[PATCH v8 0/7] Add TPS6594 PMIC support on several boards

[Neha Malcom Francis]

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:
- J721EXSOMXEVM:

https://lore.kernel.org/all/20231122104513.2335757-1-n-francis@xxxxxx/
- (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/20230810-tps6594-v6-0-2b2e2399e2ef@xxxxxx/
- 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/20230809-tps6594-v5-0-485fd3d63670@xxxxxx
- 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/20230727130908.10656-1-eblanc@xxxxxxxxxxxx/
- 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/20230417154832.216774-1-eblanc@xxxxxxxxxxxx/
- 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@xxxxxxxxxxxx/
- 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@xxxxxxxxxxxx/
- 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- Remove some outdated comments.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.
