The 10 bits definition was the 8 bits one.

Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.

I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

The 'pcf50633_mbc_set_status' function is unused, so remove it.

The battery charger state machine switches into charging mode when
the battery voltage falls below 96% of a battery float voltage. But
the voltage drop in Li-ion batteries is marginal(1~2 %) till about
80% of its capacity - which means, after a BATFULL, charging won't
be restarted until 80%.

This work_struct function restarts charging at regular intervals to
make sure the battery doesn't discharge too much.

What the PCF05633 calls as a 'GPIO' is much more than the GPIO in the linux
sense and there are only 4 of them - which means, the gpiolib is not used
here.

This patch adds basic support for the PCF50633 ADC. The subtractive mode
is not supported yet.

Since we don't have adc subsystem, it currently lives in drivers/mfd.

This patch implements the core of the PCF50633 driver. This core driver has
generic register read/write functions and does interrupt management for its
sub devices.
