This patch serials make aspeed_adc.c can support ast2600.
In additional,
patch #6 is used to improve the adc accurate 
patch #7 is used to fix the clock issue in the original code.

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 (8):
  dt-bindings: iio: adc: rename the aspeed adc yaml
  dt-bindings: iio: adc: Binding ast2600 adc.
  iio: adc: aspeed: completes the bitfield declare.
  iio: adc: aspeed: Allow driver to support ast2600
  iio: adc: aspeed: Add func to set sampling rate.
  iio: adc: aspeed: Add compensation phase.
  iio: adc: aspeed: Fix the calculate error of clock.
  iio: adc: aspeed: Support battery sensing.
