Changes:
- Code cleanup and small fixes
- SAM:
- Fix timing issue when re-attaching the base on the Surface Book 3,
causing devices (e.g. battery) to not work properly after
re-attaching.

- kernel: 3ffb5d02de
- SAM: ff044c7463
Changes:
- Attempt to properly fix WiFi firmware crashes caused by power-save
mode and suspend. This aims to fix WiFi crashes without the need to
disable power-saving options and achieve better power consumption.
- Try to fix firmware wakeup issues.
- Try to reduce WiFi speed impact when Bluetooth is active.
- Fixes for P2P and AP modes. This should get miracast working.

Due to buildsystem limitations, we have previously disabled
CONFIG_DEBUG_INFO. This however, causes CONFIG_DEBUG_INFO_BTF to be
disabled, which in turn causes some warnings at boot when built with
CONFIG_BPF_PRELOAD. So let's also disable CONFIG_BPF_PRELOAD.
Changes:
- SAM:
- Add support for Surface Pro 7+
- Minor updates and fixes.
- IPTS:
- Send commands during shutdown again, this is needed on some devices
and readds the dependency on the MEI bus patch
- Flush buffers during shutdown, to prevent a timeout from CLEAR_MEM_WINDOW
- Added initial support for setting gen7 devices into multitouch
- Add firmware file override for ath10k wifi driver.

stability.
- Fix bug in PCI platform power state initialization preventing the
Intel LPSS driver from loading on 7th generation Surface devices.

- kernel: e8470c735d
Changes:
- SAM:
- Update DTX driver state after resume.
- Add DTX Documentation, misc. fixes, and cleanup.
- IPTS:
This implements a new and refined UAPI interface that should improve
stability during suspend and move some responsibility into userspace,
making the driver simpler.
It also fixes some sleep issues due to improper shutdown of the device.

We need to disable CONFIG_DEBUG_INFO for build with GitHub's Actions
because of memory requirements.

The PPA that is used for Ubuntu / Debian packages still doesn't have
anything higher than 5.6.7, so we can't update that at the moment.
