(This is a resend of an identical patch set, sent at a time where Sparx5 support was not integrated yet. With the Sparx5 clock driver and associated header now in place in the v5.9rc series, the driver is now resubmitted for inclusion). The patch adds eMMC support for Sparx5, by adding a driver for the SoC SDHCI controller, DT configuration and DT binding documentation. 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 | 13 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/sdhci-of-sparx5.c | 269 ++++++++++++++++++ 8 files changed, 441 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
