1Texas Instruments TWL6040 family
2
3The TWL6040s are 8-channel high quality low-power audio codecs providing audio
4and vibra functionality on OMAP4+ platforms.
5They are connected ot the host processor via i2c for commands, McPDM for audio
6data and commands.
7
8Required properties:
9- compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041
10- reg: must be 0x4b for i2c address
11- interrupts: twl6040 has one interrupt line connecteded to the main SoC
12- interrupt-parent: The parent interrupt controller
13- twl6040,audpwron-gpio: Power on GPIO line for the twl6040
14
15- vio-supply: Regulator for the twl6040 VIO supply
16- v2v1-supply: Regulator for the twl6040 V2V1 supply
17
18Optional properties, nodes:
19- enable-active-high: To power on the twl6040 during boot.

21Vibra functionality
22Required properties:
23- vddvibl-supply: Regulator for the left vibra motor
24- vddvibr-supply: Regulator for the right vibra motor
25- vibra { }: Configuration section for vibra parameters containing the following
26	     properties:
27- ti,vibldrv-res: Resistance parameter for left driver
28- ti,vibrdrv-res: Resistance parameter for right driver
29- ti,viblmotor-res: Resistance parameter for left motor
30- ti,viblmotor-res: Resistance parameter for right motor
31
32Optional properties within vibra { } section:
33- vddvibl_uV: If the vddvibl default voltage need to be changed
34- vddvibr_uV: If the vddvibr default voltage need to be changed
