[KERNEL PATCH] Force AC (fast) Charging
This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This was a pretty big hit on some other devices so I figured I'd give it a shot for you guys. This allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
It is essentially a software version of the modified charge only usb cables.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
echo 0 > /sys/kernel/fast_charge/force_fast_charge
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
I have also implemented a toggle in IncrediControl (free) that will allow you to turn it on and off.
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
