Subject[PATCH net-next 02/19] net: ethernet: ti: cpsw: drop TI_DAVINCI_CPDMA config option
Date
Both drivers CPSW and EMAC can't work without CPDMA, hence simplify build
of those drivers by always linking davinci_cpdma and drop TI_DAVINCI_CPDMA
config option.
Note. the davinci_emac driver module was changed to "ti_davinci_emac" to
make build work.
