[PATCH 0/3] ARM: rockchip: provide the watchdog with a clock

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.

  clk: rockchip: add a dummy clock for the watchdog pclk on rk3288
  ARM: dts: rockchip: add rk3288 watchdog clock
