[U-Boot] [PATCH 0/4] x86: support of pin-muxing from device tree

[Gabriel Huau]

This serie of patches adds the support of pin-muxing from the device tree through
different properties. I have put two example to enable the USB Host on the
minnowboard max.

The support of the call to 'setup_pch_gpios' is still supported and
only the minnowboard has been tested with the device tree implementation.

Because the GPIO and IO base register ares different, I have also defined
some proxy function to set the function/value and direction of the GPIO as
the GPIO register can override some registers in the IO.

Gabriel Huau (4):
  x86: baytrail: fix the GPIOBASE address
  x86: minnowmax: add GPIO banks in the device tree
  x86: gpio: add pinctrl support from the device tree
  x86: minnowmax: initialize the pin-muxing from device tree
