      mmc: core: Invoke mmc_pwrseq_post_power_on() prior MMC_POWER_ON state · 4febb7e2
      Ulf Hansson authored
      Host drivers have different ways to sends their "init stream" to the
      card. Some need to do it as part of a request, some do it from the
      ->set_ios() callback in the MMC_POWER_ON state and some don't send an
      "init stream" at all.
      To be able to use the reset GPIOs from the simple MMC power sequence
      provider, the card need to be powered and the "init stream" must not
      have been sent.
      To cope with these requirements, invoke mmc_pwrseq_post_power_on()
      prior we change the state to MMC_POWER_ON in mmc_power_up().
      Host drivers shall perform power up operations in the MMC_POWER_UP
      state. Unfortunate three hosts (au1xmmc, cb710-mmc and toshsd) don't
      conform to this expectation. Instead those ignore the MMC_POWER_UP
      state and delays their power up operations to the MMC_POWER_ON state.
      Those hosts needs to change their behavior to enable proper support for
      the simple MMC power sequence provider.

      mmc: core: Initial support for MMC power sequences · 3aa8793f
      Ulf Hansson authored
      System on chip designs may specify a specific MMC power sequence. To
      successfully detect an (e)MMC/SD/SDIO card, that power sequence must
      be followed while initializing the card.
      To be able to handle these SOC specific power sequences, let's add a
      MMC power sequence interface. It provides the following functions to
      help the mmc core to deal with these power sequences.
      mmc_pwrseq_alloc() - Invoked from mmc_of_parse(), to initialize data.
      mmc_pwrseq_pre_power_on()- Invoked in the beginning of mmc_power_up().
      mmc_pwrseq_post_power_on()- Invoked at the end in mmc_power_up().
      mmc_pwrseq_power_off()- Invoked from mmc_power_off().
      mmc_pwrseq_free() - Invoked from mmc_free_host(), to free data.
      Each MMC power sequence provider will be responsible to implement a set
      of callbacks. These callbacks mirrors the functions above.
      This patch adds the skeleton, following patches will extend the core of
      the MMC power sequence and add support for a specific simple MMC power
      Do note, since the mmc_pwrseq_alloc() is invoked from mmc_of_parse(),
      host drivers needs to make use of this API to enable the support for
      MMC power sequences. Moreover the MMC power sequence support depends on

      mmc: core: hold SD Clock before CMD11 during Signal · c6eb5880
      Vincent Yang authored
      Voltage Switch Procedure
      This patch is to fix an issue found on mb86s7x platforms.
      There are some UHS-1 SD memory cards sometimes cannot be detected correctly,
      e.g., Transcend 600x SDXC 64GB UHS-1 memory card.
      During Signal Voltage Switch Procedure, failure to switch is indicated
      by the card holding DAT[3:0] low.
      According to SD Host Controller Simplified Specification Version 3.00
      chapter 3.6.1, the Signal Voltage Switch Procedure should be:
      (1) Check S18A; (2) Issue CMD11; (3) Check CMD 11 response;
      (4) Stop providing SD clock; (5) Check DAT[3:0] should be 0000b;
      (6) Set 1.8V Signal Enable; (7) Wait 5ms; (8) Check 1.8V Signal Enable;
      (9) Provide SD Clock; (10) Wait 1ms; (11) Check DAT[3:0] should be 1111b;
      (12) error handling
      With CONFIG_MMC_CLKGATE=y, sometimes there is one more gating/un-gating
      SD clock between (2) and (3). In this case, some UHS-1 SD cards will hold
      DAT[3:0] 0000b at (11) and thus fails Signal Voltage Switch Procedure.
      By mmc_host_clk_hold() before CMD11, the additional gating/un-gating
      SD clock between (2) and (3) can be prevented and thus no failure at (11).
      It has been verified with many UHS-1 SD cards on mb86s7x platforms and
      works correctly.

      mmc: core: consistent handling of initial values · 2d079c43
      Johan Rudholm authored
      mmc_do_hw_reset(), mmc_power_up() and mmc_power_off() all set similar
      initial values for bus_mode, bus_width, chip_select and timing. Let's
      make this handling simpler and more consistent by sticking them
      together in a common function. This will introduce small changes in
      behavior in the following places:
        For SPI hosts, explicitly set bus_mode = MMC_BUSMODE_PUSHPULL and
        chip_select = MMC_CS_HIGH, before we left them as they were.
        For non-SPI hosts, set bus_mode = MMC_BUSMODE_PUSHPULL instead of
        MMC_BUSMODE_OPENDRAIN as before.
        These two changes should not be a problem since the device will be
        powered off anyway.
        Always set bus_mode = MMC_BUSMODE_PUSHPULL, as required by SD/SDIO
        cards. MMC cards require MMC_BUSMODE_OPENDRAIN, but this is taken
        care of by mmc_init_card() and mmc_attach_mmc().

      mmc: core: fix prepared requests while doing bkops · 64b12a68
      Srinivas Kandagatla authored
      While starting the bkops the previously prepared request should be canceled
      and restarted after the bkops. As the prepared resource might already
      setup the dma channels and ready to be started. Now with the arrival of bkops
      request this prepared request can be serviced ONLY after the bkops. So
      holding on to the prepared request in the host driver is confusing at
      this point in time, so it makes sense to cleanup such dangling requests and
      reissue this request once bkops is done.
      Canceling the prepared request would give opportunity to the host drivers
      to perform cleanup on the prepared request.
      Without this patch host drivers like mmci gets confused when a blocking
      request like send_ext_csd(CMD8) is issued while there is already a prepared
      request. With the help of this patch, the driver can better manage such
      blocking requests and cleanup the prepared requests which are not started yet.
      Without this patch I hit below crash on Qualcomm APQ8064 based IFC6410 board
      with mmci host driver.

      So, seems this bad SD card does not set valid value in related SSR / CSD register fields.
      And then the driver will set card->erase_size to 0.
      Then it triggered this divided by zero error when calculate card->pref_erase.
      Submit this patch to fix the issue.

      mmc: core: Use regulator_get_voltage() if OCR mask is empty. · 9ed7ca89
      Javier Martinez Canillas authored
      The operation conditions register (OCR) stores the voltage
      profile of the card, however the list of possible voltages
      is restricted by the voltage range supported by the supply
      used as VCC/VDD. So in mmc_vddrange_to_ocrmask() a OCR mask
      is obtained to filter the not supported voltages, from the
      value read in the host controller OCR register.
      For fixed regulators, regulator_list_voltage() returns the
      fixed output for the first selector but this doesn't happen
      for switch (FET) regulators that obtain their voltage from
      their parent supply. A call to regulator_get_voltage() is
      needed in this case so the regulator core can return the
      FET's parent supply voltage output.
      This change is consistent with the fact that for other
      fixed regulators (that are not FETs) the OCR mask is
      returned even when mmc_regulator_set_ocr() checks if the
      regulator is fixed before calling regulator_set_voltage().
      Without this patch, the following warning is reported when
      a FET is used as a vmmc-supply:
      dwmmc_exynos 12220000.mmc: Failed getting OCR mask: -22

      mmc: core: Remove fixed voltage regulator logic · ca6429d4
      Tim Kryger authored
      There is no need for regulator consumers to include special logic for
      fixed voltage regulators as they support regulator_set_voltage() just
      like their non-fixed regulator counterparts.

      mmc: core: Use maximum timeout values in case TACC field is zero · f7bf11a3

      When plugging a specific micro SD card at MMC socket of a custom i.MX28 board,
      we get the following kernel warning:

      The error is due to an invalid value in CSD register of a specific 2GB
      micro SD card. The CSD version of this card is 1.0 but the TACC field
      has the invalid value 0.
      Since the kernel is making use of this TACC field to calculate the SD
      card timeout, an invalid value 0 leads to a warning at
      mxs_ns_to_ssp_ticks() and later the following misleading error message
      appears in a loop:
      mxs-mmc 80010000.ssp: card claims to support voltages below defined range
      mxs-mmc 80010000.ssp: no support for card's volts
      mmc0: error -22 whilst initialising MMC card
      This error is only found on this 2GB SD card on mxs platform.
      On x86 this card works without any problems.
      The following patch based on the work of Peter Chan and Otavio Salvador.
      It catches the case that the determined timeout is still 0 and sets it
      to a valid value.
      Successful tested on a i.MX28 board.

      mmc: Delay the card_event callback into the mmc_rescan worker · fa372a51

      This change removes the callback from atomic context which it doesn't
      need to be in, and puts it in line with the debounced rescan.
      This code is based on these e-mail threads with Christian Daudt:
