[PATCH v1 0/9] TI TPS6594 PMIC support for multiple TI EVMs

[Jerome Neanne]

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 fixes LDO voltage conversion for TPS6594 PMIC,
it adds support for its derivatives.

The features implemented are:
- Regulators
- WD disable

WD disable is not a watchdog driver implementation.
Watchdog is active by default causing a reboot even if not used.
This implementation allow to disable the watchdog at boot time.

Due to current situation with upstream u-boot dts,
this patch suite can be applied only after u-boot dts upstream is
resynched on latest Linux dts.

This should be applied on top of Linux patch series (for dts inheritence)

Tested on boards listed below (resynched manually on Linux 6.3 dts)

Supported boards:
- j721eXSOMXEVM:
Link: https://www.ti.com/tool/J721EXSOMXEVM
- AM62A-SKEVM:
Link: https://www.ti.com/tool/SK-AM62A-LP

basic tests:
=> pmic list
=> regulator list
=> regulator dev reg_name_to_be_tested
=> regulator info
=> regulator value
=> regulator value my_test_val
=> regulator value
Check WD reset is not happening when dip switch SW2 on GPIO8 is High.
