Please don't take things off-list unless there is a really strong reason to do so. Sending things to the list ensures that everyone gets a chance to read and comment on things.
After contacting our HW RD, to support DVDD 1.8V not just SW config, also HW connections. To get only DVDD supply voltage is not enough to meet the HW design. The property seems indeed and need to be used by user's HW connection.
Can this property to be kept?
After thinking, This property name may be improper. I think this change depends on HW external circuit for lowv application. Currently, I'm modifying the V3 change, this property name also affect the property parsing code change. May I directly change the name to 'richtek,dvdd-lowv-application' and submit the patch v3?
I still don't understand why you wouldn't describe this through the regulator bindings, those exist to describe the physical supplies ont he board and their constraints.
Not to oppose your comment, from the initial idea, I'm just thinking 'how' to make the user easy to use. But if this way is more flexible, I'll change it to check the regulator voltage.
This will be put in patch v3. Thanks.
