Anton Vorontsov eedbc705f9 fs_enet: Revive fixed link support
Since commit aa73832c5a ("Rework
fs_enet driver to use of_mdio infrastructure") the fixed-link support
is broken in the fs_enet driver.

This patch fixes the support by removing a check for phy_node, and adding
a call to of_phy_connect_fixed_link().

Also set netdev parent device via SET_NETDEV_DEV() call, this is needed
so that OF MDIO core could find a node pointer for a device.

Plus, fix "if (IS_ERR(phydev))" check, in case of errors,
of_phy_connect() returns NULL, not ERR_PTR as phy_connect().

Wolfgang Denk 652f6787c0 fs_enet/mii-fec.c: fix MII speed calculation
The MII speed calculation was based on the CPU clock (ppc_proc_freq),
but for MPC512x we must use the bus clock instead.

This patch makes it use the correct clock and makes sure we don't
clobber reserved bits in the MII_SPEED register.

Following the removal of the unused struct net_device * parameter from

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.

Julia Lawall 4ecc8c066f drivers/net/fs_enet: remove null pointer dereference
The following code appears in the function fs_init_instance in the file drivers/net/fs_enet/fs_enet-main.c.

	if (fep->ops == NULL) {
		printk(KERN_ERR DRV_MODULE_NAME
		       ": %s No matching ops found (%d).\n",
		       ndev->name, fpi->fs_no);
		err = -EINVAL;
		goto err;
	}

This code implies that at the point of err, fep->ops can be NULL, so an
extra test is needed before dereferencing this value.

This problem was found using the following semantic match
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>

expression E, E1;

Otherwise some symbols remain undefined. Additionally, fs_enet uses
libphy, so add a select PHYLIB.

Scott Wood f860f49ee2 fs_enet: Update for API changes
This driver was recently broken by several changes for which this
driver was not (or was improperly) updated:

1. SET_MODULE_OWNER() was removed.
2. netif_napi_add() was only being called when building with
the old CPM binding.
3. The received/budget test was backwards.
4. to_net_dev() was wrong -- the device struct embedded in
the net_device struct is not the same as the of_platform
device in the private struct.
5. napi_disable/napi_enable was being called even when napi
was not being used.

These changes have been fixed, and napi is now on by default.

Scott Wood 976de6a8c3 fs_enet: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.
The existing OF glue code was crufty and broken.  Rather than fix it, it
will be removed, and the ethernet driver now talks to the device tree
directly.

The old, non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM
platforms are dropped from arch/ppc (which will hopefully be soon), and
existing arch/powerpc boards that I wasn't able to test on for this
patchset get converted (which should be even sooner).

Scott Wood 0d0d9c150c fs_enet: Align receive buffers.
At least some hardware driven by this driver needs receive buffers
to be aligned on a 16-byte boundary.  This usually happens by chance,
but it breaks if slab debugging is enabled.
