[PATCH v6 0/3] Asus vivobook s15 improvements

[PATCH v6 0/3] Asus vivobook s15 improvements

[Maud Spierings via B4 Relay]

Improves several parts of the devicetree:
1. The eDP panel bindings
2. Add a lid switch
3. Add bluetooth and describe wlan (depends on [1])

A big part of the bluetooth/wifi patch was copied from [1] as it is
mostly boiler plate regulator definitions
[1]: https://lore.kernel.org/all/20241007-x1e80100-pwrseq-qcp-v1-0-f7166510ab17@linaro.org/

---
I seem to get a warning that the pci17cb vendor is undocumented (wlan)
I can find this compatible in
Documentation/devicetree/bindings/net/wireless/qcom,ath12k.yaml
But pci17cb doesn't really seem like a vendor name to me, I have ignored
this warning for now.

Changes in v6:
- Use the proper define for the pmic-gpio drive-strength in the panel
  driver patch
- Add a comment about the voltage to the pmic-gpio power-source in the
  panel driver patch
- Remove the alias for the not (yet) existing debug uart in the bt/wifi
  patch
- Remove output-low from the bt_en gpio in the bt/wifi patch
- Add wcn- prefix to the bt-en and wlan-en gpio node names in the
  bt/wifi patch
- Link to v5: https://lore.kernel.org/r/20241202-asus_qcom_display-v5-0-e0d3752ff71f@hotmail.com

Changes in v5:
- Fix the pinctrl-# definition in the wcn7850-pmu node in the
  bluetooth/wifi patch
- Link to v4: https://lore.kernel.org/r/20241125-asus_qcom_display-v4-0-61a4da162406@hotmail.com

Changes in v4:
- Fixed the pin parameters for the backlight enable pin
- Fixed the wcn_sw_en drive-strength, this was not in the acpi table I
  checked.
- Fixed the ordering of several nodes in the bluetooth/wifi patch
- Link to v3: https://lore.kernel.org/r/20241124-asus_qcom_display-v3-0-002b723b1920@hotmail.com

Changes in v3:
- Fixed commit message formatting (line wrapping)
- Fixed bad indentation (lid switch pinctrl)
- Fixed bluetooth addition and added wifi description
- Link to v2: https://lore.kernel.org/r/20241123-asus_qcom_display-v2-0-a0bff8576024@hotmail.com

Changes in v2:
- Add missing gpiokeys include in the lid switch patch
- Add depends on for the bluetooth patch
- Link to v1: https://lore.kernel.org/r/20241123-asus_qcom_display-v1-0-85a9ff9240aa@hotmail.com

[PATCH v6 1/3] arm64: dts: qcom: x1e80100-vivobook-s15: Use the samsung,atna33xc20 panel driver

[Maud Spierings via B4 Relay]

From: Maud Spierings <maud_spierings@hotmail.com>

The Asus vivobook s15 uses the ATNA56AC03 panel.
This panel is controlled by the atna33xc20 driver instead of the generic
edp-panel driver

The reason we haven't pushed these patches for CRD, T14s etc is that
unlike for QCP these two regulators are not actually present on the
mainboard, they are part of a soldered or removable M.2 card. You can
find this TODO in the commit message/patch on Johan's kernel tree:

https://github.com/jhovold/linux/commit/32cfeff737b0f9a2f8787d21a875e549a22e9e8b
https://github.com/jhovold/linux/commit/2a7fee4007670e2f0f7696eb9e992e74d3be460f

We haven't come to a conclusion yet how to model these M.2 cards
properly. Perhaps we should stop blocking this and merge this for all
the laptops as temporary solution to get Bluetooth running, but then we
should at least preserve the TODO comment block to make that clear:

	/*
	 * TODO: These two regulators are actually part of the removable M.2
	 * card and not the CRD mainboard. Need to describe this differently.
	 * Functionally it works correctly, because all we need to do is to
	 * turn on the actual 3.3V supply above.
	 */

@Konrad: Given that you acked this patch, do you have any opinion if we
should merge these with this open question?

Thanks,
Stephan

It is soldered down in the case of the asus vivobook s15 see:
https://laptopmedia.com/wp-content/uploads/2024/06/IMG_20240618_161453_1-scaled.jpg

I don't know if this regulator is underneath this metal shield or if it 
is actually separate on the board in this case.

But given that it is not a replaceable m.2 module isn't it kind of part 
of the mainboard anyway?

Anyways if it does come to having to add the TODO comment I'll fix it up 
in a v7

kind regards,

Also makes the lid switch work with OpenBSD.
