2009-01-07USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]Vitaly Bordug
A published errata for ppc440epx states, that when running Linux with both EHCI and OHCI modules loaded, the EHCI module experiences a fatal error when a high-speed device is connected to the USB2.0, and functions normally if OHCI module is not loaded. There used to be recommendation to use only hi-speed or full-speed devices with specific conditions, when respective module was unloaded. Later, it was observed that ohci suspend is enough to keep things going, and it was turned into workaround, as explained below. Quote from original descriprion: The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB 2.0 Host controllers, each EHCI controller has one or more companion controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will contain one or more ports. For each port, only one of the controllers is connected at any one time. In the 440EPx, there is only one OHCI companion controller, and only one USB 2.0 Host port. All ports on an USB 2.0 controller default to the companion controller. If you load only an ohci driver, it will have control of the ports and any deviceplugged in will operate, although high speed devices will be forced to operate at full speed. When an ehci driver is loaded, it explicitly takes control of the ports. If there is a device connected, and / or every time there is a new device connected, the ehci driver determines if the device is high speed or not. If it is high speed, the driver retains control of the port. If it is not, the driver explicitly gives the companion controller control of the port. The is a software workaround that uses Initial version of the software workaround was posted to linux-usb-devel: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html and later available from amcc.com: http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2 The patch below is generally based on the latter, but reworked to powerpc/of_device USB drivers, and uses a few devicetree inquiries to get rid of (some) hardcoded defines.

2008-07-09ibm_newemac: Parameterize EMAC Multicast Match HandlingGrant Erickson
Various instances of the EMAC core have varying: 1) number of address match slots, 2) width of the registers for handling address match slots, 3) number of registers for handling address match slots and 4) base offset for those registers. As the driver stands today, it assumes that all EMACs have 4 IAHT and GAHT 32-bit registers, starting at offset 0x30 from the register base, with only 16-bits of each used for a total of 64 match slots. The 405EX(r) and 460EX now use the EMAC4SYNC core rather than the EMAC4 core. This core has 8 IAHT and GAHT registers, starting at offset 0x80 from the register base, with ALL 32-bits of each used for a total of 256 match slots. This adds a new compatible device tree entry "emac4sync" and a new, related feature flag "EMAC_FTR_EMAC4SYNC" along with a series of macros and inlines which supply the appropriate parameterized value based on the presence or absence of the EMAC4SYNC feature. The code has further been reworked where appropriate to use those macros and inlines. In addition, the register size passed to ioremap is now taken from the device tree: c4 for EMAC4SYNC cores 74 for EMAC4 cores 70 for EMAC cores rather than sizeof (emac_regs). Finally, the device trees have been updated with the appropriate compatible entries and resource sizes. This has been tested on an AMCC Haleakala board such that: 1) inbound ICMP requests to 'haleakala.local' via MDNS from both Mac OS X 10.4.11 and Ubuntu 8.04 systems as well as 2) outbound ICMP requests from 'haleakala.local' to those same systems in the '.local' domain via MDNS now work.

2008-05-29[POWERPC] Convert remaining dts-v0 files to v1David Gibson
At the moment we have a mixture of left-over version 0 and new-format version 1 files in arch/powerpc/boot/dts. This is potentially confusing to people new to the dts format attempting to figure it out. So, this patch converts all the as-yet unconverted dts v0 files and converts them to v1. They're mechanically-converted, and not hand tweaked so in some cases they're not 100% in keeping with usual v1 style, but the convertor program does have some heuristics so the discrepancies aren't too bad. I have checked that this patch produces no changes to the resulting dtb binaries.

This patch is fixes the sequoia.dts device tree file to use the values defined in the 440Epx data sheet from AMCC. That fixes an issue where some devices, including graphics cards, would not initialize properly because the PCI resource space was not big enough.

2008-03-26[POWERPC] Start removing linux,network-index in favour of aliasesDavid Gibson
This patch alters the bootwrapper for a number of machines (roubhly all 4xx based cuboot or treeboot platforms) to use aliases instead of the linux,network-index hack to work out which MAC address to attach to which ethernet device node. The now obsolete linux,network-index properties are removed from the corresponding device trees. This won't break backwards compatiblity, because in cases where this fixup code is relevant, the device tree is part of the kernel image. The references to linux,network-index are removed from booting-without-of.txt. Not only is it now deprecated, but as a hack applicable only when the device tree blob and fixup code were in the same image, this property never belonged in booting-without-of.txt which describes the interface between the kernel and firmware or bootloaders which produce a device tree. By the time the device tree reaches the kernel, all the MAC addresses must be fully filled in.

2007-12-23[POWERPC] 4xx: Rename CPU nodes to avoid dtc incompatibilityJosh Boyer
Recent DTC versions disallow certain special characters in full paths without being quoted with {}. That however breaks compatibility with older DTC versions. Work around this by renaming the CPU nodes for the 4xx files to a generic node name, and specify the processor type in the model property of the CPU node.
