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 series adds device tree nodes for TI TPS6594 PMICs found in the
following boards:

Changes from v7:
https://lore.kernel.org/all/[email protected]/
- (New Patches) Add support for SK boards that have TPS6594xx PMIC
present (J721E-SK and AM69-SK)
- Add DONOTMERGE defconfig patch to show test logs
Changes from v6:
https://lore.kernel.org/all/[email protected]/
- Modify patch series to include only patches not merged (J7)
- Add boot logs for all affected boards
Changes from v5:
https://lore.kernel.org/all/[email protected]
- Range-diff: http://0x0.st/H_fD.diff
- Reword the patch fixing interrupt ranges for mcu domain gpio intr, and
add Fixes: tag
- Also fix interrupt ranges for main domain gpio intr in the same patch
- Change pinctrl node names to end in -pins to fix dtbs_check warnings
- (New Patch) Enable TPS6594 in defconfig
Changes from v4:
https://lore.kernel.org/all/[email protected]/
- Range-diff: https://0x0.st/H_L7.diff
- Rebased on top of linux-next
- Fix min voltage on vdd_usb_3v3 regulator (ldo2) on j721e-som
- Use 3-hex-digit format for pinctrl values
Changes from v3:
https://lore.kernel.org/all/[email protected]/
- 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/[email protected]/
- 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/[email protected]/
- 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- Remove some outdated comments.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.

2.34.1
From: Esteban Blanc <[email protected]>
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.

2.34.1
This patch adds support for TPS6594 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.

These devices provide 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.
