The series starts with fixes of the PBL (Programmable DMA Burst length) DT-property, which is supposed to be defined for each DW *MAC IP-core, but not only for a Allwinner sun* and Ingenic GMAC and DW xGMAC. The number of possible PBL values need to be also extended in accordance with the DW *MAC manual. Then the TSO flag property should be also declared free of the vendor-specific conditional schema, because the driver expects the compatible string to have the IP-core version specified anyway and none of the glue-drivers refer to the property directly. Moreover the original Allwinner sunXi bindings file didn't have the TSO-related property declared. So we can freely do that. Then in order to improve the DT-bindings maintainability we suggest to split up the generic DT-properties and generic DT-nodes schema leaving the properties definition in the "snps,dwmac.yaml" file and moving the generic DW *MAC DT-nodes bindings validation in the dedicated DT-schema "snps,dwmac-generic.yaml". We've found out that the DW MAC bindings don't provide a correct description of the System/CSR clocks and a comprehensive enough description of the clock-related "snps,clk-csr" property. So in order to have more descriptive bindings we suggest to add a bit more details about the App/CSR clocks and CSR-MDC divider property. Then seeing the any DW MAC IP-core revision can be equipped with an external Tx/Rx clock sources we suggest to add the "tx"/"rx" clocks declaration into the generic DW MAC DT-schema. Afterwards a set of the AXI-bus config property cleanups are introduced. First we suggest to drop the "snps,axi-config" property description since it duplicates the stmmac-axi-config sub-node DT-bindings. Second the unevaluatedProperties property is replaced with additionalProperties as more suitable for the "stmmac-axi-config" schema. Third the proper constraints are added to the properties of the "stmmac-axi-config" sub-node. Then three patches concerning the MTL Tx/Rx queue configs go, which add the sub-nodes properties constraints and fix the MTL Tx queue properties description. The next patch converts the DW MAC DT-bindings to using the "flag" definition instead of the native boolean type for relevant properties. It's done for the sake of the DT-schema unification. The series is closed with the two patches concerning the MTL queue config properties dependencies. First one provides a simpler construction for the MTL queue properties inter-dependencies. The second one adds the dependencies definition for the MTL Tx queue CBS-algo properties.
