net: phy: bcm63xx: Utilize correct config_intr function

2017-02-04T08:45:09Z

[ Upstream commit cd33b3e0da43522ff8e8f2b2b71d3d08298512b0 ] Commit a1cba5613edf ("net: phy: Add Broadcom phy library for common interfaces") make the BCM63xx PHY driver utilize bcm_phy_config_intr() which would appear to do the right thing, except that it does not write to the MII_BCM63XX_IR register but to MII_BCM54XX_ECR which is different. This would be causing invalid link parameters and events from being generated by the PHY interrupt.

Revert "phy: IRQ cannot be shared"

2016-09-30T08:18:37Z

[ Upstream commit c3e70edd7c2eed6acd234627a6007627f5c76e8e ] This reverts: commit 33c133cc7598 ("phy: IRQ cannot be shared") On hardware with multiple PHY devices hooked up to the same IRQ line, allow them to share it. Sergei Shtylyov says: "I'm not sure now what was the reason I concluded that the IRQ sharing was impossible... most probably I thought that the kernel IRQ handling code exited the loop over the IRQ actions once IRQ_HANDLED was returned -- which is obviously not so in reality..."

net: dp83640: Fix tx timestamp overflow handling.

2016-03-03T23:07:04Z

[ Upstream commit 81e8f2e930fe76b9814c71b9d87c30760b5eb705 ] PHY status frames are not reliable, the PHY may not be able to send them during heavy receive traffic. This overflow condition is signaled by the PHY in the next status frame, but the driver did not make use of it. Instead it always reported wrong tx timestamps to user space after an overflow happened because it assigned newly received tx timestamps to old packets in the queue. This commit fixes this issue by clearing the tx timestamp queue every time an overflow happens, so that no timestamps are delivered for overflow packets. This way time stamping will continue correctly after an overflow. Signed-off-by: Manfred Rudigier Acked-by: Richard Cochran Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

net: phy: mdio-mux: Check return value of mdiobus_alloc()

2015-12-14T19:27:40Z

mdiobus_alloc() might return NULL, but its return value is not checked in mdio_mux_init(). This could potentially lead to a NULL pointer dereference.

phy: micrel: Fix finding PHY properties in MAC node.

2015-12-12T01:31:15Z

commit 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not the bus' parent.") changed the parenting of PHY devices, making them a child of the MDIO bus, instead of the MAC device. This broken the Micrel PHY driver which has a deprecated feature of allowing PHY properties to be placed into the MAC node. In order to find the MAC node, we need to walk up the tree of devices until we find one with an OF node attached.

net: phy: reset only targeted phy

2015-12-03T20:26:13Z

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. Signed-off-by: Jérôme Pouiller Signed-off-by: David S. Miller

broadcom: fix PHY_ID_BCM5481 entry in the id table

2015-11-24T04:29:27Z

Commit fcb26ec5b18d ("broadcom: move all PHY_ID's to header") updated broadcom_tbl to use PHY_IDs, but incorrectly replaced 0x0143bca0 with PHY_ID_BCM5482 (making a duplicate entry, and completely omitting the original). Fix that. Fixes: fcb26ec5b18d ("broadcom: move all PHY_ID's to header") Signed-off-by: Aaro Koskinen Signed-off-by: David S. Miller

net: phy: Use interrupts when available in NOLINK state

2015-11-17T20:25:44Z

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. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller
