1* Broadcom Stingray Thermal 2 3This binding describes thermal sensors that is part of Stingray SoCs. 4 5Required properties: 6- compatible : Must be "brcm,sr-thermal" 7- reg : Memory where tmon data will be available. 8- brcm,tmon-mask: A one cell bit mask of valid TMON sources. 9 Each bit represents single TMON source. 10- #thermal-sensor-cells : Thermal sensor phandler 11- polling-delay: Max number of milliseconds to wait between polls. 12- thermal-sensors: A list of thermal sensor phandles and specifier. 13 specifier value is tmon ID and it should be 14 in correspond with brcm,tmon-mask. 15- temperature: trip temperature threshold in millicelsius. 16 17Example: 18 tmons { 19 compatible = "simple-bus"; 20 #address-cells = <1>; 21 #size-cells = <1>; 22 ranges = <0x0 0x0 0x8f100000 0x100>; 23 24 tmon: tmon@0 { 25 compatible = "brcm,sr-thermal"; 26 reg = <0x0 0x40>; 27 brcm,tmon-mask = <0x3f>; 28 #thermal-sensor-cells = <1>; 29 }; 30 }; 31 32 thermal-zones { 33 ihost0_thermal: ihost0-thermal { 34 polling-delay-passive = <0>; 35 polling-delay = <1000>; 36 thermal-sensors = <&tmon 0>; 37 trips { 38 cpu-crit { 39 temperature = <105000>; 40 hysteresis = <0>; 41 type = "critical"; 42 }; 43 }; 44 }; 45 ihost1_thermal: ihost1-thermal { 46 polling-delay-passive = <0>; 47 polling-delay = <1000>; 48 thermal-sensors = <&tmon 1>; 49 trips { 50 cpu-crit { 51 temperature = <105000>; 52 hysteresis = <0>; 53 type = "critical"; 54 }; 55 }; 56 }; 57 ihost2_thermal: ihost2-thermal { 58 polling-delay-passive = <0>; 59 polling-delay = <1000>; 60 thermal-sensors = <&tmon 2>; 61 trips { 62 cpu-crit { 63 temperature = <105000>; 64 hysteresis = <0>; 65 type = "critical"; 66 }; 67 }; 68 }; 69 ihost3_thermal: ihost3-thermal { 70 polling-delay-passive = <0>; 71 polling-delay = <1000>; 72 thermal-sensors = <&tmon 3>; 73 trips { 74 cpu-crit { 75 temperature = <105000>; 76 hysteresis = <0>; 77 type = "critical"; 78 }; 79 }; 80 }; 81 crmu_thermal: crmu-thermal { 82 polling-delay-passive = <0>; 83 polling-delay = <1000>; 84 thermal-sensors = <&tmon 4>; 85 trips { 86 cpu-crit { 87 temperature = <105000>; 88 hysteresis = <0>; 89 type = "critical"; 90 }; 91 }; 92 }; 93 nitro_thermal: nitro-thermal { 94 polling-delay-passive = <0>; 95 polling-delay = <1000>; 96 thermal-sensors = <&tmon 5>; 97 trips { 98 cpu-crit { 99 temperature = <105000>; 100 hysteresis = <0>; 101 type = "critical"; 102 }; 103 }; 104 }; 105 };
