In order to operate correctly twl6040 needs correct
interrupt configuration.
The slave drivers (vibra, and ASoC codec) will refuse
to probe, if the interrupt configuration is not correct.

TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.

TPS65911 adds new interrupt sources, as well as two new registers
to handle them, one for interrupt status and one for interrupt
masking. The added irqs are:

-VMBCH2 - Low and High threshold
-GPIO1-8 - Rising and falling edge detection
-WTCHDG - Watchdog interrupt
-PWRDN	- PWRDN reset interrupt

The code should handle these new registers only when the chip
version is TPS65911.

PMIC chips. It adds a few features:

- Watchdog Timer
- PWM & LED generators
- Comparators for system control status

It also adds a set of Interrupts and GPIOs, among other things.

The driver exports a function to identify between different
versions of the tps65910 family, allowing other modules to
identify the capabilities of the current chip.
