* MSM MPM sleep counter (mpm-v2)
|
|
|
|
The MPM provides a timetick that starts when the device is powered up and
|
|
is not reset by any of the boot loaders or the HLOS. The MPM timetick counter
|
|
driver provides an api to get this value.
|
|
|
|
The required nodes for the MPM timetick counter driver are:
|
|
|
|
- compatible: "qcom,mpm2-sleep-counter"
|
|
- reg: Specifies the physical address of the timetick count register.
|
|
- clock-frequency: the physical counter frequency.
|
|
|
|
Example:
|
|
qcom,mpm2-sleep-counter@fc4a3000 {
|
|
compatible = "qcom,mpm2-sleep-counter";
|
|
reg = <0xfc4a3000 0x1000>;
|
|
clock-frequency = <32768>;
|
|
};
|
