This series adds support for NX1 SoC, and the boards for Pro5 and NX1 SoCs.
Some of these boards have PCI endpoint.
NX1 SoC follows the same architecture as the other UniPhier SoCs, except
for the memory map.

Can you add more information here? When new SoCs get added, I
usually provide more than this in my own pull requests sending
the patches to Linus, so please add some background here, such as:
- is this a new SoC, or or something that has been around for a while
and only now gets upstreamed?
- What is the target market for this SoC? Are there any products
one can buy with it?
- What type of CPU cores does it use, or any other noteworthy
IP blocks that are relevant for its purpose?

I think these are usually just named 'phy@' instead of 'hs-phy@'

200MB of memory space is rather small, is there no 64-bit range?

Shouldn't there be an "msi-map" or "msi-parent" property pointing at
the GIC?

This advice is good for me.
I'll add some background for this SoC to the commit.

I see. Since it was adapted to other SoCs, I'll rename the node as well
in another patch.

Unfortunately, this SoC has only 190MB of PCIe memory space.

Since Designware PCIe receives an interrupt from GIC with interrupt-name "msi"
and passes the interrupt to the linear irq domain corresponding to MSI,
I think there is neither "msi-map" nor "msi-parent" properties.

Usually, you have the choice to use either the built-in
MSI logic of the PCIe controller, or the one built into the
GIC itself, assuming you have a modern enough GIC implemetation.
Using the GIC is preferred here, because otherwise you lose
all the benefits that MSIs offer, regarding latency and CPU
affinity.

I recognize ITS built into GICv3 can perform the parent of MSI.

I understand, however, unfortunately GIC-ITS (or something alternative)
isn't supported in this SoC, so I think it is difficult to use the GIC
itself as msi-parent.

Are you sure the clock is a property of a SoC? IOW, it is physically on
the SoC? If not, define entire clock or its frequency by boards.

I see. I'll change the node name with "clock".

Indeed. This shows an external oscillator outside of a SoC.
I'll consider to define the node or the property by board devicetree.

I see. I'll rename it to a generic name.
And also other system controller nodes in the same way.

I've done it, however, I missed the dt-binding document for the system
controller. I'll need to add a system controller's document before
this patch.

Need to rename to a generic name in the same way. After this as well.

Hmm, I've put "status" here according to the existing (uniphier's) DT policy
and this should rewrite the policy. Is there documentation somewhere that
recommends the order? Or, should I refer to previous comments?

I forgot to rename it and will rename to "interrupt-controller".

Hm, your decision (as arch maintainer) is then preferred, not mine.
Although it is quite unusual to find status, not reg, as the second
property.
compatible followed by reg is not documented anywhere, it's just the
most used style. And actually most sensible as it answers to questions
from highest importance to lowest:
1. What is this device? compatible
2. Where is it? Does it match unit address? reg
3. all other properties
4. Is it off or on? status as optional property
Best regards,
Krzysztof

Okay, however, if there are no examples where the second is "status",
I think it is better to follow the many descriptions for new additions.

I think it is reasonable to arrange the properties in order of importance.
I'll put "reg" second in this addition in the next.
