Furthermore, no 688 power management functions are exposed, as those are handled by the 689 general ACPI drivers. 690 691 More information about this driver is available at 692 <http://memebeam.org/toys/ToshibaAcpiDriver>. 693 694 If you have a legacy free Toshiba laptop (such as the Libretto L1 695 series), say Y. 696 697config TOSHIBA_BT_RFKILL 698 tristate "Toshiba Bluetooth RFKill switch support" 699 depends on ACPI 700 depends on RFKILL || RFKILL = n 701 ---help--- 702 This driver adds support for Bluetooth events for the RFKill 703 switch on modern Toshiba laptops with full ACPI support and 704 an RFKill switch. 705 706 This driver handles RFKill events for the TOS6205 Bluetooth, 707 and re-enables it when the switch is set back to the 'on' 708 position. 709 710 If you have a modern Toshiba laptop with a Bluetooth and an 711 RFKill switch (such as the Portege R500), say Y. 712 713config TOSHIBA_HAPS 714 tristate "Toshiba HDD Active Protection Sensor" 715 depends on ACPI 716 ---help--- 717 This driver adds support for the built-in accelerometer 718 found on recent Toshiba laptops equipped with HID TOS620A 719 device. 720 721 This driver receives ACPI notify events 0x80 when the sensor 722 detects a sudden move or a harsh vibration, as well as an 723 ACPI notify event 0x81 whenever the movement or vibration has 724 been stabilized. 725 726 Also provides sysfs entries to get/set the desired protection 727 level and resetting the HDD protection interface. 728 729 If you have a recent Toshiba laptop with a built-in accelerometer 730 device, say Y. 731 732config TOSHIBA_WMI 733 tristate "Toshiba WMI Hotkeys Driver (EXPERIMENTAL)" 734 default n 735 depends on ACPI_WMI 736 depends on INPUT 737 select INPUT_SPARSEKMAP 738 ---help--- 739 This driver adds hotkey monitoring support to some Toshiba models 740 that manage the hotkeys via WMI events. 741 742 WARNING: This driver is incomplete as it lacks a proper keymap and the 743 *notify function only prints the ACPI event type value.
