* net: davinci_emac: cleanup unused mdio emac codeCyril Chemparathy2010-09-241-3/+0
| | | | | | | | | | | This patch removes code that has been rendered useless by the previous patches in this series. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Acked-by: David S. Miller <davem@davemloft.net> Tested-by: Michael Williamson <michael.williamson@criticallink.com> Tested-by: Caglar Akyuz <caglarakyuz@gmail.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* net: davinci_emac: switch to new mdioCyril Chemparathy2010-09-241-0/+9
| | | | | | | | | | | | | | | | | | This patch switches the emac implementation over to the newly separated MDIO driver. With this, the mdio bus frequency defaults to a safe 2.2MHz. Boards may optionally specify a bus frequency via platform data. The phy identification scheme has been modified to use a phy bus id instead of a mask. This largely serves to eliminate the "phy search" code in emac init. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Acked-by: David S.

* net: davinci_emac: separate out davinci mdioCyril Chemparathy2010-09-241-0/+4
| | | | | | | | | | | | | | Davinci's MDIO controller is present on other TI devices, without an accompanying EMAC. For example, on tnetv107x, the same MDIO module is used in conjunction with a 3-port switch hardware. By separating the MDIO controller code into its own platform driver, this patch allows common logic to be reused on such platforms.

* TI Davinci EMAC : Abstract Buffer address translation logic.Sriramakrishnan2010-02-041-0/+1
| | | | | | | | | | | | | When programming the DMA engine, the next pointers must be programmed with physical address as seen from the DMA master address space. This address may be different from physical address of the buffer RAM area. This patch abstracts the buffer address translation logic.

* TI Davinci EMAC : add platform specific interrupt enable/disable logic.Sriramakrishnan2010-02-041-0/+2
| | | | | | | | | | | | On certain SOCs, the EMAC controller is interfaced with a wrapper logic for handling interrupts. This patch implements a platform specific hook to cater to platforms that require custom interrupt handling logic Signed-off-by: Sriramakrishnan <srk@ti.com> Acked-by: Chaithrika U S <chaithrika@ti.com> Acked-by: David S.

* TI Davinci EMAC : Re-use driver for other platforms.Sriramakrishnan2010-02-041-0/+36
The davinci EMAC peripheral is also available on other TI platforms -notably TI AM3517 SoC. This patch modifies the config option and the platform structure header files so that the driver can be reused on non-davinci platforms as well.
