netdev/phy: Prototype of_mdio_find_bus()

2012-10-09T17:54:59+00:00

Ensure that of_mdio_find_bus() matches the prototype in the header (and
stop sparse complaining) by including the header with the prototype.

The team, fib_frontend, route, and l2tp_netlink conflicts were simply
overlapping changes.

qmi_wwan and bat_iv_ogm were of the "use HEAD" variety.

net: phy: smsc: Implement PHY config_init for LAN87xx

2012-09-27T22:28:30+00:00

The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving
capability. Enabling it leads to the PHY not being able to detect Link when
cold-started without cable connected. Thus, make sure this is disabled.

lxt PHY: Support for the buggy LXT973 rev A2

2012-09-27T21:58:06+00:00

This patch adds proper handling of the buggy revision A2 of LXT973 phy, adding
precautions linked to ERRATA Item 4:

Revision A2 of LXT973 chip randomly returns the contents of the previous even
register when you read a odd register regularly

phy/micrel: Rename KS80xx to KSZ80xx

2012-09-24T19:54:33+00:00

There is no such part as KS8001, KS8041 or KS8051. There are only
KSZ8001, KSZ8041 and KSZ8051. Rename these parts as such to match
the Micrel naming.

phy/micrel: Implement support for KSZ8021

2012-09-24T19:54:32+00:00

The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.

ptp: link the phc device to its parent device

2012-09-22T19:42:38+00:00

PTP Hardware Clock devices appear as class devices in sysfs. This patch
changes the registration API to use the parent device, clarifying the
clock's relationship to the underlying device.

net/phy/bcm87xx: Add MODULE_LICENSE("GPL") to GPL driver

2012-09-22T19:33:46+00:00

Currently the driver has no MODULE_LICENSE attribute in its source which
results in a kernel taint if I load this:

root@(none):~# modprobe bcm87xx
bcm87xx: module license 'unspecified' taints kernel.

Since the first lines of the source code clearly state:
 * This file is subject to the terms and conditions of the GNU General
 * Public License.  See the file "COPYING" in the main directory of this
 * archive for more details.
I think it's safe to add the MODULE_LICENSE("GPL") macro and thus remove
the kernel taint.

netdev/phy: mdio-mux-mmioreg.c should include of_address.h

2012-09-07T21:32:25+00:00

mdio-mux-mmioreg.c uses function of_address_to_resource(), which is defined
in linux/of_address.h.  This fixes a compilation error:

drivers/net/phy/mdio-mux-mmioreg.c: In function 'mdio_mux_mmioreg_probe':
drivers/net/phy/mdio-mux-mmioreg.c:83:2: error: implicit declaration of

netdev/phy: add MDIO bus multiplexer driven by a memory-mapped device

2012-08-30T16:54:48+00:00

Add support for an MDIO bus multiplexer controlled by a simple memory-mapped
device, like an FPGA.  The device must be memory-mapped and contain only
8-bit registers (which keeps things simple).

Tested on a Freescale P5020DS board which uses the "PIXIS" FPGA attached
to the localbus.
