[v2,5/5] arm64: dts: qcom: sc7280: Add herobrine-r1

Commit Message

Doug Anderson Jan. 25, 2022, 10:44 p.m. UTC

Add the new herobrine-r1. Note that this is pretty much a re-design
compared to herobrine-r0 so we don't attempt any dtsi to share stuff
between them.

This patch attempts to define things at 3 levels:

1. The Qcard level. Herobrine includes a Qcard PCB and the Qcard PCB
   is supposed to be the same (modulo stuffing options) across
   multiple boards, so trying to define what's there hopefully makes
   sense. NOTE that newer "CRD" boards from Qualcomm also use
   Qcard. When support for CRD3 is added hopefully it can use the
   Qcard include (and perhaps we should even evaluate it using
   herobrine.dtsi?)
2. The herobrine "baseboard" level. Right now most stuff is here with
   the exception of things that we _know_ will be different per
   board. We know that not all boards will have the same set of eMMC,
   nvme, and SD. We also know that the exact pin names are likely to
   be different.
3. The actual "board" level, AKA herobrine-rev1.

NOTES:
- This boots to command prompt, but no eDP yet since eDP hasn't
  been added to sc7280.dtsi yet.
- This assumes LTE for now. Once it's clear how WiFi-only SKUs will
  work we expect some small changes.

Changes in v2:
- Herobrine compatible on one line, not two
- Wording change in comments for components enabled per-board
- Always sort "bias" above "drive-strength" in pinctrl.
- Properly sort "hub_en" pinctrl.
- Two comments moved from multiline to single line.
- Space after "/delete-property/"

Can we stop adding "qcom,sc7280" to the board compatible string? It
looks out of place. It's the compatible for the SoC and should really be
the compatible for the /soc node.

Sometimes '-regulator' is left out. Is that intentional? I suppose it
would be better if every node had regulator postfix, but it may be too
long of a node name?

I don't have any objections, but I feel like this is the type of thing
I'd like Bjorn to have the final say on. What say you, Bjorn?

Huh, you're right. No, it's not intentional. It looks like it was that
way on herobrine-rev0 too... It also looks like it's missing on
"pp3300-hub" on trogdor.

Happy to add "-regulator" in the herobrine / trogdor nodes that need
it. I'll probably do it as a follow-on patch if that works OK? Then I
can just clean them all up at once...

One practical case I can think of right away, where this matters is in
cpufreq-dt-plat.c where we blocklist qcom,sc7280.

I don't know if we rely on this in any other places, but I'm not keen on
seeing a bunch of board-specific compatibles sprinkled throughout the
implementation - it's annoying enough having to add each platform to
these drivers.

Bjorn

Looking at sc7180, grep only shows cpufreq-dt-plat.c

 $ git grep qcom,sc7180\" -- drivers
 drivers/cpufreq/cpufreq-dt-platdev.c:   { .compatible = "qcom,sc7180", },

Simplest solution would be to look at / and /soc for a compatible
string.

 $ git grep -W 'soc[^:]*{' -- arch/arm*/boot/dts/ | grep compatible |
grep -v "simple-bus"

doesn't show many hits. The first hit is "ti,omap-infra" which is
actually inside an soc node, but even then I don't see anything that
matches the cpufreq-dt-plat.c lists.

Good, then we handle all other platform specifics in drivers using
platform-specific compatibles.

You mean that / would contain the device's compatible and /soc the soc's
compatible? I'm afraid I don't see how this would help you - you still
need the compatible in the dts, just now in two places.


Either we leave it as is - which follows my interpretation of what the DT
spec says - or we (and the DT maitainers) agree that it shouldn't be
there (because this dtb won't run on any random qcom,sc7180 anyways) at
all.

Seems that some device trees have "/soc" and others "/soc@0". For at
least a little context, see commit a1875bf98290 ("arm64: dts: qcom:
sdm845: Add unit name to soc node"). Since (presumably) this would
only be for newer SoCs then I guess you should search for "/soc@0"?
...and then if we ever have a SoC that's not @0 then we would have to
iterate through all SoCs

I'm curious what part of the DT spec says that we should have the SoC
in there? I know I've always done it, but it's always just been
following the examples of what was done before. When talking about the
root node, I see this in the `devicetree-specification-v0.4-rc1` spec:

---

Specifies a list of platform architectures with which this platform is
compatible. This property can be used by operating systems in
selecting platform specific code. The recommended form of the property
value is: "manufacturer,model"

For example:
compatible = "fsl,mpc8572ds"

---

That doesn't say anything about putting the SoC there.


I would also note that I'd be at least moderately inclined to land
things as-is and deal with this in a follow-up patch, though I'm happy
to spin if that's what people agree upon too. This is not a new
problem and so it doesn't seem like it makes sense to glom dealing
with it into this patch series...

I noticed that you applied the first 4 patches in the series (thanks!)
but not this one. Are we waiting to get agreement on this before
landing? As per above, I think it'd be OK to land as-is and then I'm
happy to do a follow-up patch to clean this up since this isn't a new
issue. Having this patch outstanding makes it a little confusing with
the other cleanup patches that I'm posting... ;-)

Thanks!

I didn't hear anything and I was sending a new version of the cleanup
patch series, so I:

* Added this last patch to the end of the cleanup series.

* Addressed the "-regulator" suffix issue that Stephen pointed out.

* Didn't remove the SoC compatible from the top-level node in this
patch, but added follow-on patches in the series that do it.

Hopefully that looks good to everyone. I removed both of Stephen's and
Matthias's review tags from the v3 version.

Yes. We can probably just use of_find_node_by_name(NULL, "soc") instead
though and then if there are multiple soc nodes in the future we can
iterate over all the soc nodes with for_each_of_allnodes_from() and make
this logic more complicated. I'd rather not implement any of that
complicated logic until we need to though.

I'd like / to contain the board compatible string and /soc to contain
the SoC's compatible string. The two strings are different. In this case
the board compatible at the root would be "google,trogdor-lazor" and the
soc node compatible would be "qcom,sc7180".

Sure. Hopefully DT maintainers can chime in here.

As you say, this dtb won't run on any random board that has a
qcom,sc7180 SoC placed on the PCB so having it in the root node
compatible is redundant at the least.
