+Description:
+               Allows userspace applications to set the configurable TGP offset on top of the base
+               TGP. Base TGP and max TGP and therefore the max cTGP offset are device specific.
+               Note that setting the maximum cTGP leaves no window open for Dynamic Boost as
+               Dynamic Boost also can not go over max TGP. Setting the cTGP to maximum is
+               effectively disabling Dynamic Boost and telling the device to always prioritize the
+               GPU over the CPU.

+               Reading this file returns the current configurable TGP offset.

+Description:
+               Allows userspace applications to choose the USB-C power distribution profile between
+               one that offers a bigger share of the power to the battery and one that offers more
+               of it to the CPU. Writing "charging"/"performance" into this file selects the
+               respective profile.
+
+               Reading this file returns the profile names with the currently active one in
+               brackets.
