Hi,
OrangePi 3 is somewhat different from these two boards (mostly it has a differnt
power tree). It doesn't use the AXP regulators that are defined in the
sun50i-h6-orangepi.dtsi in the same way.
For example:
- bldo3 (is turned always on in sun50i-h6-orangepi.dtsi but unused for opi3)
- cldo2 and cldo3 are unused on opi3 and have nothing to do with WiFi
- aldo3 is not for dram
- bldo1 on the other hand is for dram on opi3
- some other regulators are used for different/more functions and thus
named differntly
- USB id-det pin is differnt
- ...
OrangePi 3 is not a superset of what is defined in sun50i-h6-orangepi.dtsi.
So to base Orange Pi 3 dts on top of existing sun50i-h6-orangepi.dtsi I'd have
to first move some things out of the base dtsi to the OrangePi Lite2 and One
Plus board dts files, in order to have sun50i-h6-orangepi.dtsi only describe HW
that is *really* shared by these 2 boards and Orange Pi 3.
If I do that, I'd undefine all the axp805 regulator nodes and move the
configurations to each of the 3 board files. That will probably end up being
the least confusing and most maintainable. See axp81x.dtsi lines 86-144 for
what I mean.
What do you think? Is this acceptable to everyone?
regards,
o.
