[PATCH 0/2] Fix dtc warnings when building the LAN966x device tree overlay

Posted by Herve Codina 3 weeks, 6 days ago

dtc generates 3 kinds of warnings when it builds the LAN966x dtso.

- missing or empty reg/ranges property
    .../pci-ep-bus@0/cpu_clk: missing or empty reg/ranges property
    .../pci-ep-bus@0/ddr_clk: missing or empty reg/ranges property
    .../pci-ep-bus@0/sys_clk: missing or empty reg/ranges property
  Patch 1 in this series fixes these warnings

- Missing interrupt-parent
   .../pci-ep-bus@0/oic@e00c0120: Missing interrupt-parent
  This warning was quickly silenced by Philipp [1].
  Patch 2 in this series fixes the warning and should replace the patch
  applied by Philipp to silence the warning.

- Warning (avoid_unnecessary_addr_size)
   /fragment@0/__overlay__: unnecessary #address-cells/#size-cells without "ranges", "dma-ranges" or child "reg" property
  This warning should be fixed in dtc.
  A patch has already be sent by Philip to fix it [2].
