ARM: gic, local timers: use the request_percpu_irq() interface

2011-10-23T12:32:33Z

This patch remove the hardcoded link between local timers and PPIs, and convert the PPI users (TWD, MCT and MSM timers) to the new *_percpu_irq interface. Also some collateral cleanup (local_timer_ack() is gone, and the interrupt handler is strictly private to each driver). PPIs are now useable for more than just the local timers. Additional testing by David Brown (msm8250 and msm8660) and Shawn Guo (imx6q).

msm: timer: compensate for timer shift in msm_read_timer_count

2011-06-17T21:54:18Z

Some msm targets have timers whose lower bits are unreliable. So, we present our timers as lower frequency than they actually are, and ignore the bottom 5 bits on such targets. This compensation was erroneously removed from the msm_read_timer_count function, so restore it. This was broken by 94790ec25 "msm: timer: SMP timer support for msm". Signed-off-by: Jeff Ohlstein

msm: timer: fix missing return value

2011-03-31T20:15:40Z

Change af90f10d38 "ARM: 6759/1: smp: Select local timers vs broadcast timer support runtime" missed a return statement, causing a compile warning: arch/arm/mach-msm/timer.c:272: warning: 'return' with no value, in function returning non-void Trivially return 0 for success when running on cpu 0 (to match the comment and previous behavior).

ARM: 6759/1: smp: Select local timers vs broadcast timer support runtime

2011-02-23T17:54:27Z

The current code support of dummy timers in absence of local timer is compile time. This is an attempt to convert it to runtime so that on few SOC version if the local timers aren't supported kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from this limitation. This patch should not have any functional impact on affected files.

msm: Generalize timer register mappings

msm: timer: SMP timer support for msm

2011-01-07T23:54:44Z

The msm provides timer hardware that is private to each core. Each timer has separate counter and match registers, so we create separate clock_event_devices for each core. For the global clocksource, use cpu 0's counter. Signed-off-by: Jeff Ohlstein Signed-off-by: David Brown
