Hi,
This patches support pmu irq routed from CTI, such as implemented
on OMAP4:
- introduce some CTI helpers and registers' definition
- introduce .enable_irq and .disable_irq into platform_data,
so perf irq handler can handle irq correctly if it is routed
from CTI on OMAP4
- configure CTI on OMAP4 so that perf can work on OMAP4
The patches have been tested Ok on Pandaboard, and 'perf' does work
after applying them.
v5:
- build pmu device from hwmod
- support runtime pm
v4:
- some minor fix(add __iomem, comments, checkpatch warning...)
v3:
- fix typo of patch 2/3 title, pointed by Will
- move cti addresses to plat/omap44xx.h, suggested by
Santosh Shilimkar
v2:
- move cti related code out of perf_event.c
- introduce .enable_irq and .disable_irq into platform_data
as suggested by Will.
v1:
- rebase the patch set against 2.6.38-rc6-next-20110301, fix
conflicts, which is pointed out by Will Deacon
