* drivers/net: Remove casts of void *Joe Perches2011-06-211-1/+1

* net: davinci_emac:Fix translation logic for buffer descriptorSriram2011-03-221-3/+8
| | | | | | | | | | | | | | | With recent changes to the driver(switch to new cpdma layer), the support for buffer descriptor address translation logic is broken. This affects platforms where the physical address of the descriptors as seen by the DMA engine is different from the physical address. Original Patch adding translation logic support: Commit: ad021ae8862209864dc8ebd3b7d3a55ce84b9ea2 Signed-off-by: Sriramakrishnan A G <srk@ti.com> Tested-By: Sekhar Nori <nsekhar@ti.com> Signed-off-by: David S.

* net: davinci_emac: separate out cpdma codeCyril Chemparathy2010-09-241-0/+965
In addition to being embedded into the EMAC controller, the CPDMA hardware block is used in TI's CPSW switch controller. Fortunately, the programming interface to this hardware block remains pretty nicely consistent across these devices. This patch adds a new CPDMA services layer, which can then be reused across EMAC and CPSW drivers.
