net: phy: fix reading fixed phy status

2019-02-25T06:29:14Z

With the switch to phy_resolve_aneg_linkmode() we don't read from the chip any longer what is advertised but use phydev->advertising directly. For a fixed phy however this bitmap is empty so far, what results in no common mode being found. This breaks DSA. Fix this by advertising everything that is supported. For a normal phy this done by phy_probe().

net: fixed-phy: Add fixed_phy_register_with_gpiod() API

2019-02-08T02:11:58Z

Add fixed_phy_register_with_gpiod() API. It lets users create a fixed_phy instance that uses a GPIO descriptor which was obtained externally e.g. through platform data. This enables platform devices (non-DT based) to use GPIOs for link status. Signed-off-by: Moritz Fischer Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: fixed_phy: Fix fixed_phy not checking GPIO

2019-02-07T17:49:49Z

Fix fixed_phy not checking GPIO if no link_update callback is registered. In the original version all users registered a link_update callback so the issue was masked.

net: phy: fixed-phy: Drop GPIO from fixed_phy_add()

2019-02-05T02:33:36Z

All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use. Tested-by: Andrew Lunn Signed-off-by: Linus Walleij Signed-off-by: David S. Miller

net: phy: Convert some PHY and MDIO driver files to SPDX headers

2019-01-23T04:53:08Z

Where the license text and the MODULE_LICENSE() value agree, convert to using an SPDX header, removing the license text. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

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
