[PATCH v4 0/6] Add TPS6594 PMIC support on several boards

[PATCH v4 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 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- Remove some outdated comments.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.

[PATCH v4 3/6] arm64: dts: ti: k3-j721e-som-p0: Add TP6594 family PMICs

[Esteban Blanc]

From: Jerome Neanne <jneanne@baylibre.com>

This patch adds support for TPS6594 PMIC family on wakup I2C0 bus.
Theses devices 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 v4 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 TPS6593 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.

Could you use 0x01c format instead of 0x1c, 
and similar format in other patches in this series too.  

Rest LGTM

I see, this pin is getting shared with OSPI-1 .
I think either OSPI or PMIC could be functional at one time ?

OSPI CS1 is not being used, so the corresponding entry under OSPI1 can be removed.
