@ -4,11 +4,13 @@ Specifying interrupt information for devices
1) Interrupt client nodes
-------------------------
Nodes that describe devices which generate interrupts must contain an either an
"interrupts" property or an "interrupts-extended" property. These properties
contain a list of interrupt specifiers, one per output interrupt. The format of
the interrupt specifier is determined by the interrupt controller to which the
interrupts are routed; see section 2 below for details.
Nodes that describe devices which generate interrupts must contain an
"interrupts" property, an "interrupts-extended" property, or both. If both are
present, the latter should take precedence; the former may be provided simply
for compatibility with software that does not recognize the latter. These
properties contain a list of interrupt specifiers, one per output interrupt. The
format of the interrupt specifier is determined by the interrupt controller to
which the interrupts are routed; see section 2 below for details.
Example:
interrupt-parent = <&intc1>;

Kernel driver toshiba_haps
Toshiba HDD Active Protection Sensor
====================================
Author: Azael Avalos <coproscefalo@gmail.com>

-----------
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.
