The ast2600 is a new generation of SoC from ASPEED.
The adc device in this generation adds some changes and features.
This patch series handles the changes below:
1. Define the new register fields.
2. Split into two individual IPs and each contains 8 voltage channels.
3. Remove the pre-scaler and extend the field length of the scaler.
4. Ref_voltage becomes configurable.
