-* TWL4030's Keypad Controller device tree bindings
-
-TWL4030'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.
-
-This binding is based on the matrix-keymap binding with the following
-changes:
-
- * keypad,num-rows and keypad,num-columns are required.
-
-Required SoC Specific Properties:
-- compatible: should be one of the following
-   - "ti,twl4030-keypad": For controllers compatible with twl4030 keypad
-      controller.
-- interrupt: should be one of the following
-   - <1>: For controllers compatible with twl4030 keypad controller.
-
-Example:
-	twl_keypad: keypad {
-		compatible = "ti,twl4030-keypad";
-		interrupts = <1>;
-		keypad,num-rows = <8>;
-		keypad,num-columns = <8>;

-Texas Instruments TWL family (twl4030) audio module
-
-The audio module inside the TWL family consist of an audio codec and a vibra
-driver.
-
-Required properties:
-- compatible : must be "ti,twl4030-audio"
-
-Optional properties, nodes:
-
-Audio functionality:
-- codec { }: Need to be present if the audio functionality is used. Within this
-	     section the following options can be used:
-- ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts
-		    from the start of the recorded sample (in ms)
--ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise
--ti,hs_extmute: Use external mute for HS pop reduction
--ti,hs_extmute_gpio: Use external GPIO to control the external mute
--ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the
-		      valid values.
-
-Vibra functionality
-- ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if
-		   missing or it is 0, the vibra functionality is disabled.
-
-Example:
-&i2c1 {
-	clock-frequency = <2600000>;
-
-	twl: twl@48 {
-		reg = <0x48>;
-		interrupts = <7>; /* SYS_NIRQ cascaded to intc */

-Texas Instruments TWL family (twl4030) reset and power management module
-
-The power management module inside the TWL family provides several facilities

-Required properties:
-- compatible : must be "ti,twl4030-power"

-- ti,use_poweroff: With this flag, the chip will initiates an ACTIVE-to-OFF or
