The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication. Currently two different frontends for the DRP interface exist. One that is only available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The other one is available on all series 7 platforms and is a softmacro with a AXI interface. This binding document describes the bindings for both of them since the bindings are very similar. Each of them needs: * A address range where the registers are mapped * An interrupt number for the device interrupt * A clock. For the the ZYNQ hardmacro interface this is the modules PCAP clock, for the AXI softmacro it is the AXI bus interface clock. Additionally the bindings specify whether an external multiplexer is used and in which mode it is used. The devicetree bindings also describe which external channels are connected and in which configuration.
