    driver
  - clean up some sparse warnings
  - Keep old dt-binding name
since v6:

    in-flight.
  - Adjusted code order and variable names to reduce the delta with
    the max31335

since v5:
  - change of maintainer
  - use adi,ti-diode property
  - deal with oscillator fail and releasing SWRST

since v4:
  - dt-binding: add enum value "2" to aux-voltage-chargable
  - dt-binding: remove adi,trickle-diode-enable
  - dt-binding: change description of trickle-resistor-ohms
  - dt-binding: reorder as in example schema
  - parse "wakeup-source" when irq not requested
  - remove limitation on max31328 irq and clockout
  - remove error and warning messages during trickle charger setup

since v3:

  - dt-binding: add new property "adi,trickle-diode-enable"
  - dt-binding: remove "wakeup-source"
  - use clear_bit instead of __clear_bit
  - use devm_of_clk_add_hw_provider instead of of_clk_add_provider
  - use chip_desc pointer as driver data instead of enum.

since v2:
  - add "break" to fix warning: unannotated fall-through

since v1:
  - dt-binding: update title and description
  - dt-binding: remove last example
  - drop watchdog support
  - support reading 12Hr format instead of forcing 24hr at probe time
  - use "tm_year % 100" instead of range check
  - refactor max313xx_init for readability
