Fixed PHY: Add fixed_phy_change_carrier()

2018-12-17T19:24:32Z

Drivers can use this as .ndo_change_carrier() to change carrier via /sys/class/net/ethX/carrier. Signed-off-by: Joakim Tjernlund Signed-off-by: David S. Miller

net: ethernet: Convert phydev advertize and supported from u32 to link mode

2018-11-11T18:10:01Z

There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: fixed-phy: Make the error path simpler

2018-06-24T07:41:58Z

When platform_device_register_simple() fails we can return the error immediately instead of jumping to the 'err_pdev' label. This makes the error path a bit simpler. Signed-off-by: Fabio Estevam Signed-off-by: David S. Miller

net: phy: fixed-phy: remove fixed_phy_update_state()

2018-01-03T15:38:54Z

mvneta is the only user of fixed_phy_update_state(), which has been converted to use phylink instead. Remove fixed_phy_update_state(). Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phy: fixed_phy: fix of_node leak in fixed_phy_unregister

2016-11-17T17:05:05Z

Make sure to drop the of_node reference taken in fixed_phy_register() when deregistering a PHY. Fixes: a75951217472 ("net: phy: extend fixed driver with fixed_phy_register()") Signed-off-by: Johan Hovold Signed-off-by: David S. Miller

Several cases of overlapping changes, except the packet scheduler conflicts which deal with the addition of the free list parameter to qdisc_enqueue(). Signed-off-by: David S. Miller

net: phy: Manage fixed PHY address space using IDA

2016-06-29T07:51:40Z

If we have a system which uses fixed PHY devices and calls fixed_phy_register() then fixed_phy_unregister() we can exhaust the number of fixed PHYs available after a while, since we keep incrementing the variable phy_fixed_addr, but we never decrement it. This patch fixes that by converting the fixed PHY allocation to using IDA, which takes care of the allocation/dealloaction of the PHY addresses for us.

phy: improve safety of fixed-phy MII register reading

2016-06-27T14:40:57Z

There is no prevention of a concurrent call to both fixed_mdio_read() and fixed_phy_update_state(), which can result in the state being modified while it's being inspected. Fix this by using a seqcount to detect modifications, and memcpy()ing the state. We remain slightly naughty here, calling link_update() and updating the link status within the read-side loop - which would need rework of the design to change.

phy: generate swphy registers on the fly

2016-06-27T14:40:57Z

Generate software phy registers as and when requested, rather than duplicating the state in fixed_phy. This allows us to eliminate the duplicate storage of of the same data, which is only different in format. As fixed_phy_update_regs() no longer updates register state, rename it to fixed_phy_update().

phy: separate swphy state validation from register generation

2016-06-27T14:40:57Z

Separate out the generation of MII registers from the state validation. This allows us to simplify the error handing in fixed_phy() by allowing earlier error detection. Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller
