development kit, improving storage performance for both SD cards and eMMC devices.
The Cadence SDHCI controller on Agilex5 supports UHS-I modes for SD cards (SDR50, SDR104) and HS200/HS400 modes for eMMC. This series adds the necessary device tree properties and defconfig changes to enable these modes. Changes include: - Fix DT property naming to use hyphens instead of underscores - Enable SD card UHS-I SDR50 and SDR104 modes with PHY timing config - Enable eMMC HS200 and HS400 modes with PHY timing config Tested on Agilex5 SoCDK board with: - SD card: UHS-I SDR104 mode at 200MHz - eMMC: HS400 mode at 200MHz Tanmay Kathpalia (3): arm: dts: agilex5: Fix DT property naming convention arm: agilex5: Enable SD card UHS mode support arm: agilex5: Enable eMMC HS200 and HS400 mode support .../arm/dts/socfpga_agilex5_socdk-u-boot.dtsi | 31 ++++++++++++++++--- arch/arm/dts/socfpga_agilex5_socdk_emmc.dts | 28 ++++++++++++++++- configs/socfpga_agilex5_defconfig | 2 ++ configs/socfpga_agilex5_emmc_defconfig | 2 ++ 4 files changed, 58 insertions(+), 5 deletions(-) -- 2.43.7
