[PATCH 0/3] add devicetree bindings for rtc-m48t86

Currently there are two users of rtc-m48t86 (mach-ep93xx/ts72xx.c and
mach-orion5x/ts78xx-setup.c) and both just use {read,write}b against
a memory mapped region.  As I am devicetree'ing the TS-7800, this
driver needs converting and thats what this patchset does.

The patch does the following:
 * remove platform specific ops hooks, moving ioremap'ing and
	everything into the driver
 * utilises named resources to indicate index/data ranges
 * moves the RTC detection routine from ts78xx-setup.c into rtc-m48t86.c
 * and, of course, enable devicetree hooks and include documentation

Awkward step, the first patch breaks both boards, the two following
patches fix them.  Happy to re-work this if folks give me a pointer
on how to do this in an acceptable way.

My vote is to break fast, fix fast, spend the time writing other code :)
