Anton Vorontsov c8f15686a4 netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328
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.

They logically all want to trigger a schedule for all device

Grant Likely 80791be111 [POWERPC] mpc5200: Allow for fixed speed MII configurations
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

Sascha Hauer 8f3ba2dc81 [POWERPC] mpc5200: Fix FEC error handling on FIFO errors
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.

Andy Fleming 9d9326d3bc phy: Change mii_bus id field to a string
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).

René Bürgel 8d813941b1 [POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet works
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.

Grant Likely 66ffbe490b [POWERPC] mpc5200: normalize compatible property bindings
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.
