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: phy_{read|write}_mmd_indirect: get addr from phydev

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

The address of the device can be determined from the phydev structure,
rather than passing it as a parameter.

phy: Add phydev_err() and phydev_dbg() macros

2016-01-07T19:31:24+00:00

In preparation for moving some of the phy_device structure members,
add macros for printing errors and debug information.

net: phy: reset only targeted phy

2015-12-03T20:26:13+00:00

It is possible to address another chip on same MDIO bus. The case is
correctly handled for media advertising. It is taken into account
only if mii_data->phy_id == phydev->addr. However, this condition
was missing for reset case.

net: phy: Use interrupts when available in NOLINK state

2015-11-17T20:25:44+00:00

The NOLINK state will poll the phy once a second to see if the link
has come up. If the phy has an interrupt line, this polling can be
skipped, since the phy should interrupt when the link returns.

phylib: simplify NULL checks

2015-08-28T21:15:25+00:00

Fix scripts/checkpatch.pl's messages like:

CHECK: Comparison to NULL could be written "!phydrv->read_mmd_indirect"

BTW, it doesn't detect the reversed comparisons (which I've fixed as well).

net: phy: add locking to phy_read_mmd_indirect()/phy_write_mmd_indirect()

2015-08-25T23:30:46+00:00

The phy layer is missing locking for the above two functions - it
has been observed that two threads (userspace and the phy worker
thread) can race, entering the bus ->write or ->read functions
simultaneously.

This causes the FEC driver to initialise a completion while another
thread is waiting on it or while the interrupt is calling complete()
on it, which causes spinlock unlock-without-lock, spinlock lockups,
and completion timeouts.

net: phy: fix PHY_RUNNING in phy_state_machine

2015-08-17T19:18:09+00:00

Currently, if phy state is PHY_RUNNING, we always register a CHANGE
when phy works in polling or interrupt ignored, this will make the
adjust_link being called even the phy link did Not changed.

checking the phy link to make sure the link did changed before we
register a CHANGE, if link did not changed, we do nothing.
