Petr Cvek 7ade445c26 ARM: pxa: magician: Add support for ADS7846 touchscreen ... This patch adds a support for ADS7846 touchscreen driver. The basic functionality was tested, x_plate_ohms and y_plate_ohms were physically measured. The value pressure_max was empirically set to match the measured range, which is affected by x_plate_ohms and ADS samples. The value of keep_vref_on should be set. A tested model (T-Mobile MDA Compact PM10A) doesn't seem to use Vref pin as the input from an external source. On this model the unset keep_vref_on cause high jitter of measured values. SPI framing pin (gpio_cs) must be used in GPIO mode due to an incompatible autoframing of PXA27x controller and ADS7846 device.
