* sparc64: Check for RTC class device in update_persistent_clock().David S. Miller2008-08-291-0/+5
| | | | | | | | | | | 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>

* sparc: Kill now spurious includes of sbus.hDavid S. Miller2008-08-2914-14/+9
| | | | | | | | 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>

* sparc: Remove generic SBUS probing layer.David S. Miller2008-08-297-112/+108
| | | | | | | 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>
* sparc: Add OF archdata propagation helper.David S. Miller2008-08-293-0/+46
| | | | | | | 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>
* sparc: Kill sbus_arch_preinit().David S. Miller2008-08-292-14/+3
| | | | | | | 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>

* sparc: Remove dinky old-style SBUS probing facilities.David S. Miller2008-08-294-28/+0
| | | | | | | 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>
* sparc: Remove SBUS layer resource and irq handling.David S. Miller2008-08-294-62/+0
| | | | | | | All the drivers use OF device objects now for this information. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill SBUS layer IRQ hooks.David S. Miller2008-08-297-144/+0
| | | | | | IRQs are obtained by drivers from the of_device struct. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc32: Make mmu_map_dma_area and mmu_unmap_dma_area take a device pointer.David S. Miller2008-08-295-23/+19
| | | | | | | 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>
* sparc32: Kill mmu_translate_dvma and implementations.David S. Miller2008-08-294-34/+0

* sparc32: Kill mmu_translate_dvma() usage.David S. Miller2008-08-291-35/+1
| | | | | | | | 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>
* sparc64: Convert SBUS floppy probing to use OF device objects.David S. Miller2008-08-291-18/+27

* sparc: Move SBUS DMA attribute interfaces out of asm/sbus.hDavid S. Miller2008-08-296-12/+36
| | | | | | | | | 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>
* sparc: Convert all SBUS drivers to dma_*() interfaces.David S. Miller2008-08-294-96/+0
| | | | | | | | | 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>
* sparc32: Implement more generic dma_*() interfaces.David S. Miller2008-08-295-6/+298
| | | | | | | | | 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>
* sparc32: Make mmu_{get,release}_*() take a struct device pointer.David S. Miller2008-08-294-53/+47
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Make SBUS DMA interfaces take struct device.David S. Miller2008-08-295-73/+42
| | | | | | | This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make IOMMU and IO-UNIT init work with device nodes.David S. Miller2008-08-295-40/+45
| | | | | | | | | | | 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>
* sparc: Kill SBUS DVMA layer.David S. Miller2008-08-296-500/+147
| | | | | | | | | | | | | 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>
* sparc: Kill videopix SBUS driver.David S. Miller2008-08-292-59/+0
| | | | | | | 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>
* sparc: Delete bare sbus char bpp driver, obsoleted by parport_sunbppDavid S. Miller2008-08-294-76/+0
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix irq_of_parse_and_map() and irq_dispose_mapping().David S. Miller2008-08-253-6/+8
| | | | | | | | | | | | | | | 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>
* sparc64: Use the cond_syscall()s in kernel/sys_ni.c instead of home-grown copy.David S. Miller2008-08-252-20/+2
| | | | | | | 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>
* sparc64: Add JBUS UltraSPARC-IIIi support to memory controller driver.David S. Miller2008-08-251-83/+453

* sparc64: Add generic interface for registering a dimm printing handler.David S. Miller2008-08-243-13/+79
| | | | | | | | | | | | | 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>
* sparc64: Use consistent chmc_ prefix in variables, types, and functions.David S. Miller2008-08-241-117/+120

* sparc64: Convert UltraSPARC-III memory controller driver to OF driver probing.David S. Miller2008-08-241-41/+78

* sparc64: Kill duplicated sys_pause() implementation.David S. Miller2008-08-242-9/+1
| | | | | | | | | 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>
* sparc64: Split syscall_trace() into two functions.David S. Miller2008-08-244-32/+30
| | | | | | | | 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>
* sparc: Add GPIO layer support.David S. Miller2008-08-243-0/+48
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Implement irq_of_parse_and_map() and irq_dispose_mapping().David S. Miller2008-08-243-0/+30
| | | | | | | This allows more OF layer code to be shared between powerpc and sparc. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Add mutex for set property calls.David S. Miller2008-08-243-0/+14
| | | | | | | | | | | | | On some platforms, the I2C controller is shared between the OS and OBP. OBP uses this I2C controller to access the EEPROM, and thus is programmed when the kernel calls prom_setprop(). Wrap such calls with the new of_set_property_mutex. Relevant I2C bus drivers can grab this mutex around top-level I2C operations to provide the proper protection. Signed-off-by: David S. Miller <davem@davemloft.net>
