[PATCH v6 00/15] 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

[PATCH v6 09/15] arm64: dts: qcom: sdm845-lg-judyln: Add firmware nodes, change path

[Paul Sajna]

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

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.
