[PATCH 1/5] ARM: rockchip: move shared dt properties to common source file

[Heiko Stübner]

The rk3188 SoC shares a lot of peripherals with the rk3066 SoC,
but not all. Therefore move the common parts to a shared dtsi.

[PATCH 2/5] ARM: rockchip: enable arm-global-timer

[Heiko Stübner]

RK2928 and RK3066 contain a dw_apb timer component, while the rk3188 uses
a slightly similar but still different timer component. But all of them
support the ARM-global-timer that got added as clocksource driver recently.

So enable support for it to get a working clocksource for rk3188.

[PATCH 5/5] MAINTAINERS: Add maintainers entry for Rockchip SoCs

[Heiko Stübner]

I plan to stay with the Rockchip SoCs for the foreseable future
and hope to expand its support along the way.
