[PATCH v2 0/7] Add support for ECS LIVA QC710 mini PC/devkit

[PATCH v2 0/7] Add support for ECS LIVA QC710 mini PC/devkit

[Val Packett]

v2:
* Added missing dt-bindings:vendor-prefixes patches
* Applied suggested cleanups and formatting
* Dropped power-on disable block
* Added qcom,uefi-rtc-info for the RTC
* Added qcom,calibration-variant for the WiFi
  * Board file sent: https://lists.infradead.org/pipermail/ath10k/2026-January/016719.html
* Added a comment about USB ports on the HS hub
* Picked up tags

Display output glitching and IOMMU faulting turned out to be a missing reset, fix in:
https://lore.kernel.org/all/20260120-topic-7180_dispcc_bcr-v1-0-0b1b442156c3@oss.qualcomm.com/

Also verified the usb_1_hsphy by reading registers in Windows with windbg.
Unsurprisingly they do match (it is the same system-in-package as aspire1..)

I initially silently ignored this patch because this is churn to deal
with such one liners. This should be squashed. But after talk with
Dmitry let's clarify.

If you target different trees, then:
1. Do not combine them into one patchset
2. If combining, do not mix the order like 1/7 goes to foo, 2/7 goes to
bar, 3/7 goes to foo again, 4/7 goes to bar again.

Make it easy for maintainers, so we won't spend time deciphering this or
acking multiple of such single liners (I asked this on mailing list
multiple times).

Best regards,
Krzysztof

Would it still work with <59 4>? 58 seems to not be related to a QUP,
rather as an audio MCLK output (would that be why +Nikita couldn't get
some sort of audio working on his aspire1? That DT has it reserved too)

here you do:

drive-strength
bias-

here you do the inverse

(the former is preferred/more common)

otherwise

FWIW according to aspire1 schematic GPIO 57 is codec mclk (which is
implemented and works perfectly, only DMIC connected to the soc
instead of said codec is broken); GPIO 58~62 are NC with a note
"Finger Printer" [sic] near them. There is no bracket annotation to
associate the note to specific pin range, but it's smack in the
middle of 58~62 range and from the fact that 63 (speaker amp bclk)
and pretty much every other pin later is also used, I guessed all 5
are actually reserved. It's possible that one of them is not
actually reserved by the firmware but probably not the source of
aspire1 issues (the dmic is connected to lpass tlmm anyway) or
perhaps they reserved 58 to be an interrupt input for the fp, or
something like that...
