The emulated thermal sensor can report temperatures in increments 20 of 0.125 degrees, ranging from 0 to 255.875. 21 22properties: 23 compatible: 24 enum: 25 - amd,sbtsi 26 27 reg: 28 maxItems: 1 29 description: | 30 I2C bus address of the device as specified in Section 6.3.1 of the 31 SoC register reference.
