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 39 40Example: 41&i2c1 { 42 twl6040: twl@4b { 43 compatible = "ti,twl6040"; 44 45 interrupts = <0 119 4>; 46 interrupt-parent = <&gic>; 47 twl6040,audpwron-gpio = <&gpio4 31 0>; 48 49 vio-supply = <&v1v8>; 50 v2v1-supply = <&v2v1>; 51 enable-active-high; 52 53 /* regulators for vibra motor */ 54 vddvibl-supply = <&vbat>; 55 vddvibr-supply = <&vbat>; 56 57 vibra { 58 /* Vibra driver, motor resistance parameters */ 59 ti,vibldrv-res = <8>; 60 ti,vibrdrv-res = <3>; 61 ti,viblmotor-res = <10>; 62 ti,vibrmotor-res = <10>; 63 }; 64 }; 65}; 66 67/include/ "twl6040.dtsi" 68
