[PATCH 0/8] Fixing some dtbscheck warnings

[Heiko Stuebner]

Fixing dtbs-check warnings should be declared addictive, one starts
with one warning, then another one and then it's oh, I'll just fix
this "last" one over and over ;-)

We still have more, if others want to play too :-D .

[PATCH 1/8] arm64: dts: rockchip: fix i2c2 pinctrl-names property on anbernic-rg353p

[Heiko Stuebner]

We want to control pins, not beer mugs, so rename pintctrl-names to the
expected inctrl-names.

This was not affecting functionality, because the i2c2 controller
already had a set of pinctrl properties.

The expected clock-name is different (ext_clock -> extclk) and the wakeup
gpio properties are named differently when changing from vendor-tree to
mainline. So fix those to match the binding.

[PATCH 8/8] arm64: dts: rockchip: Remove #cooling-cells from fan on Theobroma boards

[Heiko Stuebner]

All Theobroma boards use a ti,amc6821 as fan controller.
It normally runs in an automatically controlled way and while it may be
possible to use it as part of a dt-based thermal management, this is
not yet specified in the binding, nor implemented in any kernel.

Newer boards already don't contain that #cooling-cells property, but
older ones do. So remove them for now, they can be re-added if thermal
integration gets implemented in the future.

You may not want to control beer, but me...

Thank you for the catch, not sure how this first happened but
subsequent instances are likely a cut and paste.

Re: [PATCH 3/8] arm64: dts: rockchip: Drop regulator-init-microvolt from rk3568-roc-pc

[Jonas Karlman]

Hi Heiko,

Mainline U-Boot is also a user of the regulator-init-microvolt prop,
and use it to help configure an initial voltage on regulators during
boot.

Mostly useful for regulators that has different min / max voltage and
is not enabled by default or set to an unexpected voltage on boot, e.g.
the typical npu regulator on rk356x defaults to 0.5v, yet needs to be
around 0.9v during npu probe.

Maybe a better option would be to try add the init property to the Linux
dt-bindning?

Jonas

This has been tripping the dt-binding check for a while and since we've 
somehow not linked the fan controller to cpufreq for thermal throttling 
just yet, this was essentially not used.

As far as I know, no DT we wrote for customers had that linked either, 
so I think this is the most straightforward way to handle this rather 
than documenting this properly in the dt-binding and making sure the 
kernel driver actually supports it. As said, we can always revisit this 
later on if need be.

Therefore,

FYI:

$ git grep supports-emmc arch/arm64/boot/dts/rockchip
arch/arm64/boot/dts/rockchip/px30-ringneck.dtsi:        supports-emmc;
arch/arm64/boot/dts/rockchip/rk3328-nanopi-r2s-plus.dts:

So there's a few more to remove it seems :)

According to "brcm,bluetooth.yaml", 'extclk' is deprecated in favor of
'txco', so it seems better to use that?
Same would be true for Rock960 boards (patch 6 of this series).

thanks for that catch. I mainly stumbled upon the "_" underscore, found the
clockname without but didn't take into account that there was a deprecated
flag set in the binding :-)

Doing research for another improvement, I stumbled upon this commit:

ebceec271e55 ("arm64: dts: rockchip: Fix Wifi/Bluetooth on ROCK Pi 4 boards")

with the following diff:

```
 	sdio_pwrseq: sdio-pwrseq {
 		compatible = "mmc-pwrseq-simple";
 		clocks = <&rk808 1>;
-		clock-names = "ext_clock";
+		clock-names = "lpo";
 		pinctrl-names = "default";
 		pinctrl-0 = <&wifi_enable_h>;
 		reset-gpios = <&gpio0 RK_PB2 GPIO_ACTIVE_LOW>;
```

But do read the full git commit message.

The corresponding bluetooth node had 'lpo' as new value for
'clock-names' though ... from "ext_clock", but it also changed
its compatible, so it's not the same. For details, see commit
f471b1b2db08 ("arm64: dts: rockchip: Fix Bluetooth on ROCK Pi 4 boards")

So it's possible the change needs to be more extensive.
And a Tested-by tag from someone with the board is probably a good idea.

The brcm,bluetooth binding is pretty clear, it's
txco - for an "external reference clock, not a crystal"
lpo - for a low power 32.768 kHz clock.

The rk808 and also the pmucru are both "not crystals", so I'll just go
with the "txco".

The hci_bcm driver also handles txco and extclk the same, so there won't
be a behaviour change with existing code.

Looks like that topic comes up regularly, last time in

https://lore.kernel.org/linux-arm-kernel/4519023.cEBGB3zze1@phil/

and that still is true. DT is not a configuration-space, and if needed those
properties should be in the -uboot.dtsi
