23 | * msi-laptop.c - MSI S270 laptop support. This laptop is sold under | |
24 | * various brands, including "Cytron/TCM/Medion/Tchibo MD96100". | |
25 | * | |
4f5c791a LP |
26 | * Driver also supports S271, S420 models. |
27 | * | |
8c4c731a LP |
28 | * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/: |
29 | * | |
30 | * lcd_level - Screen brightness: contains a single integer in the | |
31 | * range 0..8. (rw) | |
32 | * | |
33 | * auto_brightness - Enable automatic brightness control: contains | |
34 | * either 0 or 1. If set to 1 the hardware adjusts the screen | |
35 | * brightness automatically when the power cord is | |
36 | * plugged/unplugged. (rw) | |
37 | * | |
38 | * wlan - WLAN subsystem enabled: contains either 0 or 1. (ro) | |
39 | * | |
40 | * bluetooth - Bluetooth subsystem enabled: contains either 0 or 1 | |
41 | * Please note that this file is constantly 0 if no Bluetooth | |
42 | * hardware is available. (ro) | |
43 | * | |
44 | * In addition to these platform device attributes the driver | |
45 | * registers itself in the Linux backlight control subsystem and is | |
46 | * available to userspace under /sys/class/backlight/msi-laptop-bl/. | |
47 | * | |
48 | * This driver might work on other laptops produced by MSI. If you | |
49 | * want to try it you can pass force=1 as argument to the module which | |
50 | * will force it to load even when the DMI data doesn't identify the | |
51 | * laptop as MSI S270. YMMV. | |
