[PATCH 01/13] ARM: multi_v7_defconfig: Select PHY_ROCKCHIP_INNO_USB2

[Otavio Salvador]

Select the CONFIG_PHY_ROCKCHIP_INNO_USB2 option by default, so that
USB can be functional on RV1108.

Hi Otavio,

Thanks for these patches. I don't have a reason to _not_ enable
systemd features, but would you mind providing a brief description of
what's not working without this change? Is it completely broken, or is
it just the random-UID featues that don't work, or something else?.
Useful for others to know what's expected to break if someone turns
them off, etc.

Also, I noticed you posted a series of 13 patches, which includes some
dts files for rv1108, some network driver changes and some of these
more generic defconfig changes. I would suggest that you split up your
patches into independent series where possible, especially when they
end up going to different subsystems. Providing suitable cover letters
for the series when you post them is also useful to help reviewers by
summarizing the series, including changes from last time it was
posted, etc. Please address it to the superset of patch receivers on
the series.

I'm asking for the cover letter because this time I was wondering if
there was a reason for the mix of patches so I went looking for it.
Maybe there is a need to group them together even though the
sub-series seem somewhat independent -- I can't tell from the way they
were posted.


Thanks!

-Olof

Thank you for your kindness reviewing this. I am not an experienced
Linux kernel contributor so I am going to do some mistakes during this
process.

We usually follow the required feature set listed on Gentoo wiki[1] as
it is usually up to date and avoids a lot of headaches for us when
dealing with boot issues with SystemD.

1. https://wiki.gentoo.org/wiki/Systemd#Kernel

Do you think mentioning where it has been taken from is enough?

I can certainly improve it for the next submission. Should I split
them all and tag them v2 to easy it?

[PATCH 03/13] net: stmmac: dwmac-rk: Allow the driver to probe when phy-supply is not present

[Otavio Salvador]

The phy-supply is an optional regulator, so we should not treat
as an error when phy-supply is not passed in the device tree.

This allows the dwmac-rk driver to probe when phy-supply is not
present in the dts.

applied for 4.21 after modifying the subject a bit and adding
a comment explaining that the rv1108 only has that rmii interface.

While the dwmac is definitly a big improvement over the arc-emac
it is still surprising that the gbit mac only gets a 100mbit phy interface.

Nope. That value represents the number of cores in the system.
As the rv1108 only has one core, that should likely stay as it is.

Also, it seems I only got patches 6-13 what happened to 1-5?

I see, I will drop it for v2.

looks ok, especially as the TRM I have doesn't list neither irqs :-)
But please explain the second Signed-off by Fabio?

If Fabio is the original author, the patch From should reflect that
and the Signed-off-by lines should be swapped. As it is now
I would expect Fabio being the one sending the patches.
Or is it supposed to be a "Co-developed-by:"?

please also document that new compatible string in

[PATCH 12/13] ARM: dts: rv1108: Pass the 'arm,cpu-registers-not-fw-configured' property

[Otavio Salvador]

Since firmware does not initialize  any of the generic timer CPU
registers pass the 'arm,cpu-registers-not-fw-configured' property as
suggested in Documentation/devicetree/bindings/timer/arm,arch_timer.txt.

This also aligns with other Rockchip SoC dtsi files.

[PATCH 13/13] ARM: dts: rv1108: Pass the 'clock-latency' property

[Otavio Salvador]

Like it is done on cpu nodes of other Rockchip SoCs, pass the
'clock-latency' property to the CPU node, so that cpufreq driver
can take the latency into account when switching frequencies.

applied for 4.21 after adapting the subject and moving the property
to its correct alphabetical position in the node.
