From: Stephen Boyd <swboyd@xxxxxxxxxxxx> Add support to the hammer driver to parse vivaldi keyboard layouts and expose them to userspace. This allows hammer devices to use vivaldi function row keys while also supporting the other features this driver supports, like the CBAS (chrome base attached switch) and a keyboard backlight.
