This patch serials make aspeed_adc.c can support ast2600 and backward
compatible.
RESEND due to miss some patches when sent patch v4.
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.
