Able to build the RSB with CONFIG_SUNXI_RSB and CONFIG_MFD_AXP20X_RSB
and when I replace the above regulator with axp308 dcdc1 for mmc the
SD card is not detecting and the same issue with pine64 as well.

[    0.315257] sunxi-rsb 1f03400.rsb: RSB running at 3000000 Hz
[    0.315680] axp20x-rsb sunxi-rsb-3a3: AXP20x variant AXP803 found
[    0.317782] axp20x-rsb sunxi-rsb-3a3: AXP20X driver loaded

thanks!
