+Texas Instruments TWL6040 family
+
+The TWL6040s are 8-channel high quality low-power audio codecs providing audio,
+vibra and GPO functionality on OMAP4+ platforms.
+They are connected ot the host processor via i2c for commands, McPDM for audio
+data and commands.
+
+Required properties:
+- compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041
+- reg: must be 0x4b for i2c address
+- interrupts: twl6040 has one interrupt line connecteded to the main SoC
+- interrupt-parent: The parent interrupt controller
+- gpio-controller:
+- #gpio-cells = <1>: twl6040 provides GPO lines.
+- twl6040,audpwron-gpio: Power on GPIO line for the twl6040
+
+- vio-supply: Regulator for the twl6040 VIO supply
+- v2v1-supply: Regulator for the twl6040 V2V1 supply
+
+Optional properties, nodes:
+- enable-active-high: To power on the twl6040 during boot.
+- clocks: phandle to the clk32k clock provider
+- clock-names: Must be "clk32k"
+
+Vibra functionality
+Required properties:
+- vddvibl-supply: Regulator for the left vibra motor
+- vddvibr-supply: Regulator for the right vibra motor
+- vibra { }: Configuration section for vibra parameters containing the following
+ properties:
+- ti,vibldrv-res: Resistance parameter for left driver
+- ti,vibrdrv-res: Resistance parameter for right driver
+- ti,viblmotor-res: Resistance parameter for left motor
+- ti,viblmotor-res: Resistance parameter for right motor
+
+Optional properties within vibra { } section:
+- vddvibl_uV: If the vddvibl default voltage need to be changed
+- vddvibr_uV: If the vddvibr default voltage need to be changed
+
+Example:
+&i2c1 {
+ twl6040: twl@4b {
+ compatible = "ti,twl6040";
