0001 Altera FPGA/HPS Bridge Driver
0002
0003 Required properties:
0004 - regs          : base address and size for AXI bridge module
0005 - compatible    : Should contain one of:
0006                   "altr,socfpga-lwhps2fpga-bridge",
0007                   "altr,socfpga-hps2fpga-bridge", or
0008                   "altr,socfpga-fpga2hps-bridge"
0009 - resets        : Phandle and reset specifier for this bridge's reset
0010 - clocks        : Clocks used by this module.
