| |
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.
