  • 69b5f4da2   bcma: add support for population subnodes also when build as module ... Browse Code »

    of_default_bus_match_table was not exported earlier, so it could only
    be accessed by code compiled into the kernel. A new function
    of_platform_default_populate() was added which uses
    of_default_bus_match_table and this function is also exported. This way
    it is possible to create a bus with the content of
    of_default_bus_match_table and we can remove the hacks from bcma.

  • 53cd2fdb0   bcma: fix access to host_pdev for PCIe devices ... Browse Code »

    bus->host_pdev is part of a union so bus->host_pdev != NULL is probably
    also true for PCIe devices, because there it accesses bus->host_pci. If
    we access the dev member at the offset defined in struct
    platform_device in struct pci_dev instead we probably get something
    else.

    This patch adds a new function which returns the host dev struct and
    NULL if we do not have a host dev. When this gets registered on MIPS
    brcm47xx we do not have a host dev in some situations.
    This function could also be used in other places.

    This problem was introduced in this commit:

    This extension of BCMA_DRIVER_PCI has no reason to depend on
    BCMA_HOST_PCI. User may just want to have PCI device attached to SoC
    registered without enabling any extra client mode code.
    This can be useful when having non-bcma PCI device attached or when
    using other PCI driver.

  • 138173d4e   MIPS: BCM47xx: Move NVRAM header to the include/linux/. ... Browse Code »

    There are two reasons for having this header in the common place:
    1) Simplifying drivers that read NVRAM entries. We will be able to
    safely call bcm47xx_nvram_* functions without #ifdef-s.
    2) Getting NVRAM driver out of MIPS arch code. This is needed to support
    BCM5301X arch which also requires this NVRAM driver. Patch for that
    will follow once we get is reviewed.

  • 1ca2760fb   bcma: prepare Kconfig symbol for PCI driver ... Browse Code »

    Driver for PCIe core requires PCI to be enabled, however we shouldn't
    require it for the whole bus. Someone may be not interested in extra
    PCI devices and what's more there are SoCs without any PCI at all (like
    BCM5356C0, BCM5357*, BCM47186B0). For more details see Kconfig "help".
    Please note this patch doesn't allow disabling PCI drivers yet, as it
    requires more work on calls to bcma_core_pci_* functions.
