The keyboard is already supported by the existing Linux kernel and drivers but the touchpad is not recognized. This patch adds the coded needed to bring full functionality to the touchpad. Note that these remotes use the vendor code for SMK even though they are Sony branded. Known limitations - The built-in accelerometers are not supported by these changes - When the Drag (Fn) key is used as a mouse button, the button is automatically released when the key begins repeating. There are two workarounds for this 1) Use the button behind the touchpad instead of the Drag (Fn) key or 2) Disable the key repeat functionality or increase the key repeat delay.
