[PATCH v2 0/7] Enable Bluetooth and WiFi on Fairphone (Gen. 6)

[PATCH v2 0/7] Enable Bluetooth and WiFi on Fairphone (Gen. 6)

[Luca Weiss]

Add the required bits to enable Bluetooth and WiFi on the Milos
SoC-based Fairphone (Gen. 6) smartphone.

Signed-off-by: Luca Weiss <luca.weiss@fairphone.com>
---
Changes in v2:
- Drop applied pd-mapper patch
- Add compatibles for wcn6755 with fallback to wcn6750 (wifi & bt)
- Rebase on linux-next
- Pick up one tag (discard the rest due to addition of wcn6755
  compatibles)
- Link to v1: https://lore.kernel.org/r/20260116-milos-fp6-bt-wifi-v1-0-27b4fbb77e9c@fairphone.com

[PATCH v2 1/7] regulator: dt-bindings: qcom,qca6390-pmu: Document WCN6755 PMU

[Luca Weiss]

Document the WCN6755 PMU using a fallback to WCN6750 since the two chips
seem to be completely pin and software compatible. In fact the original
downstream kernel just pretends the WCN6755 is a WCN6750.

[Luca Weiss]

In order to set the pinctrl for the individual CTS, RTS, TX and RX pins,
split up the pinctrl configuration into 4 nodes so that boards can set
some properties separately.

[PATCH v2 7/7] arm64: dts: qcom: milos-fairphone-fp6: Enable WiFi

[Luca Weiss]

Configure and enable the WiFi node, and add the required pinctrl to
provide the sleep clock from the PMK8550 (PMK7635) to WCN6755.

Thanks to Alexander Koskovich for helping with the bringup, adding
the missing pinctrl to make the WPSS stop crashing.

Hmm, if it's a sleep_clk, should it not be handled via the power
sequencer?

Thanks!

      https://git.kernel.org/broonie/regulator/c/b043657c35e5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
