i.MX31: Fix a couple oopses from r31528

2012-01-03T06:13:59+00:00

Enabled a PMIC event where it should be disabled. Used constant from wrong enum
to get sense bits (??) which messed up main charger detection.

Also remove an obsolete struct declaration.

i.MX31 - Dethreading operations continue

2012-01-02T18:32:35+00:00

Dispense with "pmic" thread and process PMIC events directly within ISR. Add
sense bit reading as part of the handling.

Gigabeat S: PMIC SPI improvement and bugfixes.

2011-12-18T10:41:43+00:00

Nick some aspects from the as3525 ascodec driver to improve throughput in
the beast's SPI communications by switching tranfer descriptors to the
caller's stack and getting rid of thread synchronization.

Fix a bug that suddenly became obvious that could permanently stall the SPI
driver because all data could be shifted out before the interrupt could get
serviced. In that case, it needs a kick to restart it. Should probably put
the SPI interrupt priority above DVFS.

A tweak to the event registration interface to simplify it.

i.MX31/Gigabeat S: Actually enable DPTC which can set optimal voltage for 528MHz. Requires an SPI and PMIC interface rework because of the low-latency needs for the DPTC to work best with minimal panicing. SPI can work with multitasking and asynchronously from interrupt handlers or normal code.

Gigabeat S (imx31): Begin voltage and frequency scaling code. For now, to avoid overdrive voltage, just lower core voltage to 1.35V since voltage scaling shouldn't be required for frequencies lower than 399 MHz (according to Freescale BSP, which set all working points to 1.35V for those frequencies). Perhaps battery life will improve as well (cross fingers :).

imx31/mc13783: Do some housekeeping with register macros, function names and other defines. No functional changes (except to alter a couple int priorities).

MC13783 PMIC: Make some defines more strictly correct-- interrupts, etc.

MC13783 cleanup. Remove functions proving themselves not so useful and add mc13783_write_masked which is pretty useful. Add an error code definition for invalid data.

Updated our source code header to explicitly mention that we are GPL v2 or

Correct an oopsy when finishing off the MC13783 header. No wonder ADC readings seemed a wee odd.
