2008-04-17[POWERPC] 83xx: mpc8315 - fix USB UTMI Host setupAnton Vorontsov
Currently USB Host isn't functional on the MPC8315E boards, for two reasons as described below. MPC8315 Reference Manual says: "The USB DR unit must have the same clock ratio as the encryption core unit, unless one of them has its clock disabled." The encryption core also drives I2C clock, so it is enabled and is equal to 01. That means USBDRCM should be 01 here. Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN clock from the 24.00MHz oscillator, which means we must adjust REFSEL bits as well. p.s. Idially we should rework whole 83xx/usb.c code, in two steps: 1. Move SCCR code to the U-Boot; 2. Implement fsl,usb-clock property in the device tree, so usb.c could decide what clock exactly to use on per-board basis. Though, today we're not in a hurry since there is just one 8315e board out there. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-12-20[POWERPC] pci32: Add flags modifying the PCI code behaviourBenjamin Herrenschmidt
This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all. This also adds the flag x86 already has to avoid ISA alignment on bridges that don't have ISA forwarding enabled (no legacy devices on the top level bus) and sets it for PowerMacs.

currently the board-level PHY reset code for the mpc832x MDS messes with reset configuration words source settings which is plain wrong (it looks like this board code was cut-n-pasted from the mpc8360 mds code, which has the PHY reset bits in a different BCSR); this patch points the PHY reset code to the proper mpc832x mds PHY reset bits in the BCSR.

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>

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.

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

2007-06-29[POWERPC] move 82xx/83xx/86xx Kconfig options to platform selectionArnd 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.
