Attached is a driver for SMSC's LAN911x and LAN921x families of embedded ethernet controllers. There is an existing smc911x driver in the tree; this is intended to replace it. Dustin McIntire (the author of the smc911x driver) has expressed his support for switching to this driver. This driver contains workarounds for all known hardware issues, and has been tested on all flavours of the chip on multiple architectures. This driver now uses phylib, so this patch also adds support for the device's internal phy Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: Bahadir Balban <Bahadir.Balban@arm.com> Signed-off-by: Dustin Mcintire <dustin@sensoria.com> Signed-off-by: Bill Gatliff <bgat@billgatliff.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

All supported SMSC PHYs implement the standard "power down" bit 11 of
BMCR, so this patch adds support using the generic genphy_{suspend,resume}
functions.

Suspend/resume routines check for phydrv != NULL, but that is wrong because "phydrv" comes from container_of(drv). If drv is NULL, then container_of(drv) will return non-NULL result, and the checks won't work. The Freescale TBI PHYs are driver-less, so "drv" is NULL, and that leads to the following oops: Unable to handle kernel paging request for data at address 0xffffffe4 Faulting instruction address: 0xc0215554 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c0215554] mdio_bus_suspend+0x34/0x70 LR [c01cc508] suspend_device+0x258/0x2bc Call Trace: [cfad3da0] [cfad3db8] 0xcfad3db8 (unreliable) [cfad3db0] [c01cc508] suspend_device+0x258/0x2bc [cfad3dd0] [c01cc62c] dpm_suspend+0xc0/0x140 [cfad3e20] [c01cc6f4] device_suspend+0x48/0x5c [cfad3e40] [c0068dd8] suspend_devices_and_enter+0x8c/0x148 [cfad3e60] [c00690f8] enter_state+0x100/0x118 [cfad3e80] [c00691c0] state_store+0xb0/0xe4 [cfad3ea0] [c018c938] kobj_attr_store+0x24/0x3c [cfad3eb0] [c00ea9a8] flush_write_buffer+0x58/0x7c [cfad3ed0] [c00eadf0] sysfs_write_file+0x58/0xa0 [cfad3ef0] [c009e810] vfs_write+0xb4/0x16c [cfad3f10] [c009ed40] sys_write+0x4c/0x90 [cfad3f40] [c0014954] ret_from_syscall+0x0/0x38 [...] This patch fixes the issue, plus removes unneeded parentheses and fixes indentation level in mdio_bus_suspend().

phy: fix phy address bug
PHYID returns 0xffff and not 0xffffffff when not found and in some
case(at91sam9263) 0x0. Maybe this patch could be useful.
phy_device.c treats PHY ID == 0x0 as bogus IDs, and that results in
gianfar driver failure to see the TBI PHYs. This code snippet triggers:
if (!priv->tbiphy) {
printk(KERN_WARNING "SGMII mode requires that the device "
"tree specify a tbi-handle\n");
return;
}
Although tbi-handle is specified in the device tree.
Btw, technically PHY ID == 0x0 is a valid ID (if we ever see a PHY
manufactured by Xerox :-).

The PHYLIB mdio code has more problems in error paths: - mdiobus_release can be called before bus->state is set to MDIOBUS_REGISTERED - mdiobus_scan allocates resources which need to be freed - the comment is wrong, the resistors used are actually pull-ups.

kernel BUG at drivers/net/phy/mdio_bus.c:165!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
How?
mdiobus_alloc() sets bus->state = MDIOBUS_ALLOCATED.
mdiobus_register() sets bus->state = MDIOBUS_REGISTERED but then can
fail (mdiobus_scan()) returning an error to the caller.
The caller aborts correctly with mdiobus_free() which does:
if (bus->state == MDIOBUS_ALLOCATED) {
kfree(bus);
return;
}
BUG_ON(bus->state != MDIOBUS_UNREGISTERED);

genphy_setup_forced hasn't actually reset the PHY for a long time, but a comment to that effect remained in the code, so code continued to act as if it *had* reset the PHY, and called the necessary fixup functions to respond to a PHY reset. With no reset, those functions are no longer needed, so we remove them. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
