    Pull MIPS updates from Ralf Baechle:
    "This is the main pull request for MIPS for Linux 4.1. Most
    noteworthy:

    - Add more Octeon-optimized crypto functions
    - Octeon crypto preemption and locking fixes
    - Little endian support for Octeon
    - Use correct CSR to soft reset Octeons
    - Support LEDs on the Octeon-based DSR-1000N
    - Fix PCI interrupt mapping for the Octeon-based DSR-1000N
    - Mark prom_free_prom_memory() as __init for a number of systems
    - Support for Imagination's Pistachio SOC. This includes arch and
    CLK bits. I'd like to merge pinctrl bits later
    - Improve parallelism of csum_partial for certain pipelines
    - Organize DTB files in subdirs like other architectures
    - Implement read_sched_clock for all MIPS platforms other than
    Octeon
    - Massive series of 38 fixes and cleanups for the FPU emulator /
    kernel
    - Further FPU remulator work to support new features. This sits on a
    separate branch which also has been pulled into the 4.1 KVM branch
    - Clean up and fixes for the SEAD3 eval board; remove unused file
    - Various updates for Netlogic platforms
    - A number of small updates for Loongson 3 platforms
    - Increase the memory limit for ATH79 platforms to 256MB
    - A fair number of fixes and updates for BCM47xx platforms
    - Finish the implementation of XPA support
    - MIPS FDC support. No, not floppy controller but Fast Debug Channel :)
    - Detect the R16000 used in SGI legacy platforms
    - Fix Kconfig dependencies for the SSB bus support"

  • 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.

    Pull GPIO changes from Linus Walleij:
    "This is the bulk of GPIO changes for the v3.18 development cycle:

    - Increase the default ARCH_NR_GPIO from 256 to 512. This was done
    to avoid having a custom header for the x86
    architecture - GPIO is custom and complicated enough as it is
    already! We want to move to a radix to store the descriptors going
    forward, and finally get rid of this fixed array size altogether.

    - Endgame patching of the gpio_remove() semantics initiated by
    Abdoulaye Berthe. It is not accepted by the system that the
    removal of a GPIO chip fails during eg reboot or shutdown, and
    therefore the return value has now painfully been refactored away.
    For special cases like GPIO expanders on a hot-pluggable bus like
    USB, we may later add some gpiochip_try_remove() call, but for the
    cases we have now, return values are moot.

    - Some incremental refactoring of the gpiolib core and ACPI GPIO
    library for more descriptor usage.

    - Refactor the chained IRQ handler set-up method to handle also
    threaded, nested interrupts and set up the parent IRQ correctly.
    Switch STMPE and TC3589x drivers to use this registration method.

    - Add a .irq_not_threaded flag to the struct gpio_chip, so that also
    GPIO expanders that block but are still not using threaded IRQ
    handlers.

    - New drivers for the ARM64 X-Gene SoC GPIO controller.

    - The syscon GPIO driver has been improved to handle the "DSP GPIO"
    found on the TI Keystone 2 SoC:s.

    - ADNP driver switched to use gpiolib irqchip helpers.

    - Refactor the DWAPB driver to support being instantiated from and
    MFD cell (platform device).

    - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,
    Xilinx and Crystalcove drivers.

    - Various minor fixes"
