Subject: [PATCH 0/2] clocksource: add rockchip rk3288 specific armv7-timer

The architected timer on Rockchip's RK3288 SoCs needs a bit of special handling
to start.

This seems to be similar to a recent discussion about the Exynos arch-timer
that also seems to need similar special handling (and mct timer running).

And, the arch-timer on recent Mediatek SoCs also uses this pattern of a
supplying timer below the arch-timer.

Therefore follow a suggestion from Arnd Bergmann and implement a separate
clocksource for it that does the setup and then initializes the arch-timer.

This series uses "of: Provide function to request and map memory" from
Matthias Brugger.

  clocksource: arm_arch_timer: remove static from arch_timer_init
  clocksource: add rockchip-specific armv7-timer setup
