- 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";
- interrupts = <0 119 4>;
- interrupt-parent = <&gic>;
- twl6040,audpwron-gpio = <&gpio4 31 0>;
- vio-supply = <&v1v8>;
- v2v1-supply = <&v2v1>;
- enable-active-high;
- /* regulators for vibra motor */
- vddvibl-supply = <&vbat>;
- vddvibr-supply = <&vbat>;
- vibra {
- /* Vibra driver, motor resistance parameters */
- ti,vibldrv-res = <8>;
- ti,vibrdrv-res = <3>;
- ti,viblmotor-res = <10>;
- ti,vibrmotor-res = <10>;
