*	mfd: revise locking for pcf50633 ADC	Paul Fertser	2009-09-17	1	-16/+16
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Current implementation is prone to races, this patch attempts to remove all but one (in pcf50633_adc_sync_read). The idea is that we need to guard the queue access only on inserting and removing items. If we insert and there're no more items in the queue it means that the last irq already happened and we need to trigger ADC manually. If not, then the next conversion will be triggered by the irq handler upon completion of the previous.

*	mfd: PCF50633 adc driver	Balaji Rao	2009-01-11	1	-0/+277
	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.
