2022-09-28mmc: sdhci: Get rid of SDHCI_QUIRK_RESET_CMD_DATA_ON_IOSAdrian Hunter
SDHCI_QUIRK_RESET_CMD_DATA_ON_IOS is used by only ENE controllers but can be replaced by driver code. Amend the ENE code to hook the ->set_ios() mmc host operation and do the reset there.

In SDHCI specification section 3.10.1 Error Interrupt Recovery, the flow chart shows Software Reset for CMD separately and before Software Reset for DAT, so the comment "Spec says we should do both at the same time" is not correct.

2022-09-27mmc: hsq: Fix data stomping during mmc recoveryWenchao Chen
The block device uses multiple queues to access emmc. There will be up to 3 requests in the hsq of the host. The current code will check whether there is a request doing recovery before entering the queue, but it will not check whether there is a request when the lock is issued. The request is in recovery mode. If there is a request in recovery, then a read and write request is initiated at this time, and the conflict between the request and the recovery request will cause the data to be trampled.

2022-09-21mmc: core: Terminate infinite loop in SD-UHS voltage switchBrian Norris
This loop intends to retry a max of 10 times, with some implicit termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the termination condition depends on the value reported by the SD card (*rocr), which may or may not correctly reflect what we asked it to do. Needless to say, it's not wise to rely on the card doing what we expect; we should at least terminate the loop regardless. So, check both the input and output values, so we ensure we will terminate regardless of the SD card behavior. Note that SDIO learned a similar retry loop in commit 0797e5f1453b ("mmc: core: Fixup signal voltage switch"), but that used the 'ocr' result, and so the current pre-terminating condition looks like: rocr & ocr & R4_18V_PRESENT (i.e., it doesn't have the same bug.) This addresses a number of crash reports seen on ChromeOS that look like the following: ... // lots of repeated: ... <4>[13142.846061] mmc1: Skipping voltage switch <4>[13143.406087] mmc1: Skipping voltage switch <4>[13143.964724] mmc1: Skipping voltage switch <4>[13144.526089] mmc1: Skipping voltage switch <4>[13145.086088] mmc1: Skipping voltage switch <4>[13145.645941] mmc1: Skipping voltage switch <3>[13146.153969] INFO: task halt:30352 blocked for more than 122 seconds. ...

2022-09-14mmc: moxart: fix 4-bit bus width and remove 8-bit bus widthSergei Antonov
According to the datasheet [1] at page 377, 4-bit bus width is turned on by bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define BUS_WIDTH_4 BIT(1) BIT(1) does not work but BIT(2) works. This has been verified on real MOXA hardware with FTSDC010 controller revision 1_6_0. The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8 BIT(2). Additionally, 8-bit bus width mode isn't supported according to the datasheet, so let's remove the corresponding code.

2022-08-22mmc: core: Fix inconsistent sd3_bus_mode at UHS-I SD voltage switch failureAdrian Hunter
If re-initialization results is a different signal voltage, because the voltage switch failed previously, but not this time (or vice versa), then sd3_bus_mode will be inconsistent with the card because the SD_SWITCH command is done only upon first initialization. Fix by always reading SD_SWITCH information during re-initialization, which also means it does not need to be re-read later for the 1.8V fixup workaround. Note, brief testing showed SD_SWITCH took about 1.8ms to 2ms which added about 1% to 1.5% to the re-initialization time, so it's not particularly significant.

2022-08-15mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=mDavid Gow
While the sdhci-of-aspeed KUnit tests do work when builtin, and do work when KUnit itself is being built as a module, the two together break. This is because the KUnit tests (understandably) depend on KUnit, so a built-in test cannot build if KUnit is a module. Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y), which only excludes this one problematic configuration. This was reported on a nasty openrisc-randconfig run by the kernel test robot, though for some reason (compiler optimisations removing the test code?)

2022-07-26mmc: mediatek: add support for SDIO eint wakup IRQAxe Yang
Add support for eint IRQ when MSDC is used as an SDIO host. This feature requires SDIO device support async IRQ function. With this feature, SDIO host can be awakened by SDIO card in suspend state, without additional pin. MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC turn off clock and switch SDIO DAT1 pin to GPIO mode. And during resume, switch GPIO function back to DAT1 mode then turn on clock. Some device tree property should be added or modified in MSDC node to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since this feature depends on asynchronous interrupts, "wakeup-source", "keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and the interrupts list should be extended(the interrupt named with sdio_wakeup): &mmcX { ... interrupt-names = "msdc", "sdio_wakeup"; interrupts-extended = <...>, <&pio xxx IRQ_TYPE_LEVEL_LOW>; ... pinctrl-names = "default", "state_uhs", "state_eint"; ... pinctrl-2 = <&mmc2_pins_eint>; ... cap-sdio-irq; keep-power-in-suspend; wakeup-source; ... }; Co-developed-by: Yong Mao <yong.mao@mediatek.com> Signed-off-by: Yong Mao <yong.mao@mediatek.com> Reviewed-by: Chaotian Jing <chaotian.jing@mediatek.com> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Axe Yang <axe.yang@mediatek.com> Link: https://lore.kernel.org/r/20220726062842.18846-4-axe.yang@mediatek.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

Revert "mmc: sdhci-msm: Add compatible string check for sm8150" This reverts commit 5acd6adb65802cc6f9986be3750179a820580d37. 3. Revert "mmc: sdhci-msm: Add SoC specific compatibles" This reverts commit 466614a9765c6fb67e1464d0a3f1261db903834b. The oldest commit 466614a9765c ("mmc: sdhci-msm: Add SoC specific compatibles") did not specify what benefits such multiple compatibles bring, therefore assume there is none. On the other hand such approach brings a lot of churn to driver maintenance by expecting commit for every new compatible, even though it is already covered by the fallback. There is really no sense in duplicating of_device_id for each variant, which is already covered by generic compatible fallback qcom,sdhci-msm-v4 or qcom,sdhci-msm-v5.
