revision history:
v2: (thanks Lucas)
* reorder and clean up defconfig changes
* use "dram" for the interconnect path name and document it
v1:
* link: https://lore.kernel.org/linux-arm-kernel/20201201100124.4676-1-martin.kepplinger@puri.sm/T/

From: Leonard Crestez <leonard.crestez@nxp.com>
Add initial support for dynamic frequency scaling of main NOC.
Make DDRC the parent of the NOC (using passive governor) so that the
main NOC is automatically scaled together with DDRC by default.
Support for proactive scaling via interconnect will come on top.

are probed and the bandwidth doesn't have to be kept at maximum anymore.

Hi Martin,
Thank you for sending the patches.

As you are sending this, i believe that it should have your signed-off
line (please check Documentation/process/submitting-patches.rst).
Also please give people some time to look into this (at least 1-2 weeks)
before submitting a new version.
Thanks,
Georgi

I hope that it's not just for testing, but using it.

sure, I just think that most people will use their own config for
production but that's a different story. I can rephrase.

There's a yaml conversion by Laurentiu for mxsfb in flight:

It's save to remove it as other Interconnect options are directly
dependant.

Ugh, my bad, it is not allowed to remove it. My review was too fast.
INTERCONNECT_IMX depends on it, so the INTERCONNECT must stay,
It is selected by TEGRA_MC which is independent here, so you should keep it.

Krzysztof

This does not pass the dtschema checks. Are you missing here any
dependencies?
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: interconnect@32700000: 'devfreq' does not match any of the regexes: 'pinctrl-[0-9]+'

Why are you removing this? Other boards are using it. I am actually
failing to understand this patch. Maybe it was meant to be sort of
cleanup, but such cleanups are usually done by the maintainers after
the merge window, as they lead to multiple conflicts with other patches.
I would suggest to just drop this patch.
Thanks,
Georgi

thanks for reviewing! Just to be clear: We're talking about defconfig,
so if I keep INTERCONNECT that means that I do `make savedefconfig`
which removes it (it's of course still enabled, just redundant in
defconfig output), and then *manually* add INTERCONNECT. That would
indicate that there's a Kconfig bug.
thanks,
martin

I don't get the point. You should not send the savedefconfig output as
is, without any adjustments and checks. You can run savedefconfig
because it nicely puts your entries in the proper place, but it's not
a bug that it removes features which we *want to keep*. Where is a
bug in Kconfig?
Best regards,
Krzysztof
