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 LP8764 are derivatives.

This should be applied on top of other patch series:
- https://lore.kernel.org/all/20230406075622.8990-1-jpanis@baylibre.com/
  For core MFD driver
- https://lore.kernel.org/lkml/20230414101217.1342891-1-eblanc@baylibre.com/
  For regulator driver

This serie adds device tree nodes for TI TPS6594 PMICs found in the
following boards:
- J721EXSOMXEVM:

Changes since v1:
https://lore.kernel.org/lkml/20230329142948.833800-1-eblanc@baylibre.com/
- Harmonize regulators names across the different boards
- Adjust AVS voltage range
- Remove some outdated comments

There is no dependency indeed. We thought that dt-bindings patch at least had
to be applied before this DT series even if it is not a 'dependency', the other
link was a mistake. I will remove these misleading links in next cover-letter.

Thanks for your time. Best regards,
