* lantiq: fix thermal sensors driverMathias Kresin2016-10-191-5/+21
| | | | | | | | | | | | | | | | | | | | Read the temperature including the decimale place from the CGU_GPHY1_CR register. Decrement the temperature read from the register by 38.0 degree celsius. The temperature range of the sensor is -38.0 to +154 °C and the register value 0 is equal to -38.0 °C. This fixes the report of unrealistic temperatures as seen on all tested boards. Give the SoC a few milliseconds to get the first temperature value. On some rare occasions there is no temperature value in the register when read the first time after activation. This leads to a reported temperature of -38.0 °C on boot. Only version 1.2 of the vr9 SoC has a temperature sensor. Add a check to make sure the driver doesn't load on v1.1 vr9 SoCs.
