  • 2bedea8f2   bcma: make bcma_core_pci_{up,down}() callable from atomic context ... Browse Code »

    This patch removes the bcma_core_pci_power_save() call from
    the bcma_core_pci_{up,down}() functions as it tries to schedule
    thus requiring to call them from non-atomic context. The function
    bcma_core_pci_power_save() is now exported so the calling module
    can explicitly use it in non-atomic context. This fixes the
    'scheduling while atomic' issue reported by Tod Jackson and
    Joe Perches.

  • 0f58a01dd   Drivers: bcma: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, and __devexit
    from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

    pc could be null if hosttype != BCMA_HOSTTYPE_PCI.
    If we are on a device without a pci core this function is called with
    pc = null by b43 and brcmsmac. If the host type is PCI we have a pci
    core as well and pc can not be null.

  • ecd177c21   bcma: add SOC bus ... Browse Code »

    This patch adds support for using bcma on a Broadcom SoC as the system
    bus. An SoC like the bcm4716 could register this bus and use it to
    searches for the bcma cores and register the devices on this bus.

    BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC
    is a better name.

  • 517f43e5a   bcma: add functions to scan cores needed on SoCs ... Browse Code »

    The chip common and mips core have to be setup early in the boot
    process to get the cpu clock.
    bcma_bus_early_register() gets pointers to some space to store the core
    data and searches for the chip common and mips core and initializes
    chip common. After that was done and the kernel is out of early boot we
    just have to run bcma_bus_register() and it will search for the other
    cores, initialize and register them.
    The cores are getting the same numbers as before.

  • 440ca98fe   bcma: clean exports of functions ... Browse Code »

    Function managing IRQs is needed for external drivers like b43.
    On the other side we do not expect writing any hosts drivers outside of
    bcma, so this is safe to do not export functions related to this.

  • 8369ae33b   bcma: add Broadcom specific AMBA bus driver ... Browse Code »

    Broadcom has released cards based on a new AMBA-based bus type. From a
    programming point of view, this new bus type differs from AMBA and does
    not use AMBA common registers. It also differs enough from SSB. We
    decided that a new bus driver is needed to keep the code clean.

    In its current form, the driver detects devices present on the bus and
    registers them in the system. It allows registering BCMA drivers for
    specified bus devices and provides them basic operations. The bus driver
    itself includes two important bus managing drivers: ChipCommon core
    driver and PCI(c) core driver. They are early used to allow correct
    initialization.

    Currently code is limited to supporting buses on PCI(e) devices, however
    the driver is designed to be used also on other hosts. The host
    abstraction layer is implemented and already used for PCI(e).

    Support for PCI(e) hosts is working and seems to be stable (access to
    80211 core was tested successfully on a few devices). We can still
    optimize it by using some fixed windows, but this can be done later
    without affecting any external code. Windows are just ranges in MMIO
    used for accessing cores on the bus.
