2013-03-11ARM: smp_twd: convert to use CLKSRC_OF initRob Herring1-8/+0
Now that we have OF based init with CLKSRC_OF, convert smp_twd init function to use it and covert all callers of twd_local_timer_of_register.

2012-03-13ARM: smp_twd: remove old local timer interfaceMarc Zyngier1-6/+0
Now that all users of the previous local timer interface have been converted to the runtime registration API, make this interface the only one supported for this driver. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13ARM: smp_twd: add device tree supportMarc Zyngier1-0/+8
Add bindings to support DT discovery of the ARM Timer Watchdog (aka TWD). Only the timer side is converted by this patch. Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13ARM: smp_twd: add runtime registration supportMarc Zyngier1-1/+17
Add support for the new registration interface to smp_twd. Platforms can populate a struct twd_local_timer with MMIO and IRQ resources, and then call twd_local_timer_register() to have the timer registered with the core. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13ARM: smp_twd: make local_timer_stop a symbol instead of a #defineMarc Zyngier1-1/+0
When CONFIG_HAVE_ARM_TWD is selected, local_timer_stop is a #define, while all other local timers are using a real function. Convert it to an alias of twd_timer_stop, as it helps converting all local timers to another internal API in a sane way. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2011-10-23ARM: gic, local timers: use the request_percpu_irq() interfaceMarc Zyngier1-1/+1
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).

2010-12-20ARM: localtimer: clean up local timer on hot unplugRussell King1-1/+0
When a CPU is hot unplugged, the generic tick code cleans up the clock event device, but fails to call down to the device's set_mode function to actually shut the device down. To work around this, we've historically had a local_timer_stop() callback out of the hotplug code. However, this adds needless complexity when we have the clock event device itself available. Explicitly call the clock event device's set_mode function with CLOCK_EVT_MODE_UNUSED, so that the hardware can be cleanly shutdown without any special external callbacks. When/if the generic code is fixed, percpu_timer_stop() can be killed off. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
