The CPRMAN (clock controller) was mapped at the watchdog/power manager
address. It was also split into two unimplemented peripherals (CM and
A2W) but this is really the same one, as shown by this extract of the
Raspberry Pi 3 Linux device tree:

    watchdog@7e100000 {
            compatible = "brcm,bcm2835-pm\0brcm,bcm2835-pm-wdt";
            [...]
            reg = <0x7e100000 0x114 0x7e00a000 0x24>;
            [...]
    };

    [...]
    cprman@7e101000 {
            compatible = "brcm,bcm2835-cprman";
            [...]
            reg = <0x7e101000 0x2000>;
            [...]
    };
