iio: ADC driver for EP93xx SoC

This series prepares the necessary infrastructure for ADC platform device on Cirrus Logic EP93xx family of SoCs and adds the driver for ADC device using IIO subsystem.

Alexander Sverdlin (5):
clk: ep93xx: Implement clk_get_parent()
clk: ep93xx: Add ADC clock
ep93xx: Add ADC platform device support to core
edb93xx: Add ADC platform device
iio: adc: New driver for Cirrus Logic EP93xx ADC
