[PATCH v3 00/11] arm64: dts: qcom: sdm845-lg-{common, judyln}: Improve HW support in dts

[Paul Sajna]

Rollup of improved hardware support via devicetree for LG G7 ThinQ 
(judyln) from sdm845-mainline kernel fork

Notably, this patch-series enables full DRM acceleration and wifi,
among other small improvements in individual commits

after this patch-series the main things that remain to be worked
on include touchscreen, audio, and modem.

Depends upon panel driver patch-series https://lore.kernel.org/all/20250910-judyln-panel-v1-1-825c74403bbb@postmarketos.org/T/#r9a976ca01e309b6c03100e984a26a0ffc2fe2002

Changes in v3:
- change firmware paths to lowercase 'lg' (matching dt-bindings)
- fix signoffs
- add wifi dmesg to commit message
- remove regulator-always-on from ibb
- remove framebuffer
- remove msm ids
- don't continue commit subject into commit messages
- split bluetooth node
- add sbu uart details to commit message

- Link to v2: https://lore.kernel.org/r/20250916-judyln-dts-v2-0-5e16e60263af@postmarketos.org

Changes in v2:
- sort at the start
- drop unnecessary labels
- drop unnecessary gmu
- multi-led
- split fb-panel changes
- expand upon firmware commit message
- use qcom,calibration-variant instead of
  qcom,ath10k-calibration-variant
- change firmware paths to include "LG"
- remove framebuffer reservation
- add lab/ibb

- Link to v1: https://lore.kernel.org/r/20250913-judyln-dts-v1-0-23b4b7790dce@postmarketos.org

[PATCH v3 02/11] arm64: dts: qcom: sdm845-lg-common: Add uarts and Bluetooth

[Paul Sajna]

uart9 is debug serial on USB SBU1/2

UART RX is SBU1 and UART TX is SBU2 of the USB-C port).
1.8V Logic Level
Tested using pololu usb07a https://www.pololu.com/product/2585
and CH340 USB-UART

uart6 is bluetooth

Add bluetooth firmware path

[PATCH v3 06/11] arm64: dts: qcom: sdm845-lg-judyln: Add firmware nodes, change path

[Paul Sajna]

Add paths for Qualcomm firmware, including:
ipa, modem, bluetooth, venus, gpu

Enable adsp and cdsp nodes since their firmware is present

GPU and bluetooth are confirmed working, others may need more
testing/fixes

But regardless they will need the firmware paths specified here
and firmware added upstream before they will work, so might as well
get started on it now.

Paths changed to qcom/sdm845/lg/judyln

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

Could you read back register 0xd000+0x45 (LED_SRC_SEL) on downstream
and make sure the value matches upstream?

A msm8998 kernel fork I have laying around on my computer always seems
to write '1' in there (which it claims corresponds to VPH_PWR as input)

Allowing the same current for flash (brief on/off for night photos)
and LED (flashlight which you normally toggle through quick settings)
sounds no less than suspicious

This patch will allow any values between 4.6 V and 6.0 V to
be set on your phone, with the kernel defaulting to 4.6 V at
boot and staying there until (if?) any driver requests that to
change.

Your panel probably expects a *very* specific pair of voltages
and any deviation may cause unpredictable consequences, including
magic smoke if you happen to go over a certain limit.

You should most likely hardcode that specific expected voltage here

Perhaps this only exists in the postmarketos tree, but it definitely exists, and doesn't work without it. I'll remove it for upstreaming for now but hopefully someone sorts that out. upstream.

I think I'll probably just drop this until a bunch of other stuff is upstreamed. mdss is totally broken on mainline, wi-fi doesn't work, fuel gauge is missing, etc. etc.

Please make sure that the parts you are sending upstream are actually
working on the upstream tree. Otherwise somebody might try running
upstream without extra patches and be surprised about it not working.

The patchseres in question was submitted in 2020 and got rejected. Since
that time we have added support for machine-specific firmware-N.bin, so
Kalle's suggestion can now be implemented easily.

Regarding the MDSS. Is it being solved by adding reset to the MDSS node?
Or are there any other issues?

Yes I'm referring to the reset / pmdomain issue. Joel Selvaraj is looking into it in the sdm845 tree. He said he tried doing what other SOCs did and it just got stuck in a reboot loop. More investigation required. Currently he's reverted the pmdomain commits in our tree.

If the series get resent, could you please add the boot messages from

I think, you can keep simple-framebuffer. It will be used by the initial
booting and then will be replaced with the MDSS.

What does it mean? Also are they board-specific or should they be a part

Downstream frequently further constraints the regulators. Could you
please check the boards's dts file and the drivers (SDE)?

Re: [PATCH v3 09/11] arm64: dts: qcom: sdm845-lg-common: Add camera flash

[Chris Brown]

850mA looks correct for the flash, whereas the flashlight/torch should
be 100mA based on
https://github.com/EmanuelCN/android_kernel_lge_sdm845/blob/U/arch/arm64/boot/dts/lge/sdm845-judy/sdm845-camera/sdm845-judy-camera.dtsi
i.e. led-max-microamp = <100000>;

Should I use the init-voltage for min and max microvolt?

Can "... we just ignore the return value of
ath10k_qmi_host_cap_send_sync() and move along"?

Unfortunately the firmware versions I've hit this problem on has gone
belly up when receiving this request, that's why I asked Amit to add a
flag to skip it.

That said, in the devices I've hit this I've managed to get newer
firmware working, which doesn't have either problem.

That's the pain behind it.

IDK if it's super related, but some phones have additional mechanisms
for detecting (particulary the secondary) SIM - any chance yours is a
dual-SIM and you can try using the other slot?

No such luck. 

I think the device might have a second sim slot shared with the sdcard (if I put it sideways in the sdcard tray, there seems to be a bit of a groove there).

But the sim is detected by qmicli in the main slot I was using before, ModemManager just can't tell if it's locked or not.

The SIM is not detected at all in the sideways sdcard slot.

I'm afraid I can't help then. The modem is online and probably expects
some different handling from MM and/or vendor specific magic
