From 360f0f39d0c58432574655008ec8dd15e52e1e8d Mon Sep 17 00:00:00 2001 From: Azael Avalos Date: Tue, 25 Mar 2014 20:38:31 -0600 Subject: [PATCH] toshiba_acpi: Add keyboard backlight support Toshiba laptops equiped with an illuminated keyboard can operate in two different modes: Auto and FN-Z. The Auto mode turns on the led on keystrokes and automatically turns it off after some (configurable) time the last key was pressed. The FN-Z mode is used to toggle the keyboard led on/off by userspace. This patch adds support to set the desired KBD mode and timeout via sysfs, creates and registers toshiba::kbd_backlight led device whenever the mode is set to FN-Z. The acceptable values for mode are: 1 (Auto) and 2 (Fn-Z) The time values range are: 1-60 seconds Signed-off-by: Azael Avalos Signed-off-by: Matthew Garrett --- Reading git-format-patch failed
