Roald Frederickx | 9be0fcb | 2010-07-20 15:19:39 -0700 | [diff] [blame] | 27 | * compal-laptop.c - Compal laptop support. |
Cezary Jackiewicz | 5411552 | 2008-06-09 16:22:22 -0700 | [diff] [blame] | 28 | * |
Roald Frederickx | 9be0fcb | 2010-07-20 15:19:39 -0700 | [diff] [blame] | 29 | * This driver exports a few files in /sys/devices/platform/compal-laptop/: |
| 30 | * wake_up_XXX Whether or not we listen to such wake up events (rw) |
| 31 | * |
| 32 | * In addition to these platform device attributes the driver |
| 33 | * registers itself in the Linux backlight control, power_supply, rfkill |
| 34 | * and hwmon subsystem and is available to userspace under: |
| 35 | * |
| 36 | * /sys/class/backlight/compal-laptop/ |
| 37 | * /sys/class/power_supply/compal-laptop/ |
| 38 | * /sys/class/rfkill/rfkillX/ |
| 39 | * /sys/class/hwmon/hwmonX/ |
| 40 | * |
| 41 | * Notes on the power_supply battery interface: |
| 42 | * - the "minimum" design voltage is *the* design voltage |
| 43 | * - the ambient temperature is the average battery temperature |
| 44 | * and the value is an educated guess (see commented code below) |
| 45 | * |
Cezary Jackiewicz | 5411552 | 2008-06-09 16:22:22 -0700 | [diff] [blame] | 46 | * |
| 47 | * This driver might work on other laptops produced by Compal. If you |
| 48 | * want to try it you can pass force=1 as argument to the module which |
| 49 | * will force it to load even when the DMI data doesn't identify the |
Roald Frederickx | 9be0fcb | 2010-07-20 15:19:39 -0700 | [diff] [blame] | 50 | * laptop as compatible. |
| 51 | * |
| 52 | * Lots of data available at: |
| 53 | * http://service1.marasst.com/Compal/JHL90_91/Service%20Manual/ |
| 54 | * JHL90%20service%20manual-Final-0725.pdf |
| 55 | * |
| 56 | * |
| 57 | * |
| 58 | * Support for the Compal JHL90 added by Roald Frederickx |
| 59 | * (roald.frederickx@gmail.com): |
| 60 | * Driver got large revision. Added functionalities: backlight |
| 61 | * power, wake_on_XXX, a hwmon and power_supply interface. |
| 62 | * |
| 63 | * In case this gets merged into the kernel source: I want to dedicate this |
| 64 | * to Kasper Meerts, the awesome guy who showed me Linux and C! |
