    "Driver updates for ARM SoCs, including a couple of newly added
    drivers:

    - The Qualcomm external bus interface 2 (EBI2), used in some of their
    mobile phone chips for connecting flash memory, LCD displays or
    other peripherals

    - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for
    the EFUSE based on that firmware interface.

    - Perf support for the AppliedMicro X-Gene performance monitor unit

    - Reset driver for STMicroelectronics STM32

    - Reset driver for SocioNext UniPhier SoCs

    Aside from these, there are minor updates to SoC-specific bus,
    clocksource, firmware, pinctrl, reset, rtc and pmic drivers"

  • 23540d6e2   memory: omap-gpmc: allow probe of child nodes to fail ... Browse Code »

    A recent commit (inadvertently?) changed how failed probe of a gpmc
    child node was handled. Instead of proceeding with setting up any other
    children as before, a single error now aborts the whole process.

    This change broke networking on some Overo boards due to probe failing
    for an unrelated nand node. This second issue should obviously be
    fixed, but let's restore the old behaviour of allowing child-node
    probe to fail to avoid further similar breakage on other systems.

    for WAITPINs")

    Mediatek SMI has two generations of HW architecture, mt8173 uses the
    second generation of SMI HW while mt2701 uses the first generation
    HW of SMI.

    There's slight differences between the two generations, for generation 2,
    the register which control the iommu port access PA or IOVA is at each
    larb's register base. But for generation 1, the register is at smi ao
    base(smi always on register base).
    Besides that, the smi async clock should be prepared and enabled for SMI
    generation 1 HW to transform the smi clock into emi clock domain, but is
    not needed for SMI generation 2.

    This patch add SMI driver for mt2701 which use generation 1 SMI HW.

    for_each_child_of_node() performs an of_node_get() on each iteration, so
    to break out of the loop an of_node_put() is required.

    Found using Coccinelle. The semantic patch used for this is as follows:

    //
    @@
    expression e;
    local idexpression n;
    @@

    for_each_child_of_node(..., n) {
    ... when != of_node_put(n)
    when != e = n
    (
    return n;
    |
    + of_node_put(n);
    ? return ...;
    )
    ...
    }

  • 6a4ec4cd0   memory: add Atmel EBI (External Bus Interface) driver ... Browse Code »

    The EBI (External Bus Interface) is used to access external peripherals
    (NOR, SRAM, NAND, and other specific devices like ethernet controllers).
    Each device is assigned a CS line and an address range and can have its
    own configuration (timings, access mode, bus width, ...).
    This driver provides a generic DT binding to configure a device according
    to its requirements.
    For specific device controllers (like the NAND one) the SMC timings
    should be configured by the controller driver through the matrix and
    smc syscon regmaps.

    Pull MTD updates from Brian Norris:
    "First cycle with Boris as NAND maintainer! Many (most) bullets stolen
    from him.

    Generic:
    - Migrated NAND LED trigger to be a generic MTD trigger

    NAND:
    - Introduction of the "ECC algorithm" concept, to avoid overloading
    the ECC mode field too much more
    - Replaced the nand_ecclayout infrastructure with something a little
    more flexible (finally!) and future proof
    - Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some
    of this into their own tree as well
    - Prepare the sunxi NAND driver to receive DMA support
    - Handle bitflips in erased pages on GPMI revisions that do not
    support this in hardware.

    SPI NOR:
    - Start using the spi_flash_read() API for SPI drivers that support
    it (i.e., SPI drivers with special memory-mapped flash modes)

    And other small scattered improvments"

    "Here's the main drm pull request for 4.7, it's been a busy one, and
    I've been a bit more distracted in real life this merge window. Lots
    more ARM drivers, not sure if it'll ever end. I think I've at least
    one more coming the next merge window.

    But changes are all over the place, support for AMD Polaris GPUs is in
    here, some missing GM108 support for nouveau (found in some Lenovos),
    a bunch of MST and skylake fixes.
