  • 279d0ab35   wandboard: Remove repeated PMIC string ... Browse Code »

    After the conversion to DM_PMIC the following output is seen:

    PMIC: PMIC: PFUZE100 ID=0x10

    Remove the unnecessary PMIC string from the board file to
    avoid the repetead string.

  • 21f77b77a   wandboard: Fix the DM_PMIC conversion ... Browse Code »

    Commit ec837c82d709 ("imx6: wandboard: convert to DM_PMIC")
    caused the following pmic_get() error:

    CPU: Freescale i.MX6QP rev1.0 at 792 MHz
    Reset cause: POR
    DRAM: 2 GiB
    PMIC: pmic_get() ret -19
    ...

    and since the PMIC presence is used to determine the board D1 revision,
    the following error is seen when booting a board rev D1:

    WARNING: Could not determine dtb to use

    and the kernel does not boot at all.

    Fix the regression by passing "pfuze100@8" as the correct parameter
    to the pmic_get() function in the DM case.

  • d1337210d   wandboard: Don't use I2C speed Kconfig settings with DM_I2C ... Browse Code »

    When using DM_I2C the speed value supplied to setup_i2c() is not used,
    so this code required CONFIG_SYS_MXC_I2C[12]_SPEED to be defined to
    compile, but did not actually use them.

    Change this so we no longer need to define an unused macro to compile in
    DM_I2C mode. Also make it more clear that they do not control the bus
    speed. Otherwise it is quite easy to mistakenly believe they are used
    to set the bus speed.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 066d97c73   wandboard: Add support for the latest revd1 revision ... Browse Code »

    Latest wandboard hardware revision is revd1, which brings the following
    new features:

    - PFUZE100 PMIC
    - AR8035 Ethernet PHY
    - Upgrade Wifi/BT chip to BCM4339/BCM43430.

    The detection mechanism is to probe the PMIC and when it is
    found, then the revision of the board is revd1.

    As the detection is done via PMIC, we need to print the board version
    at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need
    to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.

    Make the necessary adjustments for the AR8035 PHY to work on revd1.

    Based on Richard Hu's work from Technexion's U-Boot tree.

    Change is consistent with other SOCs and it is in preparation
    for adding SOMs. SOC's related files are moved from cpu/ to
    mach-imx/.

    This change is also coherent with the structure in kernel.

    There is no need to add a 100us delay after the DDR initialization.

    Other imx6 boards do not have such delay either, so simply remove it.

  • 36c0627ba   arm: imx: wandboard: fix compile error if CONFIG_VIDEO is deactivated ... Browse Code »

    When I tried to deactivate VIDEO support for the Wandboard, it still
    tried to initialize the Framebuffer and so on. That is the reason for
    the added ifdefs. CONFIG_VIDEO is enabled in the configuration as default
    and therefore nothing changes for the default user.

    The structs mx6dl_i2c2_pad_info and mx6q_i2c2_pad_info are only available
    when CONFIG_IPUV3 are set and should not be tried to access, when that
    define is not defined.

  • dac09fc10   wandboard: Make Ethernet functional again ... Browse Code »

    Since commit ce412b79e7255770 ("drivers: net: phy: atheros: add separate
    config for AR8031") ethernet does not work on mx6sabresd.

    This commit correctly assigns ar8031_config() as the configuration
    function for AR8031 in the same way as done in the Linux kernel.

    However, on wandboard design we need some additional configuration,
    such as enabling the 125 MHz AR8031 output that needs to be done
    in the board file.

    This also aligns with the same method that the kernel performs
    the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

  • ba4e159f9   wandboard: Fix hang when going into low frequency ... Browse Code »

    A kernel hang is observed when running wandboard 3.14 kernel and
    going to the lowest operational point of cpufreq:

    # ifconfig eth0 down
    # echo 1 > /sys/class/graphics/fb0/blank

    The problem is caused by incorrect setting of the REFR field
    of register MDREF. Setting it to 4 refresh commands per refresh
    cycle fixes the hang.

  • edf009373   mx6: ddr: Allow changing REFSEL and REFR fields ... Browse Code »

    Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
    REFR fields of the MDREF register as 1 and 7, respectively for
    DDR3 and 0 and 3 for LPDDR2.

    Looking at the MDREF initialization done via DCD we see that
    boards do need to initialize these fields differently:

    So introduce a mechanism for users to be able to configure
    REFSEL and REFR fields as needed.

    Keep all the mx6 SPL users in their current REF_SEL and REFR values,
    so no functional changes for the existing users.
