ARM: rockchip: provide the watchdog with a clock

A patchset in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Wed, 21 Jan 2015 20:48:18 +0100

The snps,dw-wdt needs to read the clock-rate of its supplying clock for some operations. The clock itself is based on pclk_pd_alive and is indeed gateable. The caveat is that the gate is living in the so-called secure-GRF, which isn't even writeable in some boot-modes. But to have an actual clock reference to the correct clock, implement a fixed-factor clock, to be substituted when we can control the actual gate safely.
