The following speed modes are now supported in J7200 SoC, - HS200 and HS400 modes at 1.8 V card voltage, in MMCSD0 subsystem [1]. - UHS-I speed modes in MMCSD1 subsystem [1]. Add support for UHS-I modes by adding voltage regulator device tree nodes and corresponding pinmux details, to power cycle and voltage switch cards. Also set respective tags in sdhci0 and remove no-1-8-v tag from sdhci1 device tree nodes.
