dsa: Register netdev before phy

2016-01-07T19:31:26+00:00

When the phy is connected, an info message is printed. If the netdev
it is attached to has not been registered yet, the name
'uninitialised' in the output. By registering the netdev first, then
connecting they phy, we can avoid this.

phy: Add API for {un}registering an mdio device to a bus.

2016-01-07T19:31:26+00:00

Rather than have drivers directly manipulate the mii_bus structure,
provide and API for registering and unregistering devices on an MDIO
bus, and performing lookups.

phy: Add an mdio_device structure

2016-01-07T19:31:26+00:00

Not all devices attached to an MDIO bus are phys. So add an
mdio_device structure to represent the generic parts of an mdio
device, and place this structure into the phy_device.

phy: Centralise print about attached phy

2016-01-07T19:31:25+00:00

Many Ethernet drivers contain the same netdev_info() print statement
about the attached phy. Move it into the phy device code. Additionally
add a varargs function which can be used to append additional
information.

net: dsa: move dsa slave destroy code to slave.c

2015-12-07T21:35:50+00:00

Move dsa slave dedicated code from dsa_switch_destroy to a new
dsa_slave_destroy function in slave.c.
Add the netif_carrier_off and phy_disconnect calls in order to
correctly cleanup the netdev state and PHY state machine.

net: dsa: Add missing master netdev dev_put() calls

Upon probe failure or unbinding, add missing dev_put() calls.

net: dsa: cleanup resources upon module removal

2015-12-07T21:35:50+00:00

Make sure that we unassign the master_netdev dsa_ptr to make the packet
processing go through the regular Ethernet receive path.

net: dsa: remove DSA link polling

2015-12-07T21:35:49+00:00

Since no more DSA driver uses the polling callback, and since
the phylib handles the link detection, remove the link polling
work and timer code.

net: dsa: include gpio consumer header file

2015-11-24T16:28:06+00:00

After the introduction of the switch gpio reset API, I'm getting
build errors in configurations that disable CONFIG_GPIOLIB:

net/dsa/dsa.c:783:16: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]

The reason is that linux/gpio/consumer.h is not automatically
included without gpiolib support. This adds an explicit #include
statement to make it compile in all configurations. The reset
functionality will not work without gpiolib, which is what you
get when disabling the feature.

As far as I can tell, gpiolib is supported on all architectures
on which you can have DSA at the moment.

net: dsa: Add support for a switch reset gpio

2015-11-23T16:53:10+00:00

Some boards have a gpio line tied to the switch reset pin. Allow this
gpio to be retrieved from the device tree, and take the switch out of
reset before performing the probe.
