1* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs 2 3Required properties: 4- compatible : Must include "fsl,qoriq-tmu" or "fsl,imx8mq-tmu". The 5 version of the device is determined by the TMU IP Block Revision 6 Register (IPBRR0) at offset 0x0BF8. 7 Table of correspondences between IPBRR0 values and example chips: 8 Value Device 9 ---------- ----- 10 0x01900102 T1040 11- reg : Address range of TMU registers. 12- interrupts : Contains the interrupt for TMU. 13- fsl,tmu-range : The values to be programmed into TTRnCR, as specified by 14 the SoC reference manual. The first cell is TTR0CR, the second is 15 TTR1CR, etc. 16- fsl,tmu-calibration : A list of cell pairs containing temperature 17 calibration data, as specified by the SoC reference manual. 18 The first cell of each pair is the value to be written to TTCFGR, 19 and the second is the value to be written to TSCFGR. 20- #thermal-sensor-cells : Must be 1. The sensor specifier is the monitoring 21 site ID, and represents the "n" in TRITSRn and TRATSRn. 22 23Optional property: 24- little-endian : If present, the TMU registers are little endian. If absent, 25 the default is big endian. 26- clocks : the clock for clocking the TMU silicon. 27 28Example: 29 30tmu@f0000 { 31 compatible = "fsl,qoriq-tmu"; 32 reg = <0xf0000 0x1000>; 33 interrupts = <18 2 0 0>; 34 fsl,tmu-range = <0x000a0000 0x00090026 0x0008004a 0x0001006a>; 35 fsl,tmu-calibration = <0x00000000 0x00000025 36 0x00000001 0x00000028 37 0x00000002 0x0000002d 38 0x00000003 0x00000031 39 0x00000004 0x00000036 40 0x00000005 0x0000003a 41 0x00000006 0x00000040 42 0x00000007 0x00000044 43 0x00000008 0x0000004a 44 0x00000009 0x0000004f 45 0x0000000a 0x00000054 46 47 0x00010000 0x0000000d 48 0x00010001 0x00000013 49 0x00010002 0x00000019 50 0x00010003 0x0000001f 51 0x00010004 0x00000025 52 0x00010005 0x0000002d 53 0x00010006 0x00000033 54 0x00010007 0x00000043 55 0x00010008 0x0000004b 56 0x00010009 0x00000053 57 58 0x00020000 0x00000010 59 0x00020001 0x00000017 60 0x00020002 0x0000001f 61 0x00020003 0x00000029 62 0x00020004 0x00000031 63 0x00020005 0x0000003c 64 0x00020006 0x00000042 65 0x00020007 0x0000004d 66 0x00020008 0x00000056 67 68 0x00030000 0x00000012 69 0x00030001 0x0000001d>; 70 #thermal-sensor-cells = <1>; 71}; 72
