USB forced fast charge v2

Soft force mode has been added (= mode 2). In this mode fast charge will only kick in if no USB device is detected (as should be the case for wall/car chargers). Please note that in this case fast charge will NOT work on a USB 2.0 and 3.0 port on a computer ! Use sysfs interface to change behaviour : * /sys/kernel/fast_charge/force_fast_charge (rw) * * 0 - disabled (default) * 1 - substitute AC to USB charging always * 2 - substitute AC to USB charging only if no USB peripheral is detected For informational purposes I've also added a read-only sysfs file that indicates the current USB state : * /sys/kernel/fast_charge/USB_peripheral_detected (ro) * * 0 - No USB device currently attached * 1 - USB device currently attached Consider this beta, it needs testing ! USB forced fast charge v2 Soft force mode (2) is validated. Use sysfs interface to change behaviour : * /sys/kernel/fast_charge/force_fast_charge (rw) * * 0 - disabled (default) * 1 - substitute AC to USB charging always * 2 - substitute AC to USB charging only if no USB peripheral is detected For informational purposes I've also added a read-only sysfs file that indicates the current USB state : * /sys/kernel/fast_charge/USB_peripheral_detected (ro) * * 0 - No USB device currently attached * 1 - USB device currently attached For informational purposes I've also added a read-only sysfs file that indicates the USB port type : (new) * /sys/kernel/fast_charge/USB_porttype_detected (ro) * * The port type will be returned in clear text. USB forced fast charge v2 Corrected wrong detection of USB cable unplugged to reset USB_porttype_detected, just informational, so nothing important, but it was wrong nonetheless and needed correcting. Use sysfs interface to change behaviour : * /sys/kernel/fast_charge/force_fast_charge (rw) * * 0 - disabled (default) * 1 - substitute AC to USB charging always * 2 - substitute AC to USB charging only if no USB peripheral is detected For informational purposes I've also added a read-only sysfs file that indicates the current USB state : * /sys/kernel/fast_charge/USB_peripheral_detected (ro) * * 0 - No USB device currently attached * 1 - USB device currently attached For informational purposes I've also added a read-only sysfs file that indicates the USB port type : * /sys/kernel/fast_charge/USB_porttype_detected (ro) * * The port type will be returned in clear text. USB forced fast charge v2 /sys/kernel/fast_charge/USB_peripheral_detected returns clear text now as well. Use sysfs interface to change behaviour : * /sys/kernel/fast_charge/force_fast_charge (rw) * * 0 - disabled (default) * 1 - substitute AC to USB charging always * 2 - substitute AC to USB charging only if no USB peripheral is detected For informational purposes I've also added a read-only sysfs file that indicates the current USB state : * /sys/kernel/fast_charge/USB_peripheral_detected (ro) * * The state will be returned in clear text (Yes/No). For informational purposes I've also added a read-only sysfs file that indicates the detected USB port type : * /sys/kernel/fast_charge/USB_porttype_detected (ro) * * The port type will be returned in clear text. USB forced fast charge v2 Small correction, forgot to remove the old line of code. Use sysfs interface to change behaviour : * /sys/kernel/fast_charge/force_fast_charge (rw) * * 0 - disabled (default) * 1 - substitute AC to USB charging always * 2 - substitute AC to USB charging only if no USB peripheral is detected For informational purposes I've also added a read-only sysfs file that indicates the current USB state : * /sys/kernel/fast_charge/USB_peripheral_detected (ro) * * The state will be returned in clear text (Yes/No).
