The device tree (DT) data structure consists of nodes with properties that describe a hardware. The Linux kernel uses the device tree to support a wide range of hardware configurations.

In FPGAs, it is possible to have different combinations of peripheral logics, each using a different configuration. For all the different combinations, the device tree generator (DTG) generates the .dts/.dtsi device tree files.

The following is a list of the .dts/.dtsi files generated by the device tree generator:

  • pl.dtsi: Contains all the memory mapped peripheral logic (PL) IPs.
  • pcw.dtsi: Contains the dynamic properties for the PS IPs.
  • system-top.dts: Contains the memory, boot arguments, and command line parameters.
  • zynqmp.dtsi: Contains all the PS specific and the CPU information.
  • zynqmp-clk-ccf.dtsi: Contains all the clock information for the PS peripheral IPs.
