-Texas Instruments TWL6040 family
-
-The TWL6040s are 8-channel high quality low-power audio codecs providing audio
-and vibra functionality on OMAP4+ platforms.
-They are connected ot the host processor via i2c for commands, McPDM for audio
-data and commands.
-
-Required properties:
-- compatible : Must be "ti,twl6040";
-- reg: must be 0x4b for i2c address
-- interrupts: twl6040 has one interrupt line connecteded to the main SoC
-- interrupt-parent: The parent interrupt controller
-- 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.
-
-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
-

-&i2c1 {

- twl6040,audpwron-gpio = <&gpio4 31 0>;

- /* regulators for vibra motor */
- vddvibl-supply = <&vbat>;
