error: recursive dependency detected!
	symbol REGMAP default is visible depending on REGMAP_MMIO
	symbol REGMAP_MMIO is selected by MUX_MMIO
	symbol MUX_MMIO depends on MULTIPLEXER
	symbol MULTIPLEXER is selected by MDIO_BUS_MUX_MULTIPLEXER
	symbol MDIO_BUS_MUX_MULTIPLEXER depends on MDIO_BUS
	symbol MDIO_BUS is selected by REGMAP
