* [POWERPC] get_property cleanupsStephen Rothwell2007-04-302-8/+9
| | | | | | | Just another pass through arch/powerpc for old usages. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Generic check_legacy_ioportOlaf Hering2007-04-271-7/+0
| | | | | | | | | | | check_legacy_ioport makes only sense on PREP, CHRP and pSeries. They may have an isa node with PS/2, parport, floppy and serial ports. Remove the check_legacy_ioport call from ppc_md, it's not needed anymore. Hardware capabilities come from the device-tree.

| | | | | | | | | arch/powerpc/platforms/pasemi/gpio_mdio.c really depends on CONFIG_PHYLIB. Add a config option for it, allow for it to be disabled if needed and fix the dependency. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] pasemi: Allow 8KB config space for I/O bridgeOlof Johansson2007-04-241-3/+13
| | | | | | | | | | Device 0 function 0 on the root bus is really a two-function bus agent, but only the first function is visible. Because of this, we need to allow config accesses into the second range. Modify the check for valid offsets accordingly.

* [POWERPC] pasemi: Configure DMA controller interruptsOlof Johansson2007-02-073-0/+15
| | | | | | | | | | | | | The DMA controller on PWRficient is somewhat special -- has a PCI header so it looks like it's on the root PCI (-Express) root bus, but it uses more than the default number of interrupts (and they are hardwired). We need to wire up all interrupts for the DMA controller. The generic IRQ code will only map the primary interrupt from the PCI header (128), so add 129->211 by hand.

* [POWERPC] pasemi: SMP timebase syncOlof Johansson2007-02-071-2/+25

* [POWERPC] MPIC: support more than 256 sourcesOlof Johansson2007-02-071-2/+3
| | | | | | | | | | | | | Allow more than the default 256 MPIC sources. Allocates a new flag (MPIC_LARGE_VECTORS) to be used by platform code when instantiating the mpic. I picked 11 bits worth right now since it would cover the number of sources on any hardware I have seen. It can always be increased later if needed.

* [POWERPC] Fix unbalanced uses of of_node_putNathan Lynch2007-01-091-1/+0
| | | | | | | | | | The (maple|pasemi)_init_IRQ functions call of_node_put(root) once more than they should, causing the refcount of the root node to underflow, which triggers the WARN_ON in kref_get.

* [POWERPC] Refactor 64 bits DMA operationsBenjamin Herrenschmidt2006-12-041-12/+4
| | | | | | | | | | | | | | | | | This patch completely refactors DMA operations for 64 bits powerpc. 32 bits is untouched for now. We use the new dev_archdata structure to add the dma operations pointer and associated data to struct device. While at it, we also add the OF node pointer and numa node. In the future, we might want to look into merging that with pci_dn as well. The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced by a set of generic iommu and direct DMA ops (non PCI specific) that can be used by bus types. The toplevel implementation is now inline.

* [POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt2006-12-043-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

* [POWERPC] powerpc: PA Semi PWRficient platform supportOlof Johansson2006-09-135-0/+424
Base patch for PA6T and PA6T-1682M. This introduces the arch/powerpc/platform/pasemi directory, together with basic implementations for various setup.
