Fixing the devicetree of Rock 5 Model B (and possibly others)

Fixing the devicetree of Rock 5 Model B (and possibly others)

Since the introduction of the `of: property: fw_devlink: Fix stupid bug in remote-endpoint parsing` patch, an issue with the device-tree of the Rock 5 Model B has been detected. All the stable kernels (6.7.y and 6.8.y) work on the Orange Pi 5, which has the Rockchip RK3588S SoC (same as the RK3588, but less I/O basically). So, being an owner of only two SBCs which use the RK3588* SoC, it appears that the Rock 5 Model B's DT is incorrect.

I looked at the patch and tried several things, neither resulted in anything that would point me to the core issue. Then I tried this:

```
$ grep -C 3 remote-endpoint arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts

                port {
                        es8316_p0_0: endpoint {
                                remote-endpoint = <&i2s0_8ch_p0_0>;
                        };
                };
        };
--
                i2s0_8ch_p0_0: endpoint {
                        dai-format = "i2s";
                        mclk-fs = <256>;
                        remote-endpoint = <&es8316_p0_0>;
                };
        };
};
```

So, from a cursory look, the issue seems to be related to either the DT node for the audio codec or related to the es8316's binding itself. Though I doubt that the later is the issue because if that were the issue, _someone_ with a Pine64 Pinebook Pro would've raised alarms. So far, this seems to be related to the `rk3588-rock-5b.dts` and possibly with the `rk3588s-rock-5a.dts` too.

I would **love** to help but I'm afraid I device-trees are not something that I am at-all familiar with. That said, I am open to methods of debugging this issue to provide a fix myself.

I would have replied to the patch's link but unfortunately, I haven't yet setup neomutt and my email provider's web UI doesn't have a [straightforward] way to reply using the 'In-Reply-To' header, hence a new thread. Apologies for the inconvenience caused.

Ugh, just now noticing that I forgot to send the boot log captured over UART and forgot to disable sending the pubkey as an attachment.

The word wrap is broken because of course the web UI isn't mindful of that.

Sorry!

Could you, please, clarify a bit what's the actual issue you're
experiencing on your Rock 5B?

Pratham, can you reply to this please? I don't really understand what
your issue is for me to be able to help.

Also, can you give the output of <debugfs>/devices_deferred for the
good vs bad case?

Thanks,
Saravana

Hi,

I apologize for not replying. Somehow, I did not notice the reply from
Dragan. :(

Since this patch was applied, an issue in the Rock 5B's DT has been
unearthed which now results in the kernel being unable to boot properly.

Following is the relevant call trace from the UART capture:

[   21.595068] Call trace:

I can't provide you with requested output from the bad case, since the
kernel never moves past this to an initramfs rescue shell, but following
is the output from v6.8.1 (**with aforementioned patch reverted**).

# cat /sys/kernel/debug/devices_deferred
fc400000.usb    platform: wait for supplier /phy@fed90000/usb3-port
1-0022  typec_fusb302: cannot register tcpm port
fc000000.usb    platform: wait for supplier /phy@fed80000/usb3-port

It seems that v6.8.2 works _without needing to revert the patch_. I will
have to look into this sometime this week but it seems like
a8037ceb8964 (arm64: dts: rockchip: drop rockchip,trcm-sync-tx-only from rk3588 i2s)
seems to be the one that fixed the root issue. I will have to test it
sometime later this week.

This doesn't make a lot of sense. "remote-endpoint" shouldn't be
related to anything to do with psci cpuidle. I'm guessing something
else is failing much earlier in boot that's indirectly causing this
somehow? Can you please take a look at what's failing earlier and let
us know? Or see what driver probe is failing up to this point but used
to work in the good case.

Also, where is the dts file that corresponds to this board in upstream? Is it
arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts

Ok, once you find the patch that fixes things, let me know too.

I'm pretty new to this, "just starting". I'm not sure how to do that,
since the kernel doesn't really "move forward". I will verify if
a8037ceb8964 fixes it or not and get back by the end of this week.

FWIW the v6.8.1 kernel referenced above is definitely patched, since
upstream's Rock 5B DT does neither describe fusb302, nor the USB
port it is connected to.

We have a few Rock 5B in Kernel CI and upstream boots perfectly
fine:

https://lava.collabora.dev/scheduler/device_type/rk3588-rock-5b

So it could be one of your downstream patches, which is introducing
this problem.

I confirm that a8037ceb8964 fixed this issue for me. Now, v6.8.2+ boots on my Rock 5B,
with my distro's config and the arm64 defconfig.

No worries, I saw the serial console log file in one of your messages,
which actually provided the answer to my question. :)

There is an earlier bug report asking for a revert of that patch:

Is your problem maybe similar to the one above?

Ciao, Thorsten

> with the device-tree of the Rock 5 Model B has been detected. All the stable kernels (6.7.y and 6.8.y) work on the Orange Pi 5, which has the Rockchip RK3588S SoC (same as the RK3588, but less I/O basically). So, being an owner of only two SBCs which use the RK3588* SoC, it appears that the Rock 5 Model B's DT is incorrect.

Though I doubt that the later is the issue because if that were the issue, _someone_ with a Pine64 Pinebook Pro would've raised alarms. So far, this seems to be related to the `rk3588-rock-5b.dts` and possibly with the `rk3588s-rock-5a.dts` too.
