[Johan Jonker]

Hi,

Sorry.
This can go in the bin...
It needs more cleanup...
See question below.

The trip property points to "cpu_alert1", while in rk3399.dtsi that is
"&cpu_alert0"
What is correct here?

				map0 {
					trip = <&cpu_alert0>;
					cooling-device =
						<&cpu_b0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>,
						<&cpu_b1 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
				};
