usb: pd: Exposing the Peak Current value of Fixed Supplies to user space
Exposing the value of the field as is.
The Peak Current value has to be interpreted as described
in Table 6-10 (Fixed Power Source Peak Current Capability)
of the USB Power Delivery Specification, but that
interpretation will be done in user space, not in kernel.
