* Broadcom STB thermal management
|
||||
|
||||
Thermal management core, provided by the AVS TMON hardware block.
|
||||
|
||||
Required properties:
|
||||
- compatible: must be "brcm,avs-tmon" and/or "brcm,avs-tmon-bcm7445"
|
||||
- reg: address range for the AVS TMON registers
|
||||
- interrupts: temperature monitor interrupt, for high/low threshold triggers
|
||||
- interrupt-names: should be "tmon"
|
||||
- interrupt-parent: the parent interrupt controller
|
||||
|
||||
Example:
|
||||
|
||||
thermal@f04d1500 {
|
||||
compatible = "brcm,avs-tmon-bcm7445", "brcm,avs-tmon";
|
||||
reg = <0xf04d1500 0x28>;
|
||||
interrupts = <0x6>;
|
||||
interrupt-names = "tmon";
|
||||
interrupt-parent = <&avs_host_l2_intc>;
|
||||
};
|
||||
@ -7,10 +7,17 @@ Required properties:
|
||||
is higher than panic threshold, system will auto reboot by SRC module.
|
||||
- fsl,tempmon : phandle pointer to system controller that contains TEMPMON
|
||||
control registers, e.g. ANATOP on imx6q.
|
||||
- nvmem-cells: A phandle to the calibration cells provided by ocotp.
|
||||
- nvmem-cell-names: Should be "calib", "temp_grade".
|
||||
|
||||
Deprecated properties:
|
||||
- fsl,tempmon-data : phandle pointer to fuse controller that contains TEMPMON
|
||||
calibration data, e.g. OCOTP on imx6q. The details about calibration data
|
||||
can be found in SoC Reference Manual.
|
||||
|
||||
Direct access to OCOTP via fsl,tempmon-data is incorrect on some newer chips
|
||||
because it does not handle OCOTP clock requirements.
|
||||
|
||||
Optional properties:
|
||||
- clocks : thermal sensor's clock source.
