The Davinci EMAC peripheral is also available on other TI platforms -
notably TI AM3517 SoC. The following series of patches modify the driver
suitably to make it platform agnostic.
This patch has been generated against the tip of linux-davinci git.
Sriramakrishnan (3):
TI Davinci EMAC : Re-use driver for other platforms.
TI Davinci EMAC : add platform specific interrupt enable/disable
logic.
TI Davinci EMAC : Abstract Buffer address translation logic.
