* 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.
- clocks : the clock for clocking the TMU silicon.
Example:
tmu@f0000 {
compatible = "fsl,qoriq-tmu";
reg = <0xf0000 0x1000>;
interrupts = <18 2 0 0>;
