[PATCH v3 0/6] Add TPS6594 PMIC support on several boards

[PATCH v3 0/6] Add TPS6594 PMIC support on several boards

[Esteban Blanc]

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:
  Link: https://www.ti.com/tool/J721EXSOMXEVM
- J721S2XSOMXEVM:
  Link: https://www.ti.com/tool/J721S2XSOMXEVM
- J7200XSOMXEVM:
  Link: https://www.ti.com/tool/J7200XSOMXEVM
- AM62A-SKEVM:
  Link: https://www.ti.com/tool/SK-AM62A-LP
- J784S4XEVM
  Link: https://www.ti.com/tool/J784S4XEVM

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- Remove some outdated comments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

Changes since 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/

[PATCH v3 5/6] arm64: dts: ti: k3-j784s4-evm: Add support for TPS6594 PMIC

[Esteban Blanc]

From: Jerome Neanne <jneanne@baylibre.com>

This patch adds support for TPS65933A PMIC on wkup I2C0 bus.
This device provides regulators (bucks and LDOs), but also
GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
which monitors the SoC error output signal, and a PFSM
(Pre-configurable Finite State Machine) which manages the
operational modes of the PMIC.

[PATCH v3 6/6] arm64: dts: ti: k3-am62a7-sk: Add support for TPS6593 PMIC

This patch adds support for TPS6593 PMIC on main I2C0 bus.
This device provides regulators (bucks and LDOs), but also
GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
which monitors the SoC error output signal, and a PFSM
(Pre-configurable Finite State Machine) which manages the
operational modes of the PMIC.
