Subject: [PATCH 3/4] arm64: dts: rockchip: rename vcc5v0_usb30_host regulator for Cool Pi CM5 EVB

According to the schematic, this regulator is used both for USB30 and
USB20, so give it a more appropriate name.

I don't have the schematics, so I'll need you to answer this, but what
is the regulator called _in_ the schematics?

I.e. we want regulators to really be named the same as in the schematic
so people can look up thing from the dts in the schematics and the other
way around too.


Thanks
Heiko

There are two regulators called VCC50_USB_HOST1 and VCC50_USB_HOST2, and they are both controlled by GPIO1_D5
They both for two usb 2.0 hosts, not usb 30, the schematics make
me a bit confused.

In that case, I'd say that renaming the regulator to vcc5v0_usb_host is
fine, but there should also be a comment in the board dts file that it's
actually two separate regulators.

Ah, that's very helpful.

How do you feel about this ? Or some other style like:
vcc5v0_usb_host1: vcc5v0_usb_host2:vcc5v0-usb-host-regulator {

I think we're using such a scheme in some places already, and
yes I really like going this way. So that the phandles follow the
schematic names and we can still grep for things.
