-Subject: [PATCH] platform/x86: thinkpad_acpi: Add support for dual fan control
-
-This adds dual fan control for the following models:
-P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.
-
-Both fans are controlled together as if they were a single fan.
-
-Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.
-
-The patch is defensive, it adds only specific supported machines, and falls
-back to the old behavior if both fans cannot be controlled.
-
-Background:
-I tested the BIOS default behavior on my X1E gen2 and both fans are always
-changed together. So rather than adding controls for each fan, this controls
-both fans together as the BIOS would do.
-
-This was inspired by a discussion on dual fan support for the thinkfan tool
-(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
-verified on my machine.
-
-Thanks to GitHub users voidworker and civic9 for the earlier patches and
-BIOS IDs, and to users peter-stoll and sassman for testing the patch on
-their machines.
