Hi, This patch series adds Allwinner sun7i support to stmmac. The Allwinner sun7i SoC A20 integrates an early version of dwmac IP from Synopsys. On top of that is a hardware glue layer. This layer needs to be configured before the dwmac can be used. The glue layer is implemented with existing callbacks in stmmac platform data. Hardware feature flags are also passed to the driver through platform data. As suggested by Maxime, the platform data is tied to our compatible string. Minimal modifications to stmmac core are made. This version of dwmac IP requires store and forward DMA mode. The relevant device tree property was documented, but not implemented. The second patch adds this to stmmac platform driver. During testing, with stmmac built as a module, loading the driver fails during the hardware probe phase. The main clock is not enabled, and the hardware returns bogus results. The first patch addresses this. Comments?
