64151ad5b3 rtc-m48t59: allow externally mapped ioaddr
Add support for externally mapped ioaddr.  This is required on sparc32
as the ioaddr must be mapped with of_ioremap().

94fe7424a4 rtc-m48t59: add support for M48T02 and M48T59 chips
Add support for two compatible RTC:
- M48T08 which does not have alarm part,
- M48T08 which does not have alarm part and has
  only 2KB of NVRAM

These types covers all Mostek's RTC used in Sun UltraSparc workstations.

Tested on Sun Ultra60 with M48T59 RTC.

5280267c1d sparc: Fix handling of LANCE and ESP parent nodes in of_device.c
The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges'
property, but we should pass the translation up to the parent node so
that the SBUS level ranges get applied.

Based upon a bug report from Robert Reif.

ba4962d7a6 sparc64: Clean up CPU chip type probing code.
Three main things:

1) Make prober an arch initcall instead of using hard-coded invocation
   from paging_init()

2) Shrink table size, the fpu ident stuff was never used.

3) Use named struct initialized in table.

5110bd21b8 sparc: remove CONFIG_SUN4
While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.

And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

b69416b51b sparc64: Rewrite central driver.
This driver is now limited to just doing the basic clock board and FHC
chip initialization and registering the platform devices for the
per-board LEDs, which are driven by the new LEDS_STARFIRE driver.

The IRQ register handling is already confined purely to the device
tree code.

ae05f87ee2 sparc64: Propagate PCI device archdata into OF device tree for EBUS.
In order to convert EBUS drivers doing DMA into pure OF drivers,
we need the of_device->dev.archdata setup properly.

EBUS instances that can provide DMA for device nodes sit on PCI,
so detect and propagate the information there.

This also cleans up a lot of crud in this driver:

1) Don't touch the BBC regs, just leave the watchdog trigger
   behavior whatever the firmware programmed it to.

2) Use WATCHDOG_MINOR instead of hardcoded and not properly
   allocated RIOWD_MINOR.

Hey, I haven't touched it since I wrote it years ago :-)
