or system clock (e.g 38.4 MHz)
This patch series cleans up the existing 32k-sync timer implementation
without any major code change, in order to enable runtime selection between
32k sync-timer and gptimer 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 OMAP1/2
platforms.
Changes from previous submissions:
==================================
Changes from V1:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-January/081037.html
- Based on Tony's comment, added pbase & size argument to
omap_init_clocksource_32k(), to avoid cpu_is_xxx() check.
- Added commit description based on discussion on list
(Thanks to Santosh here)
- Reorder patch sequence
