-* Analog Devices AD7879(-1)/AD7889(-1) touchscreen interface (SPI/I2C)
-
-Required properties:
-- compatible			: for SPI slave, use "adi,ad7879"
-				  for I2C slave, use "adi,ad7879-1"
-- reg				: SPI chipselect/I2C slave address
-				  See spi-bus.txt for more SPI slave properties
-- interrupts			: touch controller interrupt
-- touchscreen-max-pressure	: maximum reported pressure
-- adi,resistance-plate-x	: total resistance of X-plate (for pressure
-				  calculation)
-Optional properties:
-- touchscreen-swapped-x-y	: X and Y axis are swapped (boolean)
-- adi,first-conversion-delay	: 0-12: In 128us steps (starting with 128us)
-				  13  : 2.560ms
-				  14  : 3.584ms
-				  15  : 4.096ms
-				  This property has to be a '/bits/ 8' value
-- adi,acquisition-time		: 0: 2us
-				  1: 4us
-				  2: 8us
-				  3: 16us
-				  This property has to be a '/bits/ 8' value
-- adi,median-filter-size	: 0: disabled
-				  1: 4 measurements
-				  2: 8 measurements
-				  3: 16 measurements
-				  This property has to be a '/bits/ 8' value
-- adi,averaging			: 0: 2 middle values (1 if median disabled)
-				  1: 4 middle values
-				  2: 8 middle values
-				  3: 16 values
-				  This property has to be a '/bits/ 8' value
-- adi,conversion-interval:	: 0    : convert one time only
-				  1-255: 515us + val * 35us (up to 9.440ms)
-				  This property has to be a '/bits/ 8' value
-- gpio-controller		: Switch AUX/VBAT/GPIO pin to GPIO mode
