There are four CPU clock post dividers: - ABP - PERIPH (used for the ARM global timer and ARM TWD timer) - AXI - L2 DRAM Each of these clocks consists of two clocks: - a mux to select between "cpu_clk" divided by 2, 3, 4, 5, 6, 7 or 8 - a "_clk_dis" gate. The public S805 datasheet states that this should be set to 1 to disable the clock, the default value is 0. There is also a hint that these are "just in case" bits which only exist in case the corresponding mux implementation does not allow glitch-free parent changes (the muxes are designed in a way that the clock can stay enabled when changing the mux). It's still good practise to describe this clock even if we're not supposed to modify it. Thus this uses the read-only gate ops.
