This patch serials make aspeed_adc.c can support ast2600 and backward
compatible.

Change since v3:
dt-bindings:
  - Fix properties:aspeed,int_vref_mv type error.

Change since v2:
dt-bindings:
  - Create a new dt-bindings for ast2600 adc
aspeed_adc.c:
  - Splits the patch for more details
  - Remove version enum and use the flags in model data to distinguish
  hardware feature
  - Support trimming data get and set.
  - Use devm_add_action_or_reset to simplify probe error handling.

Changes since v1:
dt-bindings:
  - Fix the aspeed,adc.yaml check error.
  - Add battery-sensing property.
aspeed_adc.c:
  - Change the init flow:
    Clock and reference voltage setting should be completed before adc
    engine enable.
  - Change the default sampling rate to meet most user case.
  - Add patch #8 to suppoert battery sensing mode.

Billy Tsai (15):
  dt-bindings: iio: adc: Add ast2600-adc bindings
  iio: adc: aspeed: completes the bitfield declare.
  iio: adc: aspeed: set driver data when adc probe.
  iio: adc: aspeed: Keep model data to driver data.
  iio: adc: aspeed: Refactory model data structure
  iio: adc: aspeed: Add vref config function
  iio: adc: aspeed: Set num_channels with model data
  iio: adc: aspeed: Use model_data to set clk scaler.
  iio: adc: aspeed: Use devm_add_action_or_reset.
  iio: adc: aspeed: Support ast2600 adc.
  iio: adc: aspeed: Fix the calculate error of clock.
  iio: adc: aspeed: Add func to set sampling rate.
  iio: adc: aspeed: Add compensation phase.
  iio: adc: aspeed: Support battery sensing.
  iio: adc: aspeed: Get and set trimming data.
