* netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328Anton Vorontsov2008-07-231-5/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drivers were touching net queue before it has been started, so without this patch, the drivers will potentially WARN at net/core/dev.c:1328. I don't have the hardware for the drivers below, so this patch is untested, and thus should be carefully peer reviewed. tc35815.c au1000_eth.c bfin_mac.c macb.c ^ The four drivers are using phylib, they're calling netif_start_queue() in open() callback. So trivially remove netif_tx_schedule_all(). Phylib will handle netif_carrier_*(). cpmac.c fec_mpc52xx.c fs_enet/fs_enet-main.c sh_eth.c ^ The same as above, but these were also needlessly calling netif_carrier_*() functions. So removed queue calls and also remove carrier calls, since phylib will handle it. fs_enet-main.c also didn't call netif_start_queue() at open(), this is fixed now.

* [POWERPC] mpc5200: Allow for fixed speed MII configurationsGrant Likely2008-05-011-23/+74
| | | | | | | | | | | Various improvements for configuring the MPC5200 MII link from the device tree: * Look for 'current-speed' property for fixed speed MII links * Look for 'fsl,7-wire-mode' property for boards using the 7 wire mode * move definition of private data structure out of the header file Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfgang Grandegger <wg@grandegger.com>
* [POWERPC] mpc5200: Fix FEC error handling on FIFO errorsSascha Hauer2008-04-291-10/+13
| | | | | | | | | | | | | | | The error handling for the mpc5200 fec interrupt is broken. The intended behaviour is like this: * If one of FEC_IEVENT_RFIFO_ERROR and FEC_IEVENT_XFIFO_ERROR happens, the datasheet says (MPC5200B User's Guide R1.2, p. 14-13): "When this occurs, software must ensure both the FIFO Controller and BestComm are soft-reset". * On any other error (non-TFINT) interrupt, just issue a debug message.

| * [POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet worksRené Bürgel2008-04-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gets the FEC ethernet driver working again on the lite5200 platform. The FEC driver is also compatible with the MPC5200, not only with the MPC5200B, so this adds a suitable entry to the driver's match list. Furthermore this adds the settings for the PHY in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B. This was tested on a Lite5200 and a Lite5200B, both booted a kernel via tftp and mounted the root via nfs successfully.

* | phy: Change mii_bus id field to a stringAndy Fleming2008-04-171-1/+1
|/ | | | | | | | | | Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val).

* [POWERPC] mpc5200: normalize compatible property bindingsGrant Likely2008-01-261-4/+2Star
| | | | | | | | | | | | | | Update MPC5200 drivers to also look for compatible properties in the form "fsl,mpc5200-*" to better conform to open firmware generic names recommended practice as published here: http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html This patch should *not* break compatibility with older device trees which do not use the 'fsl,' prefix. The drivers will still bind against the older names also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
