I missed some of the earlier bits of the thread here but why can't
we do
device based lookups?

I think we only have two choices for this:
1) Stick to the scheme where resources are declared at the device level,
such as they can be referenced by name in the sub-nodes (basically what
I did in this patch):
backlight {
compatible = "pwm-backlight";
...
backlight-supply = <&backlight_reg>;
power-on-sequence {
step@0 {
regulator = "backlight";
enable;
};
This would translate by a get_regulator(dev, "backlight") in the code
which would be properly resolved.
Yes, upon reflection, that scheme does make sense. I withdraw the
comments I made re: whether it'd be better to just stick the phandles
into the steps.
Right - having the phandles directly in the sequences has its merits,
but logically speaking resources are related to a device, so this
declarative approach is probably closer to reality anyway.
I will revise the patch according to all the feedback received and
submit a new version soon.
Thanks,
Alex.
