rockbox/firmware, branch 2048sp5

Fix a race condition in as3525 I2C driver caused by stacked ISRs.

2015-03-16T07:27:08+00:00

It was possible for interrupts of higher priority than the current IRQ
level to attempt to restart the interface while it was still active on
a transfer. The list modification also wasn't protected within the I2C
ISR itself.

Revert "usb_storage: make it a bit more correct"

2015-02-16T13:06:28+00:00

Clearly this was a stupid commit, no idea why I did that.

This reverts commit 074e911859a0d3464fde9b701b3cff712c5826e0.

2015-02-07T12:34:06+00:00

iBasso DX50/DX90: User selectable USB mode.

2015-02-02T21:43:46+00:00

Depends on http://gerrit.rockbox.org/r/#/c/1043/.

This patch adds a new setting in Settings -> General -> System: USB Mode.

Usable in Quickscreen and Shortcuts.

Possible settings are:
- Mass Storage: The default, on USB connect export the internal and external
drives as usual. Rockbox will exit gracefully in this case, since the internal
drive (/mnt/sdcard) is exported as mass storage device and Android prevents
Rockbox from continued execution.
- Charge Only: USB charge only, do not export the internal and external drives.
This will not close Rockbox.
- ADB: Enable the Android Debug Bridge. This will not close Rockbox.

Charge only and ADB are actually the same, since it is not yet established if
charge only is doable without adb and major hooks into Android.

This may be genric for Android based devices but is only enabled
