7 title: ARM Timer-Watchdog Timer
10 - Rob Herring <robh@kernel.org>
13 ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
14 Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
17 The TWD is usually attached to a GIC to deliver its two per-processor

25 - arm,arm11mp-twd-timer
38 If present, the timer is powered through an always-on power domain,
39 therefore it never loses context.
