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>
2008-08-29sparc64: Use generic starfire RTC driver.David S. Miller
Also, delete the mini RTC driver, no longer used. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-29sparc: asm/mostek.h is now 32-bit onlyDavid S. Miller
No need for the 64-bit header version any more. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc64: Convert Mostek rtc to use generic RTC layer driver.David S. Miller

2008-08-29sparc64: Check for RTC class device in update_persistent_clock().David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc64: Select RTC_CLASSDavid S. Miller

No longer used. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Kill now spurious includes of sbus.hDavid S. Miller
In order to make this week I also had to add an include of linux/dma-mapping.h to asm/pci_32.h because drivers/pci/pci.c really depends upon getting this header somehow. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Kill iounit_map_dma_*().David S. Miller
Unused. Signed-off-by: David S. Miller <davem@davemloft.net>

No longer used. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Remove generic SBUS probing layer.David S. Miller
The individual SBUS IOMMU arch code now sets the IOMMU information directly into the OF device objects. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Add OF archdata propagation helper.David S. Miller
Add a helper function that, given a bus of_device node, propagates all iommu, stc, and host_controller values down to the child nodes. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Kill sbus_arch_preinit().David S. Miller
32-bit sparc just needed it to register the ioport procfs bits, do this via an arch_initcall() instead. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Kill sbus_is_slave().David S. Miller
Unused. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-29sparc: Convert remaining sbus_ioremap() and sbus_iounmap() users.David S. Miller
Use of_ioremap() and of_iounmap() instead. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Remove dinky old-style SBUS probing facilities.David S. Miller
No drivers or code uses this stuff any more, every driver has been converted over to OF device probing. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Remove SBUS layer resource and irq handling.David S. Miller
All the drivers use OF device objects now for this information. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Kill SBUS layer IRQ hooks.David S. Miller
IRQs are obtained by drivers from the of_device struct. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-29sparc32: Make mmu_map_dma_area and mmu_unmap_dma_area take a device pointer.David S. Miller
This lets us kill this "map it in every IOMMU" crazy code, and also some of the final references to sbus_root. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Kill mmu_translate_dvma and implementations.David S. Miller
No longer used. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Kill mmu_translate_dvma() usage.David S. Miller
Just simply use virt_to_page() on the provided virtual address pointer. Kill #if 0'd code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc64: Convert SBUS floppy probing to use OF device objects.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Move SBUS DMA attribute interfaces out of asm/sbus.hDavid S. Miller
This is in preparation for the subsequent asm/sbus.h removal. Also, make these routines take a "struct device" or no arguments, as appropriate. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Convert all SBUS drivers to dma_*() interfaces.David S. Miller
And all the SBUS dma interfaces are deleted. A private implementation remains inside of the 32-bit sparc port which exists only for the sake of the implementation of dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Implement more generic dma_*() interfaces.David S. Miller
These dispatch to either PCI or SBUS routines based upon the device bus type. This will allow us to let SBUS drivers call these routines. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Make mmu_{get,release}_*() take a struct device pointer.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Make SBUS DMA interfaces take struct device.David S. Miller
This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc32: Make IOMMU and IO-UNIT init work with device nodes.David S. Miller
And stick the iommu archdata pointer into the generic OF device tree of_device struct as well. We still have to pass the sbus_bus object down into the routines so that the SBUS bus objects get the iommu cookies set properly. After drivers get converted to being pure OF drivers, that can go away. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Kill SBUS DVMA layer.David S. Miller
This thing was completely pointless. Just find the OF device in the parent of drivers that want to program this device, and map the DMA regs inside such drivers too. This also moves the dummy claim_dma_lock() and release_dma_lock() implementation to floppy_32.h, which makes it handle this issue just like floppy_64.h does. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Kill videopix SBUS driver.David S. Miller
This has been marked BROKEN for a long time and it's more likely to get rewritten from scratch than to be fixed up and made usable. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-29sparc: Delete bare sbus char bpp driver, obsoleted by parport_sunbppDavid S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-25sparc64: Fix irq_of_parse_and_map() and irq_dispose_mapping().David S. Miller
Stephen Rothwell noticed that I committed an earlier version of the patch that didn't have two things fixed: 1) irq_of_parse_and_map() should return "unsigned int" not "int" and it should return zero for "no irq" 2) irq_dispose_mapping() should be an inline function, not a macro, for type checking With feedback and suggestions from Anton Vorontsov. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-25sparc64: Use the cond_syscall()s in kernel/sys_ni.c instead of home-grown copy.David S. Miller
This also allows arch/sparc64/kernel/pci.c to be properly CONFIG_PCI conditional compiled in the Makefile. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-25sparc64: Add JBUS UltraSPARC-IIIi support to memory controller driver.David S. Miller

Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-24sparc64: Add generic interface for registering a dimm printing handler.David S. Miller
The way to do this varies by platform type and the exact memory controller the cpu uses. For Spitfire cpus we currently just use prom_getunumber() and hope that works. For Cheetah cpus we have a memory controller driver that can compute this information. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-24sparc64: Use consistent chmc_ prefix in variables, types, and functions.David S. Miller

2008-08-24sparc64: Kill duplicated sys_pause() implementation.David S. Miller
sys32_pause() is identical to the generically provided sys_pause() in kernel/signal.c Noticed by Christoph Hellwig. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-24sparc64: Split syscall_trace() into two functions.David S. Miller
Christoph Hellwig noticed that having both entry and exit logic in one function no longer makes sense, and having seperate ones simplifies things a lot. Signed-off-by: David S. Miller <davem@davemloft.net>
