+Atmel PTC Subsystem
+
+The Atmel Peripheral Touch Controller subsystem offers built-in hardware
+for capacitive touch measurement on sensors that function as buttons, sliders
+and wheels.
+
+1) PTC Subsystem node
+
+Required properties:
+- compatible:  Must be "atmel,sama5d2-ptc"
+- reg: Address, length of the shared memory and ppp 
registers location
+   and length.
+- clocks:  Phandlers to the clocks.
+- clock-names: Must be "ptc_clk", "ptc_int_osc", "slow_clk".
+- #address-cells:  Must be one. The cell is the button or scroller id.
+- #size-cells: Must be zero.
+
+Example:
+   ptc@fc06 {
+   compatible = "atmel,sama5d2-ptc";
+   reg = <0x0080 0x1
+  0xfc06 0xcf>;
+   interrupts = <58 IRQ_TYPE_LEVEL_HIGH 7>;
+   clocks = <_clk>, <>, <>;
+   clock-names = "ptc_clk", "ptc_int_osc", "slow_clk";
+   #address-cells = <1>;
+   #size-cells = <0>;
+
+   [ child node definitions... ]
+   };
+
+2) Scroller / buttons subnodes
+
+Subnodes describe the kind of sensors the customer want to use. They have to be
+named according to their function: button, slider or wheel.
+
+2.1) Scroller subnodes
+
+Required properties:
+- reg: Id of the scroller, each id must be different.
+
+Example:
+   slider@0 {
+   reg = <0>;
+   };
+
+   wheel@1 {
+   reg = <1>;
+   };
+
+2.2) Button subnodes
+
+Required properties:
+- reg: Id of node used for the button, each id must be
+   different.
+- linux,keycode:   Key code of the button.
+
+Example:
+   button@8 {
+   reg = <8>;
+   linux,keycode = <2>;
+   };
+
+   button@9 {
+   reg = <9>;
+   linux,keycode = <3>;
