The patch adds eMMC support for Sparx5, by adding a driver for the SoC SDHCI controller, DT configuration and DT binding documentation.
Changes in v5: - DT+yaml: Change (mmc|sdhci)@600800000 to mmc0@600800000 - Add missing "static" attribute to probe function - Drop MMC_SDHCI_IO_ACCESSORS, as it is not required (anymore) Changes in v4: - Disable clock if sdhci_add_host() fails - Remove dev_err if sdhci_add_host() fails Changes in v3: - Add dt-bindings for property "microchip,clock-delay" - Enforce "microchip,clock-delay" valid range in driver - Removed a noisy pr_debug() in sdhci_sparx5_adma_write_desc() Changes in v2: - Changes in driver as per review comments - Drop debug code - Drop sysfs code - use usleep_range() - use mmc_hostname() in pr_debug() - Remove deactivated code - Minor cosmetics Lars Povlsen (3): dt-bindings: mmc: Add Sparx5 SDHCI controller bindings sdhci: sparx5: Add Sparx5 SoC eMMC driver arm64: dts: sparx5: Add Sparx5 eMMC support .../mmc/microchip,dw-sparx5-sdhci.yaml | 65 +++++ arch/arm64/boot/dts/microchip/sparx5.dtsi | 24 ++ .../boot/dts/microchip/sparx5_pcb125.dts | 23 ++ .../boot/dts/microchip/sparx5_pcb134_emmc.dts | 23 ++ .../boot/dts/microchip/sparx5_pcb135_emmc.dts | 23 ++ drivers/mmc/host/Kconfig | 12 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/sdhci-of-sparx5.c | 269 ++++++++++++++++++ 8 files changed, 440 insertions(+) create mode 100644 Documentation/devicetree/bindings/mmc/microchip,dw-sparx5-sdhci.yaml create mode 100644 drivers/mmc/host/sdhci-of-sparx5.c -- 2.27.0
