Changes:
SAM:
- Enable performance modes on Surface Laptop 1 and 2.
- Support for D0-exit/D0-entry notifications, sent to the SAM
controller when suspending (D0-exit) or resuming (D0-entry) on
newer (gen. 7+) devices.
- Replace sysfs-based debug device with new debugfs-based debug
device.
- More internal restructuring and internal API changes.
- Some small bug fixes.
SAM-over-HID:
- Add ACPI support for SAM-over-HID. This allows setting dGPU power
on the Surface Book 1 via ACPI calls.

Changes:
surface3-spi:
- Dropped this patch in favor of the surface3-touchscreen-dma-fix
patch (which is taken from the upstream DMA fix). For details, take
a look at the commit history of kernel repo linked below.
surface3-touchscreen-dma-fix:
- Added this patch as a successor to the dropped surface3-spi patch.
For details, take a look at the commit history of kernel repo linked
below.
Note: currently, this patch is available upstream only on v5.8,
v5.7, and v5.4 and not backported to any older LTS kernels. So,
this patch was backported from upstream commit ourselves.
