Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input subsystem updates from Dmitry Torokhov:

 - a big update from Mauro converting input documentation to ReST format

 - Synaptics PS/2 is now aware of SMBus companion devices, which means
   that we can now use native RMI4 protocol to handle touchpads, instead
   of relying on legacy PS/2 mode.

 - we removed support from BMA180 accelerometer from input devices as it
   is now handled properly by IIO

 - update to TSC2007 to corretcly report pressure

 - other miscellaneous driver fixes.

+* Microchip AR1020 and AR1021 touchscreen interface (I2C)
+
+Required properties:
+- compatible		: "microchip,ar1021-i2c"
+- reg			: I2C slave address
+- interrupt-parent	: the phandle for the interrupt controller
+- interrupts		: touch controller interrupt
+
+Example:
+
+	touchscreen@4d {
+		compatible = "microchip,ar1021-i2c";
+		reg = <0x4d>;
+		interrupt-parent = <&gpio3>;
+		interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
+	};
