+Subject: ACPI: battery: Add device HID and quirk for Microsoft Surface Go 3
+
+From: Maximilian Luz <luzmaximilian@gmail.com>
+
+commit 7dacee0b9efc8bd061f097b1a8d4daa6591af0c6 upstream.
+
+For some reason, the Microsoft Surface Go 3 uses the standard ACPI
+interface for battery information, but does not use the standard PNP0C0A
+HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver
+as this seems to work well.
+
+Additionally, the power state is not updated immediately after the AC
+has been (un-)plugged, so add the respective quirk for that.

+Subject: ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU
+
+From: Werner Sembach <wse@tuxedocomputers.com>
+
+commit c844d22fe0c0b37dc809adbdde6ceb6462c43acf upstream.
+
+Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
+native and video interface. However the default detection mechanism first
+registers the video interface before unregistering it again and switching
+to the native interface during boot. This results in a dangling SBIOS
+request for backlight change for some reason, causing the backlight to
+switch to ~2% once per boot on the first power cord connect or disconnect
+event. Setting the native interface explicitly circumvents this buggy
+behaviour by avoiding the unregistering process.

+Subject: ACPI / x86: Work around broken XSDT on Advantech DAC-BJ01 board
+
+From: Mark Cilissen <mark@yotsuba.nl>
+
+commit e702196bf85778f2c5527ca47f33ef2e2fca8297 upstream.
+
+On this board the ACPI RSDP structure points to both a RSDT and an XSDT,
+but the XSDT points to a truncated FADT. This causes all sorts of trouble
+and usually a complete failure to boot after the following error occurs:
+
+ ACPI Error: Unsupported address space: 0x20 (*/hwregs-*)
+ ACPI Error: AE_SUPPORT, Unable to initialize fixed events (*/evevent-*)
+ ACPI: Unable to start ACPI Interpreter
+
+This leaves the ACPI implementation in such a broken state that subsequent
+kernel subsystem initialisations go wrong, resulting in among others
+mismapped PCI memory, SATA and USB enumeration failures, and freezes.
+
+As this is an older embedded platform that will likely never see any BIOS
+updates to address this issue and its default shipping OS only complies to
+ACPI 1.0, work around this by forcing `acpi=rsdt`. This patch, applied on
+top of Linux 5.10.102, was confirmed on real hardware to fix the issue.
