Add qcom epm hardware device driver. It enables to measure different pmic regulator power consumption data and pmic temperature data. It exposes these data to userspace clients via powercap sysfs interface and thermal zone sysfs interface respectively.

The power capping sysfs interface allows kernel subsystems to expose power
|
|
capping settings to user space in a consistent way. Usually, it consists
|
|
of multiple control types that determine which settings may be exposed and
|
|
power zones representing parts of the system that can be subject to power
|
|
capping.

This enables support for the Intel Running Average Power Limit (RAPL)
|
|
technology via MSR interface, which allows power limits to be enforced
|
|
and monitored on modern Intel processors (Sandy Bridge and later).
|
|
|
|
In RAPL, the platform level settings are divided into domains for
|
|
fine grained control. These domains include processor package, DRAM
|
|
controller, CPU core (Power Plane 0), graphics uncore (Power Plane
|
|
1), etc.

This enables support for the idle injection framework. It

provides a way to force idle periods on a set of specified

CPUs for power capping. Idle period can be injected

synchronously on a set of specified CPUs or alternatively
|
|
on a per CPU basis.
