[PATCH 00/10] ARM: pxa: use software nodes/properties for GPIOs

This series converts legacy pxa boards (spitz, gumstix) to use software
nodes/properties to describe various GPIOs instead of relying on GPIO
lookup tables. The benefit is that structure and behavior is closer to
DT-described GPIOs.

The very first patch ("ARM: spitz: fix GPIO assignment for backlight")
is actually a fix that IMO should be applied sooner rather than later,
the rest of patches are enhancements. The reason it is sent with the
rest of the series is that later changes contextually depend on it.

The last patch ("ARM: spitz: Use software nodes for the ADS7846
touchscreen") soft-depends on corresponding changes by Linus Walleij to
the ads7846 driver in input tree. It compiles without it, but the device
will not sync with display refreshes. I have created an immutable branch
(branched from v6.9) at:

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git ib/ads7846-hsync

in case you wish to pull it in.

Regretfully it was only compiled as I do not have access to the relevant
hardware.
