mmc: sdhci-pci-gli: GL9767: Fix initializing the UHS-II interface during a power-on

2025-09-12T13:00:52Z

According to the power structure of IC hardware design for UHS-II interface, reset control and timing must be added to the initialization process of powering on the UHS-II interface.

mmc: sdhci-uhs2: Fix calling incorrect sdhci_set_clock() function

Fix calling incorrect sdhci_set_clock() in __sdhci_uhs2_set_ios() when the vendor defines its own sdhci_set_clock(). Fixes: 10c8298a052b ("mmc: sdhci-uhs2: add set_ios()") Cc: stable@vger.kernel.org # v6.13+ Signed-off-by: Ben Chuang Acked-by: Adrian Hunter Signed-off-by: Ulf Hansson

mmc: sdhci: Move the code related to setting the clock from sdhci_set_ios_common() into sdhci_set_ios()

2025-09-12T13:00:52Z

The sdhci_set_clock() is called in sdhci_set_ios_common() and __sdhci_uhs2_set_ios(). According to Section 3.13.2 "Card Interface Detection Sequence" of the SD Host Controller Standard Specification Version 7.00, the SD clock is supplied after power is supplied, so we only need one in __sdhci_uhs2_set_ios(). Let's move the code related to setting the clock from sdhci_set_ios_common() into sdhci_set_ios() and modify the parameters passed to sdhci_set_clock() in __sdhci_uhs2_set_ios().

mmc: mvsdio: Fix dma_unmap_sg() nents value

2025-09-12T12:04:22Z

The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned. Fixes: 236caa7cc351 ("mmc: SDIO driver for Marvell SoCs") Signed-off-by: Thomas Fourier Reviewed-by: Linus Walleij Cc: stable@vger.kernel.org Signed-off-by: Ulf Hansson

mmc: sdhci_am654: Disable HS400 for AM62P SR1.0 and SR1.1

2025-08-21T09:07:16Z

This adds SDHCI_AM654_QUIRK_DISABLE_HS400 quirk which shall be used to disable HS400 support. AM62P SR1.0 and SR1.1 do not support HS400 due to errata i2458 [0] so disable HS400 for these SoC revisions.

mmc: sdhci-of-arasan: Ensure CD logic stabilization before power-up

2025-08-18T09:43:27Z

During SD suspend/resume without a full card rescan (when using non-removable SD cards for rootfs), the SD card initialization may fail after resume. This occurs because, after a host controller reset, the card detect logic may take time to stabilize due to debounce logic. Without waiting for stabilization, the host may attempt powering up the card prematurely, leading to command timeouts during resume flow. Add sdhci_arasan_set_power_and_bus_voltage() to wait for the card detect stable bit before power up the card. Since the stabilization time is not fixed, a maximum timeout of one second is used to ensure sufficient wait time for the card detect signal to stabilize.

mmc: sdhci-pci-gli: GL9763e: Mask the replay timer timeout of AER

2025-08-18T09:38:24Z

Due to a flaw in the hardware design, the GL9763e replay timer frequently times out when ASPM is enabled. As a result, the warning messages will often appear in the system log when the system accesses the GL9763e PCI config. Therefore, the replay timer timeout must be masked.
