Populate the PM domains from DT, and provide support to hook up devices to their respective PM domain. The always-on power area (e.g. C5 on r8a7740) is created as a PM domain without software control, to allow Run-Time management of module clocks for hardware blocks inside this area. Special cases like PM domains containing CPUs, the console device, or Coresight-ETM, are handled by scanning the DT topology. As long as the ARM debug/perf code doesn't use resource management with runtime PM support, the power area containing Coresight-ETM (e.g. D4 on r8a7740) must be kept powered to avoid a crash during resume from s2ram (dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an undefined instruction oops). Initialization is done from core_initcall(), as the "renesas,intc-irqpin" driver uses postcore_initcall().

Allows the configuration of the timer frequency. It is customary
|
|
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
|
|
case of low timer frequencies other values may be more suitable.
|
|
Renesas ARM SoC systems using a 32768 Hz RCLK for clock events may
|
|
want to select a HZ value such as 128 that can evenly divide RCLK.
|
|
A HZ value that does not divide evenly may cause timer drift.
