* net, davinci_emac: let the EMAC detect the PHYsHeiko Schocher2011-09-30-0/+3
| | | | | | | | | | | Once the MDIO state machine has been initialized and enabled, it starts polling all 32 PHY addresses on the MDIO bus, looking for an active PHY. Add a 5 ms delay, so all PHYs are for sure detected. This problem was detected on the cmc board with a KSZ8864 switch.

* net, davinci_emac: make less verbose - turn printf() into debug()Heiko Schocher2011-09-30-1/+1
| | | | | | | | | | | | | | | | | | | | The PHY driver was too verbose and corrupted the boot message display like this: ... Net: Ethernet PHY: KSZ8873 @ 0x02 DaVinci-EMAC ... Turn printf() into debug() so we get the expected output again: ... Net: DaVinci-EMAC ...

* da850: fix the channel number for EMAC teardown initNagabhushana Netagunte2011-09-04-2/+2
| | | | | | | | | | TX and RX channel numbers programmed as '1' during EMAC teardown initialization is wrong. This patch fixes the same by setting channel number to '0' which is used by U-boot.

* ea20: fix undefined PHY_* errorsBen Gardiner2011-04-11-3/+3
| | | | | | | | | | | This patch fixes ea20 after 8ef583a0351590a91394499eb5ca2ab8a703d959 where the u-boot custom PHY_ macros were replaced with those of linux/mii.h MII_ definitions except in the RMII support for davinci_emac. Probably also due to the merge path of changes in 2010.12. Signed-off-by: Ben Gardiner<bengardiner@nanometrics.ca> CC: Mike Frysinger <vapier@gentoo.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* DaVinci DM6467: Added ET1011C (LSI) PHY supportSandeep Paulraj2011-02-02-0/+7
| | | | | | | | | | Added arch/arm/cpu/arm926ejs/davinci/et1011c.c for handling ET1011C gigabit phy. which overrides get_link_speed function from default implementation. This enables output of 125 MHz reference clock on SYS_CLK pin. Signed-off-by: Prakash PM <prakash.pm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* DaVinci EMAC: Add name to Ethernet deviceSandeep Paulraj2011-02-02-0/+1
| | | | | | | | | | | | Adds "DaVinci-EMAC" as the name of the device so that it gets printed as "Using DaVinci-EMAC device" during network access (dhcp, tftp) instead of empty name in "Using" statement.This name also gets reflected in 'ethact' env variable.

* DaVinci EMAC: Fix davinci_eth_gigabit_enableSandeep Paulraj2011-02-02-3/+4
| | | | | | | | | | | Enabling the gigabit was overwriting the previous configuration by setting up only GIGAFORCE and GIG bits of MAC control register. Modified to retain previous configuration while gigabit enabling. Signed-off-by: Prakash PM <prakash.pm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* miiphy: convert to linux/mii.hMike Frysinger2011-01-09-8/+8
| | | | | | | | The include/miiphy.h header duplicates a lot of things from linux/mii.h. So punt all the things that overlap to keep the API simple and to make merging between U-Boot and Linux simpler. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* 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.
