1 Texas Instruments TWL6040 family
3 The TWL6040s are 8-channel high quality low-power audio codecs providing audio
4 and vibra functionality on OMAP4+ platforms.
5 They are connected ot the host processor via i2c for commands, McPDM for audio
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
15 - vio-supply: Regulator for the twl6040 VIO supply
16 - v2v1-supply: Regulator for the twl6040 V2V1 supply
18 Optional properties, nodes:
19 - enable-active-high: To power on the twl6040 during boot.
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
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
32 Optional 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
