Texas Instruments TWL family |
|
|
|
The TWLs are Integrated Power Management Chips. |
|
Some version might contain much more analog function like |
|
USB transceiver or Audio amplifier. |
|
These chips are connected to an i2c bus. |
|
|
|
|
|
Required properties: |
|
- compatible : Must be "ti,twl4030"; |
|
For Integrated power-management/audio CODEC device used in OMAP3 |
|
based boards |
|
- compatible : Must be "ti,twl6030"; |
|
For Integrated power-management used in OMAP4 based boards |
|
- interrupts : This i2c device has an IRQ line connected to the main SoC |
|
- interrupt-controller : Since the twl support several interrupts internally, |
|
it is considered as an interrupt controller cascaded to the SoC one. |
|
- #interrupt-cells = <1>; |
|
|
|
Optional node: |
|
- Child nodes contain in the twl. The twl family is made of several variants |
|
that support a different number of features. |
|
The children nodes will thus depend of the capability of the variant. |
|
