| * Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs |
| |
| Required properties: |
| - compatible : Must include "fsl,qoriq-tmu" or "fsl,imx8mq-tmu". The |
| version of the device is determined by the TMU IP Block Revision |
| Register (IPBRR0) at offset 0x0BF8. |
| Table of correspondences between IPBRR0 values and example chips: |
| Value Device |
| ---------- ----- |
| 0x01900102 T1040 |
| - reg : Address range of TMU registers. |
| - interrupts : Contains the interrupt for TMU. |
| - fsl,tmu-range : The values to be programmed into TTRnCR, as specified by |
| the SoC reference manual. The first cell is TTR0CR, the second is |
| TTR1CR, etc. |
| - fsl,tmu-calibration : A list of cell pairs containing temperature |
| calibration data, as specified by the SoC reference manual. |
| The first cell of each pair is the value to be written to TTCFGR, |
| and the second is the value to be written to TSCFGR. |
| - #thermal-sensor-cells : Must be 1. The sensor specifier is the monitoring |
| site ID, and represents the "n" in TRITSRn and TRATSRn. |
| |
| Optional property: |
| - little-endian : If present, the TMU registers are little endian. If absent, |
| the default is big endian. |
