* da850/omap-l138: Enable auto negotiation in RMII modeRajashekhara, Sudhakar2012-07-07-0/+8
| | | | | | | | | | | | On DA850/OMAP-L138 it was observed that in RMII mode, auto negotiation was not performed. This patch enables auto negotiation in RMII mode. Without this patch, EMAC initialization takes more time and sometimes tftp fails in RMII mode.

* davinci_emac: hardcode 100Mbps for AM35xx and RMIIIlya Yanok2011-12-06-1/+2

* davinci_emac: fix for running with dcache enabledIlya Yanok2011-12-06-2/+39
| | | | | | | | | | | | DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache enabled by default. So we have to take care and flush/invalidate the cache before/after the DMA operations. Please note that the receive buffer alignment to 32 byte boundary comes from the old driver version I don't know if it is really needed or alignment to cache line size is enough.

This patch moves common defines from arch-davinci/emac_defs.h to drivers/net/davinci_emac.h DaVinci specific PHY drivers hacked to include the new header. We might want to switch to phylib in future.

* da850: Add RMII support for EMACSudhakar Rajashekhara2010-11-30-1/+40
| | | | | | | | | | | | | | | | | | | | | | | This patch is a port of the work by Sudhakar Rajeshekhara in commit ab3effbcad8851cc65dc5241a01c064d2030a3b2 of git://arago-project.org/git/people/sandeep/u-boot-davinci.git. The da850 UI board has on it an RMII PHY which can be used if the MDC line to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by configuring the values of some GPIO pins on the IO expander of the UI board. This patch implements disabling that line via GPIO2[6], configuring the UI board's IO expander and setting only the pinmux settings that are needed for RMII operation. Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

* davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddrBen Gardiner2010-10-11-41/+39
| | | | | | | | | | | | | | | | | | | | | | This patch proposes to migrate the davinci_emac driver to using the eth_device->write_hwaddr function pointer as suggested by Ben Warren. All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.
