  14   Bindings for Broadcom's BCM63xx memory-mapped GPIO controllers.
  15
  16   These bindings can be used on any BCM63xx SoC. However, BCM6338 and BCM6345
  17   are the only ones which don't need a pinctrl driver.
  18
  19   BCM6338 have 8-bit data and dirout registers, where GPIO state can be read
  20   and/or written, and the direction changed from input to output.
  21   BCM6318, BCM6328, BCM6358, BCM6362, BCM6368 and BCM63268 have 32-bit data
  22   and dirout registers, where GPIO state can be read and/or written, and the
  23   direction changed from input to output.
