1Texas Instruments TWL6040 family
2
3The TWL6040s are 8-channel high quality low-power audio codecs providing audio,
4vibra and GPO functionality on OMAP4+ platforms.
5They are connected to 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- gpio-controller:
13- #gpio-cells = <1>: twl6040 provides GPO lines.
14- #clock-cells = <0>; twl6040 is a provider of pdmclk which is used by McPDM
15- twl6040,audpwron-gpio: Power on GPIO line for the twl6040
16
17- vio-supply: Regulator for the twl6040 VIO supply
18- v2v1-supply: Regulator for the twl6040 V2V1 supply
19
20Optional properties, nodes:
21- enable-active-high: To power on the twl6040 during boot.
22- clocks: phandle to the clk32k and/or to mclk clock provider
23- clock-names: Must be "clk32k" for the 32K clock and "mclk" for the MCLK.
24
25Vibra functionality
26Required properties:
27- vddvibl-supply: Regulator for the left vibra motor
28- vddvibr-supply: Regulator for the right vibra motor
29- vibra { }: Configuration section for vibra parameters containing the following
30	     properties:
31- ti,vibldrv-res: Resistance parameter for left driver
32- ti,vibrdrv-res: Resistance parameter for right driver
33- ti,viblmotor-res: Resistance parameter for left motor
34- ti,viblmotor-res: Resistance parameter for right motor
35
36Optional properties within vibra { } section:
37- vddvibl_uV: If the vddvibl default voltage need to be changed
38- vddvibr_uV: If the vddvibr default voltage need to be changed
