Maxim 1586 regulator driver
The Maxim 1586 regulator is a voltage regulator with 2 voltage outputs, specially suitable for Marvell PXA chips. One output is in the range of required VCC_CORE by the PXA27x chips, the other in the VCC_USIM required as well by PXA27x chips. The chip is controlled through the I2C bus.
