Question about Turbo Charging topic

I unfortunately don't own a Moto X, but I would like to ask for a little help.

I think, the Moto X has the following interface file (I got this from a CM source code):
/sys/devices/platform/msm_ssbi.0/pm8921-core/pm8921-charger/charge_rate

Could you please check which values this file gives by reading?
- if not on charger
- if on normal charger
- if on turbo charger

(easiest with adb: "adb shell cat /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8921-charger/charge_rate")

Is this file maybe linked into here?
/sys/class/power_supply/battery/charge_rate

Thank you in advance!
