[PATCH v2 0/4] arm64: dts: rockchip: enable further peripherals on ArmSoM Sige5

[Alexey Charkov]

Link up the CPU regulators for DVFS, enable WiFi and Bluetooth.

Different board versions use different incompatible WiFi/Bluetooth modules
so split the version-specific bits out into an overlay. Basic WiFi
functionality works even without an overlay, but OOB interrupts and
all Bluetooth stuff requires one.

My board is v1.2, so the overlay is only provided for it.

Changes in v2:
- Expand the commit message for the patch linking CPU regulators and add
  tags for stable (thanks Nicolas)
- Fix the ordering of cpu_b* nodes vs. combphy0_ps (thanks Diederik)
- Drop the USB patch, as Nicolas has already posted a more comprehensive
  series including also the Type-C stuff (thanks Nicolas)
- Pick up Nicolas' tags
- Split out board version specific WiFi/Bluetooth stuff into an overlay
- Link to v1: https://lore.kernel.org/r/20250603-sige5-updates-v1-0-717e8ce4ab77@gmail.com

[PATCH v2 1/4] arm64: dts: rockchip: list all CPU supplies on ArmSoM Sige5

[Alexey Charkov]

List both CPU supply regulators which drive the little and big CPU
clusters, respectively, so that cpufreq can pick them up.

Without this patch the cpufreq governor attempts to raise the big CPU
frequency under high load, while its supply voltage stays at 850000 uV.
This causes system instability and, in my case, random reboots.

With this patch, supply voltages are adjusted in step with frequency
changes from 700000-737000 uV in idle to 950000 uV under full load,
and the system appears to be stable.

While at this, list all CPU supplies for completeness.

[PATCH v2 2/4] arm64: dts: rockchip: add SDIO controller on RK3576

[Alexey Charkov]

RK3576 has one more SD/MMC controller than are currently listed in its
.dtsi, with the missing one intended as an SDIO controller. Add the
missing node (tested with the onboard WiFi module on ArmSoM Sige5 v1.2)

[PATCH v2 3/4] arm64: dts: rockchip: add version-independent WiFi/BT nodes on Sige5

[Alexey Charkov]

ArmSoM Sige5 uses a soldered-on WiFi/BT module with WiFi on SDIO and BT
on UART. However, board v1.1 uses a Realtek based BL-M8852BS2, while
v1.2 uses a Broadcom based BW3752-50B1. They use the same pins and
controllers, but require different DT properties to enable.

Thankfully, the WiFi part at least works without explicitly listing it in
the device tree, albeit without OOB interrupt functionality.

Add required device tree nodes that do not depend on the board version so
that at least the WiFi module can appear on the SDIO bus.

WiFi OOB interrupt and Bluetooth function support are not enabled here, as
they require module specific properties.

[PATCH v2 4/4] arm64: dts: rockchip: add overlay for the WiFi/BT module on Sige5 v1.2

[Alexey Charkov]

Add support for the Broadcom based WiFi/Bluetooth module (BW3752-50B1)
found in ArmSoM Sige5 boards version 1.2. This includes SDIO connected
WiFi with OOB interrupt support, as well as UART connected Bluetooth
with its respective interrupts.

PCM support for Bluetooth SCO audio is left out for now. It is connected
to SAI2 in M0 pin mode in case someone needs to enable it.

Note that v1.1 boards used a Realtek based module which is incompatible
with these DT nodes, so v1.1 would need a different overlay.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

N.B.: these are unrelated to my series, and fixed by Nicolas' patch at
[1], already in -next.

Applied, thanks!

[4/4] arm64: dts: rockchip: add overlay for the WiFi/BT module on Sige5 v1.2
      commit: a8cdcbe6a9f64f56ee24c9e8325fb89cf41a5d63

Patch 1 as fix for v6.16

I've also fixed the wifi@1 node in the overlay - which was using
spaces instead of tabs.

Thanks Heiko! It's annoying that YAML doesn't like tabs, so copying
from binding examples is not a universally good idea :)

By the way, is there any tool that helps catch those?

Best regards,

checkpatch.pl would be the tool to do that, but I'm not sure it handles
this at this time.

I also only saw things when I looked at the patch in "mcedit", because
it nicely distinguishes between tabs and spaces :-) .

In vim, ``:set list`` makes them visible as well.
