net: phy: Add support for resolving 5G and 2.5G autoneg

2018-11-11T18:10:02+00:00

Now that 2.5G and 5G can be represented in phydev->advertising and
phydev->lp_advertising, add these two links modes as possible
resolutions to auto negotiation.

net: phy: Add more link modes to the settings table

2018-11-11T18:10:01+00:00

Now that PHYs and MAC can support more than 32 bit masks, add link
modes which are > 31 to the PHY settings table.

net: phy: Convert u32 phydev->lp_advertising to linkmode

2018-11-11T18:10:01+00:00

Convert phy drivers to report the link partner advertised modes using
a linkmode bitmap. This allows them to report the higher speeds which
don't fit in a u32.

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

2018-11-11T18:10:01+00:00

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.

net: phy: Fix spelling mistake: "advertisment"-> "advertisement"

Trivial fix to spelling mistake in comments and error message text.

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 paged phy register accessors

Add a set of paged phy register accessors which are inherently safe in
their design against other accesses interfering with the paged access.

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.
