11ad14f86a TPS65911: Add support for added GPIO lines
GPIO 1 to 8 are added for TPS65911 chip version. The gpio driver
now handles more than one gpio lines. Subsequent versions of the
chip family can add new GPIO lines with minimal driver changes.

a2974732ca TPS65911: Add new irq definitions
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.

a320e3c3d6 regulator: tps65911: Add new chip version
The tps65911 chip introduces new features, including changes in
the regulator module.

- VDD1 and VDD2 remain unchanged.
- VDD3 is now named VDDCTRL and has a wider voltage range.
- LDOs are now named LDO1...8 and voltage ranges are sequential,
  making LDOs easier to handle.

795570561c 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.

e3471bdc27 TPS65910: IRQ: Add interrupt controller
This module controls the interrupt handling for the tps chip. The
interrupt sources are the following:

- GPIO falling/rising edge detection
- Battery voltage below/above threshold
- PWRON signal
- PWRHOLD signal
- Temperature detection
- RTC alarm and periodic event

27c6750ec5 MFD: TPS65910: Add new mfd device for TPS65910
The TPS65910 chip is a power management IC for multimedia and handheld
devices. It contains the following components:

- Regulators
- GPIO controller
- RTC

The tps65910 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.
