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.

phy: move fixed_phy MII register generation to a library

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

Move the fixed_phy MII register generation to a library to allow other software phy implementations to use this code. Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller
