git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull KUnit fixes from Shuah Khan: "Fix for a mmc test and to load .kunit_test_suites section when CONFIG_KUNIT=m, and not just when KUnit is built-in" * tag 'linux-kselftest-kunit-fixes-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: module: kunit: Load .kunit_test_suites section when CONFIG_KUNIT=m mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=m
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?) I wasn't able to reproduce it locally on x86: https://lore.kernel.org/linux-mm/202207140122.fzhlf60k-lkp@intel.com/T/ Fixes: 291cd54e5b05 ("mmc: sdhci-of-aspeed: test: Use kunit_test_suite() macro") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: David Gow <davidgow@google.com> Acked-by: Andrew Jeffery <andrew@aj.id.au> Acked-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2022-08-15mmc: sdhci-of-dwcmshc: Re-enable support for the BlueField-3 SoCLiming Sun
The commit 08f3dff799d4 (mmc: sdhci-of-dwcmshc: add rockchip platform support") introduces the use of_device_get_match_data() to check for some chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI. To fix the problem, let's add the ACPI match data and the corresponding quirks to re-enable the support for the BlueField-3 SoC.

2022-08-15mmc: mtk-sd: Clear interrupts when cqe off/disableWenbin Mei
Currently we don't clear MSDC interrupts when cqe off/disable, which led to the data complete interrupt will be reserved for the next command. If the next command with data transfer after cqe off/disable, we process the CMD ready interrupt and trigger DMA start for data, but the data complete interrupt is already exists, then SW assume that the data transfer is complete, SW will trigger DMA stop, but the data may not be transmitted yet or is transmitting, so we may encounter the following error: mtk-msdc 11230000.mmc: CMD bus busy detected.

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 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.

2022-07-13mmc: sdhci-omap: Fix a lockdep warning for PM runtime initTony Lindgren
We need runtime PM enabled early in probe before sdhci_setup_host() for sdhci_omap_set_capabilities(). But on the first runtime resume we must not call sdhci_runtime_resume_host() as sdhci_setup_host() has not been called yet. Let's check for an initialized controller like we already do for context restore to fix a lockdep warning.

If we reset because of an error, we need to preserve values for the clock frequency. Otherwise, glitches may be seen on the bus. To achieve that, we introduce a 'preserve' parameter to the reset function and the IP core specific reset callbacks to handle everything accordingly.

2022-07-12mmc: host: Improve I/O read/write performance for GL9763EJason Lai
Due to flaws in hardware design, GL9763E takes long time to exit from L1 state. The I/O performance will suffer severe impact if it often enter and exit L1 state during I/O requests. To improve I/O read/write performance and take battery life into account, let's turn on GL9763E L1 negotiation before entering runtime suspend and turn off GL9763E L1 negotiation while executing runtime resume. That is to say, GL9763E will not enter L1 state when executing I/O requests and enter L1 state when PCIe bus idle.
