There are 4 SD/MMC controller present in this SoC but only 2 are enabled currently for Bubblegum96 board to access uSD and onboard eMMC. SDIO support for this driver is not currently implemented. Note: Currently, driver uses 2 completion mechanisms for maintaining the coherency between SDC and DMA interrupts and I know that it is not efficient. Hence, I'd like to hear any suggestions for reimplementing the logic if anyone has. With this driver, this patchset also fixes one clk driver issue and enables the Actions Semi platform in ARM64 defconfig. Thanks, Mani Changes in v3: * Incorporated a review comment from Andreas on board dts patch * Modified the MAINTAINERS entry for devicetree YAML binding Changes in v2: * Converted the devicetree bindings to YAML * Misc changes to bubblegum devicetree as per the review from Andreas * Dropped the read/write wrappers and renamed all functions to use owl- prefix as per the review from Ulf * Renamed clk_val_best to owl_clk_val_best and added Reviewed-by tag from Stephen Manivannan Sadhasivam (7): clk: actions: Fix factor clk struct member access dt-bindings: mmc: Add Actions Semi SD/MMC/SDIO controller binding arm64: dts: actions: Add MMC controller support for S900 arm64: dts: actions: Add uSD and eMMC support for Bubblegum96 mmc: Add Actions Semi Owl SoCs SD/MMC driver MAINTAINERS: Add entry for Actions Semi SD/MMC driver and binding arm64: configs: Enable Actions Semi platform in defconfig .../devicetree/bindings/mmc/owl-mmc.yaml | 62 ++ MAINTAINERS | 2 + .../boot/dts/actions/s900-bubblegum-96.dts | 62 ++ arch/arm64/boot/dts/actions/s900.dtsi | 45 ++ arch/arm64/configs/defconfig | 1 + drivers/clk/actions/owl-factor.c | 7 +- drivers/mmc/host/Kconfig | 8 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/owl-mmc.c | 696 ++++++++++++++++++ 9 files changed, 880 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/mmc/owl-mmc.yaml create mode 100644 drivers/mmc/host/owl-mmc.c -- 2.17.1
