FS#5639 - Improved battery life on X5 (switching off USBOTG)


this is a patch that switches off the M5636 USBOTG device on iAudio X5.
Battery drain is reduced by ca. 50mA. On a X5L this makes a runtime of typically
24 hours instead of the current 15 hours.

The patch is based on reverse engineering of the OF. Unwanted side effects can not
be excluded. USE AT YOUR OWN RISK.

Good work!

I took the liberty of adjusting your patch to the target tree concept. Please review and test, and then I will commit it.

Looks reasonable at a first glance. Nevertheless I'd like to check it. Will take a few days due to other obligations.

I checked it: patches fine, compiles fine and runs fine. Most important: the energy saving is as expected.

Revised version hereby approved!
