net: phy: swphy: emulate register MII_ESTATUS

2019-08-15T18:43:48+00:00

When the genphy driver binds to a swphy it will call genphy_read_abilites that will try to read MII_ESTATUS if BMSR_ESTATEN is set in MII_BMSR. So far this would read the default value 0xffff and 1000FD and 1000HD are reported as supported just by chance. Better add explicit support for emulating MII_ESTATUS.

net: phy: improve auto-neg emulation in swphy

2019-02-25T06:28:15+00:00

Auto-neg emulation currently doesn't set bit BMCR_ANENABLE in BMCR, add this. Users will ignore speed and duplex settings in BMCR because we're emulating auto-neg, therefore we can remove related code. See also following discussion [0].

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

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

phy: generate swphy registers on the fly

2016-06-27T14:40:57+00:00

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

2016-06-27T14:40:57+00:00

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

phy: convert swphy register generation to tabular form

2016-06-27T14:40:57+00:00

Convert the swphy register generation to tabular form which allows us to eliminate multiple switch() statements. This results in a smaller object code size, more efficient, and easier to add support for faster speeds.
