  • 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.

  • 88a57125f   mmc: sdhci: add SDHCI_QUIRK_BROKEN_HISPD_MODE ... Browse Code »

    Some IP-core implementations of the SDHCI have different troubles on the
    silicon where they are placed.

    On ZYNQ platform for example Xilinx doesn't accept the hold timing of an
    eMMC chip which operates in High-Speed mode and must be forced to
    operate in non high-speed mode. To get rid of this
    "SDHCI_QUIRK_BROKEN_HISPD_MODE" is introduced.

    For more details about this refer to the Xilinx answer-recor #59999
    https://www.xilinx.com/support/answers/59999.html

    This commit:
    - doesn't set HISPD bit on the host-conroller
    - reflects this fact within the host-controller capabilities

    Upon this the layer above (mmc-driver) can setup the card correctly.

    Otherwise the MMC card will be switched into high-speed mode and causes
    possible timing violation on the host-controller side.

  • 210841c69   mmc: sdhci: Add support for optional controller specific set_ios_post() ... Browse Code »

    Some SDHCI drivers might need to do some special controller configuration
    after the common clock set_ios() function has been called (speed / width
    configuration). This patch adds a call to the newly created function
    set_ios_port() when its configured in the host driver.

    This will be used by the Xenon SDHCI controller driver used on the
    Marvell Armada 3700 and 7k/8k ARM64 SoCs.

  • a0d0d86f5   mmc: atmel_sdhci: Convert to the driver model support ... Browse Code »

    Convert the driver to the driver model while retaining the existing
    legacy code. This allows the driver to support boards that have
    converted to driver model as well as those that have not.

  • 93bfd6167   mmc: Split mmc struct, rework mmc initialization (v2) ... Browse Code »

    The way that struct mmc was implemented was a bit of a mess;
    configuration and internal state all jumbled up in a single structure.

    On top of that the way initialization is done with mmc_register leads
    to a lot of duplicated code in drivers.

    Typically the initialization got something like this in every driver.

    struct mmc *mmc = malloc(sizeof(struct mmc));
    memset(mmc, 0, sizeof(struct mmc);
    /* fill in fields of mmc struct */
    /* store private data pointer */
    mmc_register(mmc);

    By using the new mmc_create call one just passes an mmc config struct
    and an optional private data pointer like this:

    struct mmc = mmc_create(&cfg, priv);

    All in tree drivers have been updated to the new form, and expect
    mmc_register to go away before long.

    Changes since v1:

    * Use calloc instead of manually calling memset.
    * Mark mmc_register as deprecated.

  • 13243f2ea   mmc: sdhci: Add a quirk to add delay during completion of sdhci_send_cmd ... Browse Code »

    MMC host controller requires a delay between every sdhci_send_cmd()
    execution. In s5p_mmc driver (s5p_sdhci replaces this driver), a delay
    of 1000us was provided after every mmc_send_cmd() call. Adding a quirk
    in current sdhci driver to replicate the behaviour.

    Without this delay, MMC initialization on Origen board fails with
    following error messages.

    Timeout for status update!
    mmc fail to send stop cmd

    When response type is R1b, mask value is added the SDHCI_INT_DAT_END.
    but in while(), didn't check that flag.
    So sdhci controller didn't work fine.
    CMD6 didn't always complete.

    So add the quirks for broken r1b response
    and add the timeout value to prevent the infinite loop.
