MAX77759 PMIC is used in Pixel 6 and 6 Pro (Oriole/Raven) boards.
One of the functions of the MAX77759 PMIC is a battery charger. This
patchset introduces a driver for this function. One of the unique
features of this charger driver is that it works with a USB input where
the Type-C controller is TCPCI based.

Changes to the board files will follow soon once this patchset is reviewed.

For reference to the MAX77759 MFD based patchset (present in upstream):
https://lore.kernel.org/all/20250509-max77759-mfd-v10-0-962ac15ee3ef@linaro.org/ (local)

Dependency list:
Patch 5 depends on Patch 4 which depends on Patch 3.

Changes in v5:
- Use linear_range library instead of reinventing it. (André Draszik)
  - This requires a selector_max value so modified mfd/max77759.h to
    include it for CHGCC and CHG_ILIM.
  - Removed "reviewed-by" for Patch 3 (mfd) due to above
- Use asnyc probe type. (André Draszik)
- Retry mechanism for psy_work. (André Draszik)
- Minor nits (André Draszik):
  - Use named initializers for instantiating structs.
  - Use static qualifier for `psy_name` variable.
  - Refactor if-else ladder to remove else handling if return in prior
    "if" loop.
  - Remove redundant `unlikely`.
- Link to v4: https://lore.kernel.org/r/20260121-max77759-charger-v4-0-694234c8ded1@google.com (local)

Changes in v4:
- Removed a stray tabspace in mfd/max77759.h. (André Draszik)
- Fixed the following issues in Patch 4/5 (André Draszik):
  - Re-order Kconfig entry
  - Refactored to not use global variable
  - Use of clamp() to clamp values instead of duplicating logic
  - Return IRQ_NONE for unhandled irqs or error conditions
  - Remove debug messages in irq handler
  - Refactor code to use dev_err_probe in *_init_irqhandler()
  - Remove unneeded irq_flags
  - Check return values of regmap ops
  - Other nits like newlines, not using greedy init, using print stmnts
- Link to v3: https://lore.kernel.org/r/20251227-max77759-charger-v3-0-54e664f5ca92@google.com (local)

Changes in v3:
- Had incorrectly folded the charger sub-device with the pmic parent.
  Corrected it. (Krzysztof Kozlowski)
- Link to v2: https://lore.kernel.org/r/20251218-max77759-charger-v2-0-2b259980a686@google.com (local)

Changes in v2:
- Fold charger binding in maxim,max77759-charger.yaml to its parent
  node. (Krzysztof Kozlowski)
- Renamed regulator supplier & consumer. (Krzysztof Kozlowski & Heikki
  Krogerus)
- Removed explicit setting of irq trigger types in max77759 driver.
  (André Draszik & Krzysztof Kozlowski)
- Complete bit definitions for IRQ registers. (André Draszik)
- Consolidate all bit definitions for charger IP in mfd/max77759.h.
  (André Draszik)
- Modify the handling of charger IRQs such that regmap IRQ chip handles
  masking, de-mux and acking of interrupts. (André Draszik)
- Remove unused macro definitions relating to Charger modes in tcpci
  maxim driver (André Draszik)
- Add dependency on Regulator class in Kconfig definition for max77759
  chg. (Kernel Test Robot)
- Link to v1: https://lore.kernel.org/r/20251123-max77759-charger-v1-0-6b2e4b8f7f54@google.com (local)
