Change since v4: dt-bindings: - Add clocks maxItems. - Rename the property to meet the property-units.yaml. - Add the description for the difference between adc0 and adc1. aspeed_adc.c: - Use new property name to get internal reference voltage: units from mv to uv. - Fix -Wnonnull warning caused by snprintf parameters. - Add suffix mv to the vref parameters. - Use ARRAY_SIZE instead of 32. - Add a reset action for ADC power down and Use devm_iio_device_register. - Fix typo error. - Separate the offset interface of ch7 when battery sensing enable 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.
