ARM: 6125/1: ARM TWD: move TWD registers to common header This moves the TWD register set of MPcore to a common existing file so that watchdog driver can access it Signed-off-by: srinidhi kasagar <srinidhi.kasagar@stericsson.com> Acked-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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