Furthermore, no 685 power management functions are exposed, as those are handled by the 686 general ACPI drivers. 687 688 More information about this driver is available at 689 <http://memebeam.org/toys/ToshibaAcpiDriver>. 690 691 If you have a legacy free Toshiba laptop (such as the Libretto L1 692 series), say Y. 693 694config TOSHIBA_BT_RFKILL 695 tristate "Toshiba Bluetooth RFKill switch support" 696 depends on ACPI 697 depends on RFKILL || RFKILL = n 698 ---help--- 699 This driver adds support for Bluetooth events for the RFKill 700 switch on modern Toshiba laptops with full ACPI support and 701 an RFKill switch. 702 703 This driver handles RFKill events for the TOS6205 Bluetooth, 704 and re-enables it when the switch is set back to the 'on' 705 position. 706 707 If you have a modern Toshiba laptop with a Bluetooth and an 708 RFKill switch (such as the Portege R500), say Y. 709 710config TOSHIBA_HAPS 711 tristate "Toshiba HDD Active Protection Sensor" 712 depends on ACPI 713 ---help--- 714 This driver adds support for the built-in accelerometer 715 found on recent Toshiba laptops equipped with HID TOS620A 716 device. 717 718 This driver receives ACPI notify events 0x80 when the sensor 719 detects a sudden move or a harsh vibration, as well as an 720 ACPI notify event 0x81 whenever the movement or vibration has 721 been stabilized. 722 723 Also provides sysfs entries to get/set the desired protection 724 level and resetting the HDD protection interface. 725 726 If you have a recent Toshiba laptop with a built-in accelerometer 727 device, say Y. 728 729config TOSHIBA_WMI 730 tristate "Toshiba WMI Hotkeys Driver (EXPERIMENTAL)" 731 default n 732 depends on ACPI_WMI 733 depends on INPUT 734 select INPUT_SPARSEKMAP 735 ---help--- 736 This driver adds hotkey monitoring support to some Toshiba models 737 that manage the hotkeys via WMI events. 738 739 WARNING: This driver is incomplete as it lacks a proper keymap and the 740 *notify function only prints the ACPI event type value.
