-Device tree bindings for Atmel capacitive touch device, typically
-an Atmel touch sensor connected to AtmegaXX MCU running firmware
-based on Qtouch library.
-
-The node for this device must be a child of a I2C controller node, as the
-device communicates via I2C.
-
-Required properties:
-
- compatible: Must be "atmel,captouch".
- reg: The I2C slave address of the device.
- interrupts: Property describing the interrupt line the device
- is connected to. The device only has one interrupt
- source.
- linux,keycodes: Specifies an array of numeric keycode values to
- be used for reporting button presses. The array can
- contain up to 8 entries.
-
-Optional properties:
-
- autorepeat: Enables the Linux input system's autorepeat
- feature on the input device.
-
-Example:
-
- atmel-captouch@51 {
- compatible = "atmel,captouch";
- reg = <0x51>;
- interrupt-parent = <&tlmm>;
- interrupts = <67 IRQ_TYPE_EDGE_FALLING>;

-* Samsung's Keypad Controller device tree bindings
-
-Samsung's Keypad controller is used to interface a SoC with a matrix-type
-keypad device. The keypad controller supports multiple row and column lines.
-A key can be placed at each intersection of a unique row and a unique column.
-The keypad controller can sense a key-press and key-release and report the
-event using a interrupt to the cpu.
-
-Required SoC Specific Properties:
-- compatible: should be one of the following
- - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad
- controller.
- - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad
- controller.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- interrupts: The interrupt number to the cpu.
-
-Required Board Specific Properties:
-- samsung,keypad-num-rows: Number of row lines connected to the keypad
- controller.
-
-- samsung,keypad-num-columns: Number of column lines connected to the
- keypad controller.
-
-- Keys represented as child nodes: Each key connected to the keypad
- controller is represented as a child node to the keypad controller
- device node and should include the following properties.
- - keypad,row: the row number to which the key is connected.
- - keypad,column: the column number to which the key is connected.
- - linux,code: the key-code to be reported when the key is pressed
- and released.
-
-- pinctrl-0: Should specify pin control groups used for this controller.
-- pinctrl-names: Should contain only one value - "default".
-
-Optional Properties:
-- wakeup-source: use any event on keypad as wakeup event.
- (Legacy property supported: "linux,input-wakeup")
-
-Optional Properties specific to linux:
-- linux,keypad-no-autorepeat: do no enable autorepeat feature.

-- interrupts: the interrupt of this touch controller and ADC2.
-- clocks: the root clock of touch controller and ADC2.
-- clock-names; must be "tsc" and "adc".
-- xnur-gpio: the X- gpio this controller connect to.
- This xnur-gpio returns to low once the finger leave the touch screen (The
- last touch event the touch controller capture).
-
-Optional properties:
-- measure-delay-time: the value of measure delay time.
- Before X-axis or Y-axis measurement, the screen need some time before
- even potential distribution ready.
- This value depends on the touch screen.
-- pre-charge-time: the touch screen need some time to precharge.
- This value depends on the touch screen.
-- touchscreen-average-samples: Number of data samples which are averaged for
- each read. Valid values are 1, 4, 8, 16 and 32.
