* nano2g: fix dangerous mutex in hold switchCástor Muñoz2017-02-04
| | | | | | | | | This is a quick patch to solve FS#13104, we can not disable the clickwheel LDO from within interrupt code, so for the moment we leave it enabled all the time, it is unknown how power comsumption is affected when the hold switch is locked.

* iPod Classic: use PMU interrupts to detect hold switchCástor Muñoz2016-05-26
| | | | | | | Finally the hold switch workaround is removed and it is detected in the same way as OF does. Change-Id: Iceac6ca48ffd131b8ee9f62ffdc2b3e30eb02042
* iPod Classic: clickwheel fixesCástor Muñoz2015-12-17
| | | | | | | | | | | | | | | | | | | | | | Uses GPIO.E2 (Request To Send) to detect the holdswitch status, it is a temporal workaround that seems to work on all models. Holdswitch status must be detected to drive low GPIO.E2 (RTS) and GPIO.E4 (Data Out) when the holdswitch is locked, otherwise battery life decreases about 25%. Holdswitch unlock action is detected by reading the HELLO message that the external wheel controller sends when it is powered on, this allows to quickly capture clickwheel activity after unlock. GPIO.E2 is also used in case the HELLO message is missed because the holdswitch was unlocked before Rockbox/bootloader starts. These 2 lines (RTS and DOUT) can not be used to transmit messages to the external clickwheel controller, not a problem, actually no messages are sent while normal operation, only at initialization stage.

* iPod Classic: Fix bidirectional clickwheel communication.Steffen Butzer2014-10-02
| | | | | | | | | | | | | | | | | | | This restores functionality that was broken in g#194 and committed as revision 7ec426e497daa1b4a6082bf4e4e3df687b11db44. Bidirectional communication is required to ask the clickwheel controller for the initial button state during boot. Otherwise our driver would only know about pressed buttons when the first change event is received, which is too late for e.g. prevention of USB connection during boot. This fix is also required to support the selection of OF, Rockbox, Disk Mode, etc. in the iPod Classic Rockbox bootloader.
