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

- J721S2XSOMXEVM:

- J7200XSOMXEVM:

- AM62A-SKEVM:

- J784S4XEVM

Changes from v3:
https://lore.kernel.org/all/20230417154832.216774-1-eblanc@baylibre.com/
- Rebased on top of v6.5-rc1.
- Change pinctrl number for irq pin as wkup_pmx0 was split on some boards.
- Use already present wkup_i2c0 node instead of creating a new one.

Changes from v2:
https://lore.kernel.org/lkml/20230414112843.1358067-1-eblanc@baylibre.com/
- Change node name as per Krzysztof review.
- Add a fix for the interrupt range of wakeup gpio used by TPS6594 pmic
  on J784S4.
  The interruptions of the PMIC were not working before that.
- Remove dependencies on other patch series as that was a mistake, see
  https://lore.kernel.org/lkml/CRYY2V3HJ0CP.96JQ18PLZB3C@burritosblues/

Changes from 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- Remove some outdated comments.
- Add PMIC to J784S4 board.
- Compatible string modified to match dt-bindings.
- Add gpio-controller and gpio-cells properties.
