1 | Texas Instruments TWL6040 family |
| 2 | ||
| 5cbe786a PU |
3 | The TWL6040s are 8-channel high quality low-power audio codecs providing audio, |
| 4 | vibra and GPO functionality on OMAP4+ platforms. | |
| 37e13cec PU |
5 | They are connected ot the host processor via i2c for commands, McPDM for audio |
| 6 | data and commands. | |
| 7 | ||
| 8 | Required properties: | |
| 1fc74aef | 9 | - compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041 |
| 37e13cec PU |
10 | - reg: must be 0x4b for i2c address |
| 11 | - interrupts: twl6040 has one interrupt line connecteded to the main SoC | |
| 12 | - interrupt-parent: The parent interrupt controller | |
| 5cbe786a PU |
13 | - gpio-controller: |
| 14 | - #gpio-cells = <1>: twl6040 provides GPO lines. | |
| 37e13cec PU |
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 | ||
| 20 | Optional properties, nodes: | |
| 21 | - enable-active-high: To power on the twl6040 during boot. | |
| 68bab866 PU |
22 | - clocks: phandle to the clk32k clock provider |
| 23 | - clock-names: Must be "clk32k" | |
| 37e13cec PU |

| 25 | Vibra functionality | |
| 26 | Required 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 | ||
| 36 | Optional 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 | |
