# Apple MFi devices fast-charge support

The driver is only available inside the kernel itself as at the time it was

written, significant changes to the core USB sub-system were needed to make

it work. The driver itself was merged at the same time as the supporting

changes and cannot work on older kernels.

Exports a `charge_type` for supported Apple MFi devices, so that those

devices can be made to either trickle charge (500mA), or draw much more

current, as explained in the “USB Power Capability Vendor Request” section

of the [Accessory Design Guidelines for Apple Devices](https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf).

Note that an [earlier version of the guidelines](https://usermanual.wiki/Document/MFiAccessoryHardwareSpecificationR9NoRestriction.875543417.pdf) had a slightly different “API”.

Both documents are also available in the docs/ subdirectory.
