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>; }; }; }; /include/ "twl6040.dtsi"
