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.
|
|
|
|
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";
