Furthermore, no 687 power management functions are exposed, as those are handled by the 688 general ACPI drivers. 689 690 More information about this driver is available at 691 <http://memebeam.org/toys/ToshibaAcpiDriver>. 692 693 If you have a legacy free Toshiba laptop (such as the Libretto L1 694 series), say Y. 695 696config TOSHIBA_BT_RFKILL 697 tristate "Toshiba Bluetooth RFKill switch support" 698 depends on ACPI 699 depends on RFKILL || RFKILL = n 700 ---help--- 701 This driver adds support for Bluetooth events for the RFKill 702 switch on modern Toshiba laptops with full ACPI support and 703 an RFKill switch. 704 705 This driver handles RFKill events for the TOS6205 Bluetooth, 706 and re-enables it when the switch is set back to the 'on' 707 position. 708 709 If you have a modern Toshiba laptop with a Bluetooth and an 710 RFKill switch (such as the Portege R500), say Y. 711 712config TOSHIBA_HAPS 713 tristate "Toshiba HDD Active Protection Sensor" 714 depends on ACPI 715 ---help--- 716 This driver adds support for the built-in accelerometer 717 found on recent Toshiba laptops equipped with HID TOS620A 718 device. 719 720 This driver receives ACPI notify events 0x80 when the sensor 721 detects a sudden move or a harsh vibration, as well as an 722 ACPI notify event 0x81 whenever the movement or vibration has 723 been stabilized. 724 725 Also provides sysfs entries to get/set the desired protection 726 level and resetting the HDD protection interface. 727 728 If you have a recent Toshiba laptop with a built-in accelerometer 729 device, say Y. 730 731config TOSHIBA_WMI 732 tristate "Toshiba WMI Hotkeys Driver (EXPERIMENTAL)" 733 default n 734 depends on ACPI_WMI 735 depends on INPUT 736 select INPUT_SPARSEKMAP 737 ---help--- 738 This driver adds hotkey monitoring support to some Toshiba models 739 that manage the hotkeys via WMI events. 740 741 WARNING: This driver is incomplete as it lacks a proper keymap and the 742 *notify function only prints the ACPI event type value.
