Commitd4ec0cb050("ARM: dts: exynos: Add support for the touch-sensitive buttons on Midas family") added a new fixed regulator ("voltage-regulator-6") to base "midas" .dtsi, but it didn't update the clients of that .dtsi, which define their own fixed regulators starting from the "voltage-regulator-6". This results in aliasing of the regulator dt nodes and breaks operation of OLED panel due to lack of power supply. Fix this by increasing the numbers in the fixed regulator names for those boards.
