net: phy: micrel: fix KSZ8041FTL supported value

2016-11-24T01:18:36+00:00

Fix setting of SUPPORTED_FIBRE bit as it was not present in features
of KSZ8041.

phy: micrel.c: Enable ksz9031 energy-detect power-down mode

2016-10-06T01:19:06+00:00

Set bit 0 in register 1C.23 to enable the EDPD feature of the
KSZ9031 PHY. This reduces power consumption when the link is
down.

phy: micrel: Reenable interrupts during resume for ksz9031

2016-08-23T23:56:54+00:00

Like the ksz8081, the ksz9031 has the behavior where it will clear the
interrupt enable bits when leaving power down. This takes advantage of the
solution provided by f5aba91.

net: phy: micrel: Add specific suspend

2016-08-09T23:19:15+00:00

Disable all interrupts when suspend, they will be enabled
when resume. Otherwise, the suspend/resume process will be
blocked occasionally.

phy/micrel: Change phy_id_mask for KSZ8721

2016-08-01T03:37:12+00:00

There are KSZ8721 PHYs with phy_id 0x00221619. In order to detect them
as PHY_ID_KSZ8001 compatible while staying different to PHY_ID_KSZ9021
ignore the last two bits when matching PHY_ID

net: phy: micrel: Add KSZ8041FTL fiber mode support

2016-07-15T18:53:02+00:00

We can't detect the FXEN (fiber mode) bootstrap pin, so configure
it via a boolean device tree property "micrel,fiber-mode".
If it is enabled, auto-negotiation is not supported.
The only available modes are 100base-fx (full duplex and half duplex).

phy: micrel: Use MICREL_PHY_ID_MASK definition

2016-05-12T20:55:33+00:00

Replace the hardcoded mask 0x00fffff0 with MICREL_PHY_ID_MASK for
better readability.

phy: micrel: Disable auto negotiation on startup

2016-03-01T21:52:09+00:00

Disable auto negotiation on init to properly detect an already plugged
cable at boot.

At boot, when the phy is started, it is in the PHY_UP state.
However, if a cable is plugged at boot, because auto negociation is already
enabled at the time we get the first interrupt, the phy is already running.
But the state machine then switches from PHY_UP to PHY_AN and calls
phy_start_aneg(). phy_start_aneg() will not do anything because aneg is
already enabled on the phy. It will then wait for a interrupt before going
further. This interrupt will never happen unless the cable is unplugged and
then replugged.

It was working properly before 321beec5047a (net: phy: Use interrupts when
available in NOLINK state) because switching to NOLINK meant starting
polling the phy, even if IRQ were enabled.

phy: micrel: Ensure interrupts are reenabled on resume

2016-03-01T21:52:08+00:00

At least on ksz8081, when getting back from power down, interrupts are
disabled. ensure they are reenabled if they were previously enabled.

This fixes resuming which is failing on the xplained boards from atmel
since 321beec5047a (net: phy: Use interrupts when available in NOLINK
state)
