net: phy: fix phy_start to consider PHY_IGNORE_INTERRUPT

2018-03-11T15:21:32+00:00

[ Upstream commit 08f5138512180a479ce6b9d23b825c9f4cd3be77 ]

This condition wasn't adjusted when PHY_IGNORE_INTERRUPT (-2) was added
long ago. In case of PHY_IGNORE_INTERRUPT the MAC interrupt indicates
also PHY state changes and we should do what the symbol says.

mdio-sun4i: Fix a memory leak

2018-03-03T09:23:27+00:00

[ Upstream commit 56c0290202ab94a2f2780c449395d4ae8495fab4 ]

If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.

net: phy: xgene: disable clk on error paths

[ Upstream commit ab14436065c8066c265540312742390d6d07ddd2 ]

There are several error paths in xgene_mdio_probe(),
where clk is left undisabled. The patch fixes them.

net: phy: micrel: ksz9031: reconfigure autoneg after phy autoneg workaround

2018-01-02T19:35:13+00:00

[ Upstream commit c1a8d0a3accf64a014d605e6806ce05d1c17adf1 ]

Under some circumstances driver will perform PHY reset in
ksz9031_read_status() to fix autoneg failure case (idle error count =
0xFF). When this happens ksz9031 will not detect link status change any
more when connecting to Netgear 1G switch (link can be recovered sometimes by
restarting netdevice "ifconfig down up"). Reproduced with TI am572x board
equipped with ksz9031 PHY while connecting to Netgear 1G switch.

Fix the issue by reconfiguring autonegotiation after PHY reset in
ksz9031_read_status().

net: phy: dp83867: Recover from "port mirroring" N/A MODE4

2017-11-08T09:08:35+00:00

[ Upstream commit ac6e058b75be71208e98a5808453aae9a17be480 ]

The DP83867 when not properly bootstrapped - especially with LED_0 pin -
can enter N/A MODE4 for "port mirroring" feature.

To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).

To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.

Thorough explanation of the problem can be found at following e2e thread:
"DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) -
Linux driver"

To clear Speed Selection in MDIO control register(0x10),
ie, clear bits 6 and 13 to zero while keeping other bits same.
Before AND operation,The Mask value has to be perform with bitwise NOT
operation (ie, ~ operator)

This patch clears current speed selection before writing the
new speed settings to gmii2rgmii converter
