MFD: TPS65910: Add support for TPS65911 device
The TPS65911 is the next generation of the TPS65910 family of 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.
