2008-09-03sparc32: use RTC subsystemDavid S. Miller
Use rtc subsystem for sparc32 architecture. Actually, only one driver is needed: m48t59 as it supports the most common clocks on sparc32 machines: m48t08 and m48t02. [ Add proper RTC layer calls to set_rtc_mmss() -DaveM ] Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-03rtc-m48t59: allow externally mapped ioaddrKrzysztof Helt
Add support for externally mapped ioaddr. This is required on sparc32 as the ioaddr must be mapped with of_ioremap(). Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-03rtc-m48t59: add support for M48T02 and M48T59 chipsKrzysztof Helt
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.

2008-09-03rtc-m48t59: reduce structure m48t59_privateKrzysztof Helt
Remove element size from the structure m48t59_private as it is used as local variable for storing temporary value.

2008-09-03sparc: Fix handling of LANCE and ESP parent nodes in of_device.cDavid S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>

This mirrors the of_device_id[] changes done in fd098316ef533e8441576f020ead4beab93154ce ("sparc: Annotate of_device_id arrays with const or __initdata.") Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-31sparc64: Clean up CPU chip type probing code.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-31sparc: remove CONFIG_SUN4Adrian Bunk
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.

2008-08-31sparc64: Rewrite central driver.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-30sparc: Stop setting NO_DMA.David S. Miller
This fixes the build with PCI disabled, we do want the generic DMA facilities and interfaces even when just SBUS is enabled. Based upon a build failure report by Robert Reif. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-30sparc64: Convert SCHIZO PCI controller driver into a real driver.David S. Miller
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 Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-29sparc: Move EBUS DMA interfaces into seperate header file.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-29sparc64: Propagate PCI device archdata into OF device tree for EBUS.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29bbc_i2c: Convert to pure OF driver.David S. Miller

2008-08-29riowatchdog: Convert to pure OF driver.David S. Miller
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.
