Qualcomm Technologies, Inc. CX Peak current cooling device
|
|
|
|
The CX IPEAK cooling device, will be used to set thermal client vote to
|
|
CX IPEAK LM hardware. When all pre-defined clients on CX rail including
|
|
thermal client set their vote, CXIP LM hardware throttles pre-defined
|
|
client on the same rail.
|
|
|
|
Required Parameters:
|
|
- compatible:
|
|
Usage: required
|
|
Value type: <string>
|
|
Definition: should be "qcom,cxip-lm-cooling-device"
|
|
|
|
- reg:
|
|
Usage: required
|
|
Value type: <values in hex>
|
|
Definition: Must contain 2 variables <a b> where 'a' is the starting
|
|
register address of the CX IPEAK LM hardware and 'b' is the
|
|
size of the peripheral address space.
|
|
|
|
- qcom,thermal-client-offset:
|
|
Usage: Optional
|
|
Value type: <value in hex>
|
|
Definition: This property is required for CX IP LM v1.1 and above
|
|
hardware. Must contain offset from CX IPEAK LM reg
|
|
base for thermal client voting. If this property is not defined,
|
|
then CX IPEAK cooling device will use legacy CXIP LM hardware
|
|
offset registers.
|
|
|
|
- qcom,bypass-client-list:
|
|
Usage: Optional
|
|
Value type: <value in hex>
|
|
Definition: This property is required for CX IP LM v1.1 and above
|
|
hardware. Must contain array of offsets from CX IPEAK LM reg
|
|
base for clients those are not participating voting to CXIP LM
|
|
hardware. This property makes sense only when thermal-client
|
|
is defined.
|
|
|
|
- #cooling-cells:
|
|
Usage: required
|
|
Value type: <integer>
|
|
Definition: Must be 2. This is required by of-thermal and refer the doc
|
|
<devicetree/bindings/thermal/thermal.txt> for more details.
|
|
|
|
Example:
|
|
|
|
cxip_cdev: cxip-cdev@1fed000 {
|
|
compatible = "qcom,cxip-lm-cooling-device";
|
|
reg = <0x1fed000 0x24>;
|
|
qcom,thermal-client-offset = <0x8000>;
|
|
qcom,bypass-client-list = <0x2004 0x3004>;
|
|
#cooling-cells = <2>;
|
|
};
