1 Texas Instruments TWL6040 family
3 The TWL6040s are 8-channel high quality low-power audio codecs providing audio,
4 vibra and GPO functionality on OMAP4+ platforms.
5 They are connected ot the host processor via i2c for commands, McPDM for audio
9 - compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041
10 - reg: must be 0x4b for i2c address
11 - interrupts: twl6040 has one interrupt line connecteded to the main SoC
13 - #gpio-cells = <1>: twl6040 provides GPO lines.
14 - #clock-cells = <0>; twl6040 is a provider of pdmclk which is used by McPDM
15 - twl6040,audpwron-gpio: Power on GPIO line for the twl6040
17 - vio-supply: Regulator for the twl6040 VIO supply
18 - v2v1-supply: Regulator for the twl6040 V2V1 supply
20 Optional properties, nodes:
21 - enable-active-high: To power on the twl6040 during boot.
22 - clocks: phandle to the clk32k and/or to mclk clock provider
23 - clock-names: Must be "clk32k" for the 32K clock and "mclk" for the MCLK.
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
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
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
