| 23 | * msi-laptop.c - MSI S270 laptop support. This laptop is sold under |
| 24 | * various brands, including "Cytron/TCM/Medion/Tchibo MD96100". |
| 25 | * |
Lennart Poettering | 4f5c791 | 2007-05-08 22:07:02 +0200 | [diff] [blame] | 26 | * Driver also supports S271, S420 models. |
| 27 | * |
Lennart Poettering | 8c4c731 | 2006-10-06 01:27:02 -0400 | [diff] [blame] | 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. |
