I'm thinking:
timer@200a000 {
compatible = "qcom,kpss-timer", "qcom,msm-timer";
interrupts = <1 1 0x301>,
<1 2 0x301>,
<1 3 0x301>,
<1 4 0x301>,
<1 5 0x301>;
reg = <0x0200a000 0x100>;
clock-frequency = <27000000>,
<32768>;
clocks = <&cxo>, <&sleep_clk>;
clock-names = "ref", "sleep";
cpu-offset = <0x80000>;
};
Where'd the default timeout configuration go? Or, should we have one
timeout-sec property and not allow setting the default timeouts per WDT
instance? Or no configurable timeout at all?
Ah sorry. How about a timeout-sec-0, timeout-sec-1 property that is
per-cpu and maps to the first and second watchdog timer? Something like:
timeout-sec-wdt0 = <10 8>;
timeout-sec-wdt1 = <20 15>;
