2009-12-13mfd: Don't set mc13783 ADREFMODE for touch conversionsUwe Kleine-König
Setting ADREFMODE is utter nonsense, but that's hard to read out of the spec. Strange enough it's possible to read x and y values even when it's set. When unset you can get values not only for the axes, but also for contact resistance which allows the touch driver to report pressure values.

2009-12-13mfd: Near complete mc13783 rewriteUwe Kleine-König
This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.

2009-09-17mfd: Add Freescale MC13783 driverSascha Hauer
This driver provides the core Freescale MC13783 support. It registers the client platform_devices and provides access to the A/D converter. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
