+Kernel driver toshiba_haps
+Toshiba HDD Active Protection Sensor
+====================================
+
+Author: Azael Avalos <coproscefalo@gmail.com>
+
+
+0. Contents
+-----------
+
+1. Description
+2. Interface
+3. Accelerometer axes
+4. Supported devices
+5. Usage
+
+
+1. Description
+--------------
+
+This driver provides support for the accelerometer found in various Toshiba
+laptops, being called "Toshiba HDD Protection - Shock Sensor" officialy,
+and detects laptops automatically with this device.
+On Windows, Toshiba provided software monitors this device and provides
+automatic HDD protection (head unload) on sudden moves or harsh vibrations,
+however, this driver only provides a notification via a sysfs file to let
+userspace tools or daemons act accordingly, as well as providing a sysfs
+file to set the desired protection level or sensor sensibility.
+
+
+2. Interface
+------------
+
+This device comes with 3 methods:
+_STA - Checks existence of the device, returning Zero if the device does not
+ exists or is not supported.
+PTLV - Sets the desired protection level.
+RSSS - Shuts down the HDD protection interface for a few seconds,
+ then restores normal operation.
+
+Note:
+The presence of Solid State Drives (SSD) can make this driver to fail loading,
+given the fact that such drives have no movable parts, and thus, not requiring
+any "protection" as well as failing during the evaluation of the _STA method
+found under this device.
+
+
+3. Accelerometer axes
+---------------------
+
+This device does not report any axes, however, to query the sensor position
+a couple HCI (Hardware Configuration Interface) calls (0x6D and 0xA6) are
+provided to query such information, handled by the kernel module toshiba_acpi
+since kernel version 3.15.
+
+
+4. Supported devices
+--------------------
+
+This driver binds itself to the ACPI device TOS620A, and any Toshiba laptop
+with this device is supported, given the fact that they have the presence of
+conventional HDD and not only SSD, or a combination of both HDD and SSD.
+
+
+5. Usage
+--------
+
+The sysfs files under /sys/devices/LNXSYSTM:00/LNXSYBUS:00/TOS620A:00/ are:
+protection_level - The protection_level is readable and writeable, and
+ provides a way to let userspace query the current protection
+ level, as well as set the desired protection level, the
+ available protection levels are:
+ 0 - Disabled | 1 - Low | 2 - Medium | 3 - High
+reset_protection - The reset_protection entry is writeable only, being "1"
+ the only parameter it accepts, it is used to trigger
+ a reset of the protection interface.
