NAME

     valz -- Toshiba Programmable I/O controller for Dynabook series


SYNOPSIS

     valz* at acpi?


DESCRIPTION

     Toshiba Dynabook series computers provide HCI/SCI I/O controllers that
     handle various interface devices.  This special I/O controller is
     accessed by the ``GHCI'' ACPI method.  The valz driver provides some sup-
     port for it.

     The valz driver handles the following hot-keys:

           Fn+F9   Toggle internal touchpad and trackpoint.
           Fn+Tab  Toggle LCD backlight.

     The valz driver has only been tested on the Dynabook R63/PS and some Dyn-
     abook models from 2013 or later.
