[PATCH v3 0/2] Add i2c clock duty cycle property for setting minimum persentage of clock high

[Potin Lai <potin.lai.pt@gmail.com>]

Introducing i2c-clk-duty-cycle-min property for setting minimum persentage
of clock high. 

This driver will go through base clock divisor and calculate a set of
high/low clock with duty cycle applied. if driver could not find a suit
high/low clock set, then it will use default duty cycle (50%) recalculate.

LINK: [v2] https://lore.kernel.org/all/20220601041512.21484-1-potin.lai.pt@gmail.com/

changes v2 --> v3:
* discard the properties for manual setting, use duty cycle to calculate
  high/low clock.

changes v1 --> v2:
* update bt-bindings documentation
* use meaningful values for properties instead of acture value in register
