Indeed the STMMAC driver doesn't take the vendor-specific compatible string into account to parse the "snps,tso" boolean property. It just makes sure the node is compatible with DW MAC 4.x, 5.x and DW xGMAC IP-cores. The original allwinner sunXi bindings file also didn't have the TSO-related property declared. Taking all of that into account fix the conditional statement so the TSO-property would be evaluated for the compatibles having the corresponding IP-core version. While at it move the whole allOf-block from the tail of the binding file to the head of it, as it's normally done in the most of the DT schemas. Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru> --- Note this won't break the bindings description, since the "snps,tso" property isn't parsed by the Allwinner SunX GMAC glue driver, but only by the generic platform DT-parser. Changelog v2: - Use correct syntax of the JSON pointers, so the later would begin with a '/' after the '#'. --- .../devicetree/bindings/net/snps,dwmac.yaml | 52 +++++++++---------- 1 file changed, 24 insertions(+), 28 deletions(-)
