Previously, the touchscreen and ADC drivers of the LPC32xx SoC had a Kconfig conflict declared because they use the same hardware. Upon the introduction of device tree support in both drivers, the conflict must be removed to enable the same kernel to support different hardware (configured via the device tree).
