Merge tag 'mmc-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
"MMC core:
- Extend slot-gpio to be used for host specific card detect interrupts
- Align to common busy polling behaviour for mmc ioctls
- Suggest the BFQ I/O scheduler to be built along with MMC/SD support
- Add devm_mmc_alloc_host() to enable further cleanups in host drivers

MMC host:
- atmel-mci: Fix race condition when stopping/starting a command
- dw_mmc-starfive: Add new driver to support the StarFive JH7110 variant
- dw_mmc-rockchip: Add support for the RK3588 variant
- jz4740: Add support for the vqmmc power supply
- meson-gx: Convert the DT bindings to the dt-schema
- meson-gx: Enable the platform interrupt to be used for card detect
- moxart: Set the supported maximum request/block/segment sizes
- renesas,sdhi: Add support for the RZ/V2M variants
- sdhci: Rework code to drop SDHCI_QUIRK_MISSING_CAPS
- sdhci-esdhc-imx: Improve tuning logic support
- sdhci-msm: Add support for the IPQ5332 and the IPQ9574 variants
- sdhci-of-dwcmshc: Add the missing device table IDs for acpi
- sdhci-of-dwcmshc: Improve clock support for the Rockchip variant
- sdhci-of-dwcmshc: Enable support of V4 host for the BlueField-3 variant
- sdhci-pxav2: Add support for the PXA168 V1 variant
- sdhci-pxav2: Add support for SDIO IRQs for the PXA168 V1 variant
- uniphier-sd: Add support for SD UHS-I speed modes"
