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.

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.

This fixes the build with PCI disabled, we do want the
generic DMA facilities and interfaces even when just SBUS
is enabled.

The idea is to convert all of the PCI controller drivers into
genuine OF drivers, then we can get rid of this terrible probing
table and infrastructure in arch/sparc64/kernel/pci.c

These have no dependencies on the EBUS probing layer, the clients
setup the registers and all of those details.  The EBUS DMA layer
just programs and manages the DMA controller found in 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 thing was a mess, who wrote this junk? :)

Luckily we'll soon have nice generic I2C layer drivers for this PCF
based I2C stuff on sparc64.

The config stuff was already in drivers/watchdog/Kconfig
Signed-off-by: David S. Miller <davem@davemloft.net>

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 :-)

As we convert the various by-hand sparc64 RTC drivers to use the
generic RTC framework and drivers, we need to keep the NTP
set_rtc_mmss() support via update_persistent_clock() working.

In the end, after all the RTC device cases are converted, this
local set_rtc_mmss() function will be deleted.
