    ARM: dts: motorola-mapphone: Configure lower temperature passive cooling · 5c3db2d4
    Tony Lindgren authored
    The current cooling device temperature is too high at 100C as we have a
    battery on the device right next to the SoC as pointed out by Carl Philipp
    Klemm <philipp@uvos.xyz>. Let's configure the max temperature to 80C.
    
    As we only have a tshut interrupt and no talert interrupt on 4430, we have
    a passive cooling device configured for 4430. However, we want the poll
    interval to be 10 seconds instead of 1 second for power management. The
    value of 10 seconds seems like plenty of time to notice the temperature
    increase above the 75C temperatures. Having the bandgap temperature change
    seems to take several tens of seconds because of heat dissipation above
    75C range as monitored with a full CPU load.
