dtc complains about the extclock-gpio property because it expects a
property named *-gpio to contain a gpio-list:

    DTC     arch/mips/boot/dts/img/pistachio_marduk.dtb
  arch/mips/boot/dts/img/pistachio_marduk.dtb: Warning (gpios_property):
    /spi@18100f00/sixlowpan@4: Missing property '#gpio-cells' in node
    /clk@18144000 or bad phandle (referred from extclock-gpio[0])

Rob, perhaps this should be added as a second false-positive case in
dtc's prop_is_gpio()?

Thanks,
