Currently, for JH7110 boards with EMMC slot, vqmmc voltage for EMMC is fixed to 1.8V, while the spec needs it to be 3.3V on low speed mode and should support switching to 1.8V when using higher speed mode. Since there are no other peripherals using the same voltage source of EMMC's vqmmc(ALDO4) on every board currently supported by mainline kernel,
I should've asked last time around, does the star64 also support 3.3 volts?
regulator-max-microvolt of ALDO4 should be set to 3.3V.
