[PATCH 0/9] arm64: dts: qcom: x1: Add missing pinctrl for eDP HPD

[Stephan Gerhold]

At the moment, we indirectly rely on the boot firmware to set up the
pinctrl for the eDP HPD line coming from the internal display. If the boot
firmware does not configure the display (e.g. because a different display
is selected for output in the UEFI settings), then the display fails to
come up and there are several errors in the kernel log:

 [drm:dpu_encoder_phys_vid_wait_for_commit_done:544] [dpu error]vblank timeout: 80020041
 [drm:dpu_kms_wait_for_commit_done:524] [dpu error]wait for commit done returned -110
 [drm:dpu_encoder_frame_done_timeout:2715] [dpu error]enc40 frame done timeout
 ...

Fix this by adding the missing pinctrl for gpio119 for all the boards
supported upstream.

I ran into this issue on the X1E CRD while testing some things and had this
fix in my local tree for a while. Chris made a similar patch for the T14s
[1], this series fixes up all of the boards upstream.

I think this is common enough. Let's maybe push this into the SoC dtsi
instead of copying it to all devices?

I had it there before, but Johan commented on the patch set from Chris
that he would prefer to keep the potentially board-specific pinctrl out
of the SoC dtsi [1]. So I can either address his feedback or yours. :-)

There isn't really a convention for X1E either - we have a wild mix
where some pinctrl is defined in the SoC dtsi (UART, I2C, SDHCI, ...)
and others is copied for each board (e.g. PCIe).

The reason I chose this approach is that I didn't feel it is guaranteed
that the HPD pin has external pull down. It seems to be the case on most
devices, but in theory a device could maybe rely on the internal pull
down. Might be better to have it explicitly defined, the 5 additional
lines are not that much at the end.

I'm also fine with moving it. Perhaps Bjorn or Konrad could comment if
they would prefer to have the pinctrl template defined in the SoC dtsi?

Thanks,
Stephan

PCIe pinctrl is a part of SoC DTSI for SM8[4567]0.

I don't think anybody will use internal pull-down for this, it would be
too risky in case the eDP cable is bad. I have checked several laptops,
they use external pull-down or two MOSFETs.

For some reason it's not on X1E.

So are you suggesting to put just the "template" (the
edp-hpd-default-state node) into the SoC dtsi and keep the
pinctrl-0/pinctrl-names reference in the board DT, or to put everything
into the SoC dtsi? I'm not sure if there is a use case where there
wouldn't be any HPD connected to GPIO119.

Yes.

Still it's a board configuration (pretty much like PCIe config is).

Ok, thanks. I'm fine with either approach really (putting it entirely in
board DT or the template in SoC dtsi and reference in board DT). I'll
wait a couple more days for more opinions, otherwise I'll send a v2 with
the template moved to the SoC dtsi.

[PATCH 2/9] arm64: dts: qcom: x1-crd: Add missing pinctrl for eDP HPD

[Stephan Gerhold]

At the moment, we indirectly rely on the boot firmware to set up the
pinctrl for the eDP HPD line coming from the internal display. If the boot
firmware does not configure the display (e.g. because a different display
is selected for output in the UEFI settings), then the display fails to
come up and there are several errors in the kernel log:

 [drm:dpu_encoder_phys_vid_wait_for_commit_done:544] [dpu error]vblank timeout: 80020041
 [drm:dpu_kms_wait_for_commit_done:524] [dpu error]wait for commit done returned -110
 [drm:dpu_encoder_frame_done_timeout:2715] [dpu error]enc40 frame done timeout
 ...

Fix this by adding the missing pinctrl for gpio119 (func1/edp0_hot and
bias-disable according to the ACPI DSDT).

[PATCH 5/9] arm64: dts: qcom: x1e80100-dell-xps13-9345: Add missing pinctrl for eDP HPD

[Stephan Gerhold]

At the moment, we indirectly rely on the boot firmware to set up the
pinctrl for the eDP HPD line coming from the internal display. If the boot
firmware does not configure the display (e.g. because a different display
is selected for output in the UEFI settings), then the display fails to
come up and there are several errors in the kernel log:

Fix this by adding the missing pinctrl for gpio119 (func1/edp0_hot and
