The maximum voltage value for buck8 regulator on Odroid XU3/XU4 boards is set too low. Increase it to the 2000mV as specified on the board schematic. So far the board worked fine, because of the bug in the PMIC driver, which used incorrect step value for that regulator. It interpreted the voltage value set by the bootloader as 1225mV and kept it unchanged. The regulator driver has been however fixed recently in the commit56b5d4ea77("regulator: s2mps11: Fix steps for buck7, buck8 and LDO35"), what results in reading the proper buck8 value and forcing it to 1500mV on boot. This is not enough for proper board operation and results in eMMC errors during heavy IO traffic. Increasing maximum voltage value for buck8 restores original driver behavior and fixes eMMC issues.
