input: synaptics_dsx_2.6: update driver to enable touch S332U 



Synaptics reference driver V2.6 is being cleaned up to enable touch
controller S332U. Add Kconfig and Makefile changes to enable Synaptics dsx
V2.6 driver's compilation.
Clean checkpatch errors.

Synaptics DSXV26 touch controller



Please add this description here: The Synaptics Touch controller is connected to the

host processor via I2C. The controller generates interrupts when the user touches

the panel. The host controller is expected to read the touch coordinates over I2C and

pass the coordinates to the rest of the system.



Required properties:



 - compatible		           : should be "synaptics,dsx-i2c".

 - reg			               : i2c slave address of the device.

 - interrupt-parent	           : parent of interrupt.

 - synaptics,irq-gpio	       : irq gpio.

 - synaptics,irq-flags         : irq flags.



Optional property:

 - vdd_ana-supply			   : digital voltage power supply needed to power device.

 - vcc_i2c-supply			   : analog voltage power supply needed to power device.

 - synaptics,pwr-reg-name	   : power reg name of digital voltage.

 - synaptics,bus-reg-name	   : bus reg name of analog voltage.

 - synaptics,irq-on-state      : status of irq gpio.

 - synaptics,cap-button-codes  : virtual key code mappings to be used.

 - synaptics,vir-button-codes  : virtual key code and the response region on panel.

 - synaptics,x-flip		       : modify orientation of the x axis.

 - synaptics,y-flip		       : modify orientation of the y axis.

 - synaptics,reset-delay-ms	   : reset delay for controller (ms), default 100.

 - synaptics,max-y-for-2d	   : maximal y value of the panel.



Example:

	i2c@78b7000 {

		status = "ok";

		synaptics@4b {

			compatible = "synaptics,dsx-i2c";

			reg = <0x4b>;

			interrupt-parent = <&tlmm>;

			interrupts = <65 0x2008>;

			vdd_ana-supply = <&pmtitanium_l17>;

			vcc_i2c-supply = <&pmtitanium_l6>;

			synaptics,pwr-reg-name = "vdd_ana";

			synaptics,bus-reg-name = "vcc_i2c";

			synaptics,irq-gpio = <&tlmm 65 0x2008>;

			synaptics,irq-on-state = <0>;

			synaptics,irq-flags = <0x2008>; /* IRQF_ONESHOT | IRQF_TRIGGER_LOW */

			synaptics,power-delay-ms = <200>;

			synaptics,reset-delay-ms = <200>;

			synaptics,max-y-for-2d = <1919>; /* remove if no virtual buttons */

			synaptics,cap-button-codes = <139 172 158>;

			synaptics,vir-button-codes = <139 180 2000 320 160 172 540 2000 320 160 158 900 2000 320 160>;

		};
