2007-10-08[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascadingAnton Vorontsov
set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.

2007-10-08[POWERPC] Use for_each_ matching routinues for pci PHBsKumar Gala
On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

mpc834x USB-MPH configuration got broken by commit 6f442560021aecf08658e26ed9a37e6928ef0fa1. The selection bits in SICRL should be cleared rather than set to configure the USB MUXes for the MPH. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-14[POWERPC] MPC832x_RDB: Update dts to use SPI1 in QE, register mmc_spi stubAnton Vorontsov
Enabled using SPI controller on the MPC832x RDB board. We currently use a modalias of "spidev" as a place holder (replace with "mmc_spie") until the mmc_spi driver support is merged in. This gets us the ability to test SPI until then. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Remove includes of files that existed in arch/ppc that we dont need in arch/powerpc anymore. The following includes were removed: <asm/amigappc.h> <asm/bootinfo.h> <asm/ppcboot.h> <asm/ppc_sys.h> <asm/residual.h> <asm/m8260_pci.h> This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be needed and thus removed.

2007-08-10[POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms ↵Kim Phillips
with QE UEC" This reverts commit 3baee955953957be5496cd28e9c544d9db214262. That commit was a mistake from the start; I added mdio type to the bus scan list early on in my ucc_geth migrate to phylib development, which is just pure wrong (the ucc_geth_mii driver creates the mii bus and the PHY layer handles PHY enumeration without translation). This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb: Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()" which was basically trying to hide a symptom of the original mistake this revert fixes.

2007-06-29[POWERPC] Removed remnants of bus_offsetKumar Gala
Removed the remants of bus_offset and use self_busno in the mv64x60 case and use pci_assign_all_buses on 83xx/85xx. 83xx/85xx have multiple PHBs and the firmwares on these devices tend not to handle topologies with P2P bridges well so we let Linux just reassign the bus numbers to match. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Remove hack to determine the 2nd PHBs bus numberKumar Gala
Now that we have the pci_controller in the exclude function we can easy figure out if the bus number is the PHB or not. The old style of using a variable setup at init time was actually broken and would only work in specific cases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala
There are times that we need to know which controller we are on to decide how to exclude devices properly. We now pass the pci_controller that we are going to use down to the pci_exclude_device function. This will greatly simplify being able to exclude the PHBs in multiple controller setups.

2007-06-29[POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala
The Freescale and Marvell PCI controllers dont require explicit setting for type 1 config cycles. They handle producing them by implicitly looking at the bus, devfn. The TSI108 and 52xx don't use the generic PCI indirect code and thus don't bother with set_cfg_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] kill isa_{io,mem}_base definitions for !PCIArnd Bergmann

2007-06-29[POWERPC] rename add_bridge to avoid namespace clashesArnd Bergmann

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar to those in the 32 bit general-purpose processors, so it makes sense to treat them as the same CPU family. Choosing between the embedded platforms and the multiplatform code is now done in the platform menu, but functionally everything stays the same. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2007-01-26[POWERPC] 83xx: Don't call ioremap in the reset functionKumar Gala
It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-01-22[POWERPC] Fix OF node refcnt underflow in 836x and 832x platform codeLi Yang
Incorrect use of of_find_node_by_name() causes of_node_put() on a node which has already been put.

2006-12-04[POWERPC] Remove ppc_md.pci_map_irq & ppc_swizzle for ARCH=powerpcBenjamin Herrenschmidt
These were inherited from ARCH=ppc, but are not needed since parsing of interrupts should be done via the of_* functions (who can do swizzling). If we ever need to do non-standard swizzling on bridges without a device-node, then we might add back a slightly different version of ppc_md.pci_swizzle but for now, that is not the case. I removed the couple of calls for these in 83xx. If that breaks something, then there is a problem with the device-tree on these.

2006-12-04[POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt
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.
