| 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 |
| - gpio-controller: |
| - #gpio-cells = <1>: twl6040 provides GPO lines. |
| - #clock-cells = <0>; twl6040 is a provider of pdmclk which is used by McPDM |
| - 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 and/or to mclk clock provider |
| - clock-names: Must be "clk32k" for the 32K clock and "mclk" for the MCLK. |
| |
| 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>; |
| }; |
| }; |
