[PATCH v8 0/8] imx25 adc and touchscreen driver

[Markus Pargmann <mpa@pengutronix.de>]

Hi,

welcome to the next round of the never ending series ;). The last version v7
was sent roughly 8 months ago. The first version at least 1.5 years ago.

This series adds two drivers for ADC and TSC of the imx25 and a MFD driver to
connect these.

Due to the larger changes in this version I had to remove some of the acks
again.

@Hartmut:
Thanks for your comments. I updated the drivers accordingly.

Changes in v8:
 - scale was defined as a shared property of the ADC although the scale can be
   different for each ADC channel. v8 fixes that.
 - Some smaller modifications of the code style in gcq code.
 - Redesign of the regulator handling in the gcq code. The driver does now
   handle regulators "vref-ext", "vref-xp" and "vref-yp" as positive voltage
   reference.  Also the calculation of the scale property based on these
   voltage reference regulators was fixed. The code now uses
   regulator_get_optional() to avoid dummy regulators.
 - The missing regulator_disable() was added.

 Thanks to Jürgen the time behavior of the units is now fixed and within specs:
 - Fixed clock rates for the whole unit regarding to the reference manual.
 - Fixed clock/time calculations for settling times in the touchscreen driver.

Best Regards,

Markus
