[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.
