This series introduces a mouse uclass and provides drivers for two types
of mouse: sandbox (using SDL) and USB (potentially usable on any
hardware).

Note that this was written four years ago, so may need some tweaking. I
have tidied it up so that it builds and that (after running sandbox with
the -Dl flags), 'mouse dump' shows mouse events.


Simon Glass (6):
  Add a few floating-point routines
  input: Add mouse support
  sandbox: sdl: Add support for mouse input
  usb: Add a USB mouse driver
  input: Add a command to show mouse input
  sandbox: Enable the mouse
