23 * msi-laptop.c - MSI S270 laptop support. This laptop is sold under
24 * various brands, including "Cytron/TCM/Medion/Tchibo MD96100".
26 * Driver also supports S271, S420 models.
28 * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/:
30 * lcd_level - Screen brightness: contains a single integer in the
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)
38 * wlan - WLAN subsystem enabled: contains either 0 or 1. (ro)
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)
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/.
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.
