Subject: [RFC PATCH net-next] net: ethernet: ti: cpsw: drop TI_DAVINCI_CPDMA config option
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.
Signed-off-by: Grygorii Strashko <grygorii.strashko@...com>

It's been marked as RFC as I've had to change davinci_emac.c module name
to "ti_davinci_emac". if no objection - I'd like to do the same for ALE module also
and then resend.
