net: phy: Have __phy_modify return 0 on success

2018-01-15T17:49:30+00:00

__phy_modify would return the old value of the register before it was modified. Thus on success, it does not return 0, but a positive value. Thus functions using phy_modify, which is a wrapper around __phy_modify, can start returning > 0 on success, rather than 0. As a result, breakage has been noticed in various places, where 0 was assumed. Code inspection does not find any current location where the return of the old value is currently used. So have __phy_modify return 0 on success. When there is a real need for the old value, either a new accessor can be added, or an additional parameter passed.

net: phy: add phy_modify() accessor

Add phy_modify() convenience accessor to complement the mdiobus counterpart. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add paged phy register accessors

2018-01-03T16:00:23+00:00

Add a set of paged phy register accessors which are inherently safe in their design against other accesses interfering with the paged access. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add unlocked accessors

2018-01-03T16:00:22+00:00

Add unlocked versions of the bus accessors, which allows access to the bus with all the tracing. These accessors validate that the bus mutex is held, which is a basic requirement for all mii bus accesses. Also added is a read-modify-write unlocked accessor with the same locking requirements.

net: phy: use unlocked accessors for indirect MMD accesses

Use unlocked accessors for indirect MMD accesses to clause 22 PHYs. This permits tracing of these accesses. Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phy: add helper to convert negotiation result to phy settings

2018-01-02T20:00:50+00:00

Add a helper to convert the result of the autonegotiation advertisment into the PHYs speed and duplex settings. If the result is full duplex, also extract the pause mode settings from the link partner advertisment. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add 1000Base-X to phy settings table

2017-08-07T03:55:28+00:00

Add the missing 1000Base-X entry to the phy settings table. This was not included because the original code could not cope with more than 32 bits of link mode mask. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: move phy_lookup_setting() and guts of phy_supported_speeds() to phy-core

2017-08-07T03:55:28+00:00

phy_lookup_setting() provides useful functionality in ethtool code outside phylib. Move it to phy-core and allow it to be re-used (eg, in phylink) rather than duplicated elsewhere. Note that this supports the larger linkmode space. As we move the phy settings table, we also need to move the guts of phy_supported_speeds() as well.
