Subject: [PATCH v1 0/3] TI TPS6594 PMIC support (RTC, pinctrl, regulators, device trees)

TPS6594 is a Power Management IC which provides regulators and others
features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC can
communicate through the I2C or SPI interfaces.
TPS6594 is the super-set device while TPS6593 and LP8764X are derivatives.

This series adds support to TI TPS6594 PMIC and its derivatives.

This should be applied on top of other patch series:
- https://lore.kernel.org/all/20230216114410.183489-1-jpanis@baylibre.com/
  For core MFD driver

The features implemented in this series are:
- RTC (child device)
- Pinmux/GPIO (child device)
- Regulator (child device)

RTC description:
The TPS6594 family has an RTC built-in, except for LP8764X.
It provides time and an alarm.

Pinmux/GPIO:
TPS6594 family has 11 GPIOs. Those GPIO can also serve different
functions such as I2C or SPI interface, watchdog disable functions.
The driver provides both pinmuxing for the functions and GPIO capability.

Regulator:
TPS6594/TPS6593: 5 BUCKs and 4LDOs
LP8764X: 4 BUCKs and no LDO
Bucks can be used in multipahse mode
