Subject: [PATCH v2 0/4] platform: arm64: thinkpad-t14s-ec: fixes and
 suspend support

I have a two fixes for the T14s Gen6 Snapdragon EC driver as well as
improved system suspend support. I've been using my Thinkpad with these
patches for a few weeks as daily driver doing regular system suspend and
things seem to run well.

If there is enough time after review the fixes are probably good
material for the 6.18 release cycle.

Changes in v2:
- Link to v1: https://patch.msgid.link/20251106-thinkpad-t14s-ec-improvements-v1-0-109548ae75c0@collabora.com
- Add dmesg call trace in first patch description
- Mention ECWS ACPI function in PM patch description
- Include linux/pm.h in second patch
- Mention Thinkpad ACPI driver behavior in last patch
