Furthermore, no 675 power management functions are exposed, as those are handled by the 676 general ACPI drivers. 677 678 More information about this driver is available at 679 <http://memebeam.org/toys/ToshibaAcpiDriver>. 680 681 If you have a legacy free Toshiba laptop (such as the Libretto L1 682 series), say Y. 683 684config TOSHIBA_BT_RFKILL 685 tristate "Toshiba Bluetooth RFKill switch support" 686 depends on ACPI 687 depends on RFKILL || RFKILL = n 688 ---help--- 689 This driver adds support for Bluetooth events for the RFKill 690 switch on modern Toshiba laptops with full ACPI support and 691 an RFKill switch. 692 693 This driver handles RFKill events for the TOS6205 Bluetooth, 694 and re-enables it when the switch is set back to the 'on' 695 position. 696 697 If you have a modern Toshiba laptop with a Bluetooth and an 698 RFKill switch (such as the Portege R500), say Y. 699 700config TOSHIBA_HAPS 701 tristate "Toshiba HDD Active Protection Sensor" 702 depends on ACPI 703 ---help--- 704 This driver adds support for the built-in accelerometer 705 found on recent Toshiba laptops equipped with HID TOS620A 706 device. 707 708 This driver receives ACPI notify events 0x80 when the sensor 709 detects a sudden move or a harsh vibration, as well as an 710 ACPI notify event 0x81 whenever the movement or vibration has 711 been stabilized. 712 713 Also provides sysfs entries to get/set the desired protection 714 level and resetting the HDD protection interface. 715 716 If you have a recent Toshiba laptop with a built-in accelerometer 717 device, say Y. 718 719config TOSHIBA_WMI 720 tristate "Toshiba WMI Hotkeys Driver (EXPERIMENTAL)" 721 default n 722 depends on ACPI_WMI 723 depends on INPUT 724 select INPUT_SPARSEKMAP 725 ---help--- 726 This driver adds hotkey monitoring support to some Toshiba models 727 that manage the hotkeys via WMI events. 728 729 WARNING: This driver is incomplete as it lacks a proper keymap and the 730 *notify function only prints the ACPI event type value.
