If anyone has any objections, please let me know. ------------------ From: Tony Lindgren [ Upstream commit 5c3db2d4d4ed747e714387362afe007e6ae5e2d3 ] 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 . 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.
