| * Broadcom Stingray Thermal |
| |
| This binding describes thermal sensors that is part of Stingray SoCs. |
| |
| Required properties: |
| - compatible : Must be "brcm,sr-thermal" |
| - reg : Memory where tmon data will be available. |
| - brcm,tmon-mask: A one cell bit mask of valid TMON sources. |
| Each bit represents single TMON source. |
| - #thermal-sensor-cells : Thermal sensor phandler |
| - polling-delay: Max number of milliseconds to wait between polls. |
| - thermal-sensors: A list of thermal sensor phandles and specifier. |
| specifier value is tmon ID and it should be |
| in correspond with brcm,tmon-mask. |
| - temperature: trip temperature threshold in millicelsius. |
| |
| Example: |
| tmons { |
| compatible = "simple-bus"; |
| #address-cells = <1>; |
| #size-cells = <1>; |
| ranges = <0x0 0x0 0x8f100000 0x100>; |
| |
| tmon: tmon@0 { |
| compatible = "brcm,sr-thermal"; |
| reg = <0x0 0x40>; |
| brcm,tmon-mask = <0x3f>; |
| #thermal-sensor-cells = <1>; |
| }; |
