Minor cleanup without functional impact: 1. Indent DTS examples to preferred four-spaces (more readable for DTS), 2. Drop unneeded quotes, 3. Add/drop blank lines to make the code readable.

|
|
ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
|
|
Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
|
|
and watchdog.
|
|
|
|
The TWD is usually attached to a GIC to deliver its two per-processor
|
|
interrupts.
