Pull devicetree updates from Rob Herring:

 - Rewrite of the unflattening code to avoid recursion and lessen the
   stack usage.

 - Rewrite of the phandle args parsing code to get rid of the fixed args
   size.  This is needed for IOMMU code.

 - Sync to latest dtc which adds more dts style checking.  These
   warnings are enabled with "W=1" compiles.

 - Tegra documentation updates related to the above warnings.

 - A bunch of spelling and other doc fixes.

 - Various vendor prefix additions.

Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices.

Rename sub-nodes to avoid new dtc unit address warnings when copied.

While at it, adopt the dashes convention for the node name.

In Cygnus SOC touch screen controller registers are shared with ADC and
flex timer. Using readl/writel could lead to race condition. So touch
screen driver is enhanced to support register access using syscon framework
API's to take care of mutually exclusive access.
