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 |
|
|
|
