      tegra: Add tegra keyboard driver · 6642a681
      Rakesh Iyer authored
      Add support for internal matrix keyboard controller for Nvidia Tegra
      platforms. This driver uses the fdt decode function to obtain its key
      codes.
      
      Support for the Ctrl modifier is provided. The left and right ctrl keys are
      dealt with in the same way.
      
      This uses the new keyboard input library (drivers/input/input.c) to decode
      keys and handle most of the common input logic. The new key matrix library
      is also used to decode (row, column) key positions into key codes.
      
      The intent is to make this driver purely about dealing with the hardware.
      
      Key detection before the driver is loaded is supported. This key will be
      picked up when the keyboard driver is initialized.
      
      Modified by Bernie Thompson <bhthompson@chromium.org> and
      Simon Glass <sjg@chromium.org> for device tree, input layer, key matrix
      and various other things.
