- linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
    on GPIO bit changes. An array of up to 8 entries can be provided

    experiment to determine which bit corresponds to which input. Use

* Toshiba TC3589x multi-purpose expander

The Toshiba TC3589x series are I2C-based MFD devices which may expose the
following built-in devices: gpio, keypad, rotator (vibrator), PWM (for
e.g. LEDs or vibrators) The included models are:

- TC35890
- TC35892
- TC35893
- TC35894
- TC35895
- TC35896

Required properties:
 - compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
   "toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
 - reg : I2C address of the device
 - interrupt-parent : specifies which IRQ controller we're connected to
 - interrupts : the interrupt on the parent the controller is connected to
 - interrupt-controller : marks the device node as an interrupt controller
 - #interrupt-cells : should be <1>, the first cell is the IRQ offset on this
   TC3589x interrupt controller.

Optional nodes:

- GPIO
  This GPIO module inside the TC3589x has 24 (TC35890, TC35892) or 20
  (other models) GPIO lines.
 - compatible : must be "toshiba,tc3589x-gpio"
 - interrupts : interrupt on the parent, which must be the tc3589x MFD device
 - interrupt-controller : marks the device node as an interrupt controller
 - #interrupt-cells : should be <2>, the first cell is the IRQ offset on this
   TC3589x GPIO interrupt controller, the second cell is the interrupt flags
   in accordance with <dt-bindings/interrupt-controller/irq.h>. The following
   flags are valid:
   - IRQ_TYPE_LEVEL_LOW
   - IRQ_TYPE_LEVEL_HIGH
   - IRQ_TYPE_EDGE_RISING
   - IRQ_TYPE_EDGE_FALLING
   - IRQ_TYPE_EDGE_BOTH
 - gpio-controller : marks the device node as a GPIO controller
 - #gpio-cells : should be <2>, the first cell is the GPIO offset on this
   GPIO controller, the second cell is the flags.

- Keypad
  This keypad is the same on all variants, supporting up to 96 different
  keys. The linux-specific properties are modeled on those already existing
  in other input drivers.
 - compatible : must be "toshiba,tc3589x-keypad"
 - debounce-delay-ms : debounce interval in milliseconds
 - keypad,num-rows : number of rows in the matrix, see
   bindings/input/matrix-keymap.txt
 - keypad,num-columns : number of columns in the matrix, see
   bindings/input/matrix-keymap.txt
 - linux,keymap: the definition can be found in
   bindings/input/matrix-keymap.txt
 - linux,no-autorepeat: do no enable autorepeat feature.
 - linux,wakeup: use any event on keypad as wakeup event.

Example:

tc35893@44 {
	compatible = "toshiba,tc35893";
	reg = <0x44>;
	interrupt-parent = <&gpio6>;
	interrupts = <26 IRQ_TYPE_EDGE_RISING>;

		compatible = "toshiba,tc3589x-gpio";
		interrupts = <0>;

		interrupt-controller;
		#interrupt-cells = <2>;
		gpio-controller;
		#gpio-cells = <2>;
	};
	tc3589x_keypad {
		compatible = "toshiba,tc3589x-keypad";
		interrupts = <6>;
		debounce-delay-ms = <4>;
		keypad,num-columns = <8>;
		keypad,num-rows = <8>;
		linux,no-autorepeat;
		linux,wakeup;
