Fix some typos and while at it also use "PS" as the name for the central "HOME" button on Sony controllers, this is how Sony itself calls it.

2013-10-15Input: clarify gamepad API ABS valuesDavid Herrmann
It wasn't really clear from the gamepad-API description how ABS values are mapped exactly. Clarify that negative is left/up and positive is right/down. Unfortunately, this means I screwed up the Wii U ProController ABI. Anyhow, this just means we continue to have 0 compatible gamepad drivers in the kernel. User-space needs to fix them up, anyway, as all other gamepads are also incompatible. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-08-20input: document gamepad API and add extra keycodesDavid Herrmann
Until today all gamepad input drivers report their data differently. It is nearly impossible to write applications for more than one device in a generic way. Therefore, this patch introduces a uniform gamepad API which will be used for all new drivers. Instead of mapping buttons by their labels, we now map them by position. This allows applications to work with any gamepad regardless of the labels on the buttons. Furthermore, we standardize the ABS_* codes for analog triggers and sticks. For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should be fairly obvious how to use. To avoid confusion, the action buttons now have BTN_EAST/SOUTH/WEST/NORTH aliases.
