of: mdio: fixup of_phy_register_fixed_link parsing of new bindings

2014-06-23T04:35:14+00:00

Fixes commit 3be2a49e5c08 ("of: provide a binding for fixed link PHYs")

Fix the parsing of the new fixed link dts bindings for duplex,
pause, and asym_pause by using the correct device node pointer.

of_get_property() can be called with NULL as 2nd argument if the caller
is not interested in the length of a property. Use that here so we can
get rid of a variable.

net: of_mdio: add of_mdiobus_link_phydev()

2014-05-29T22:23:29+00:00

Add a function to walk the list of subnodes of a mdio bus and look for
a node that matches the phy's address with its 'reg' property. If found,
set the of_node pointer for the phy. This allows auto-probed pyh
devices to be augmented by information passed in via DT.

Factor out some logic into of_mdio_parse_addr() so it can be reused
later. While at it, use of_property_read_u32() rather than open-coding
the same logic again.

Commit de906af1 (net: phy: make of_set_phy_supported work with genphy driver)
removed the last user of variable 'max_speed' in function
of_mdiobus_register_phy(), leading to compile warning "unused variable
‘max_speed’ [-Wunused-variable]". Thus remove it.

net: phy: make of_set_phy_supported work with genphy driver

2014-05-22T19:43:02+00:00

of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. of_set_phy_supported is
called right after phy_device_register in the assumption that
phy_probe is called from phy_device_register and the features
of the phy are already initialized. For the genphy driver this
is not true, here phy_probe is called later during phy_connect
time. phy_probe will then overwrite all settings done from
of_set_phy_supported
Fix this by moving of_set_phy_supported to the core phy code
and calling it from phy_probe.

All in-tree drivers have been converted to use the new pair of

can now safely remove of_phy_connect_fixed_link.

of: provide a binding for fixed link PHYs

2014-05-16T21:19:22+00:00

Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.

This patch adds:

 * A documentation for the fixed PHY Device Tree binding.

 * An of_phy_is_fixed_link() function that an Ethernet driver can call
   on its PHY phandle to find out whether it's a fixed link PHY or
   not. It should typically be used to know if
   of_phy_register_fixed_link() should be called.

 * An of_phy_register_fixed_link() function that instantiates the
   fixed PHY into the PHY subsystem, so that when the driver calls
   of_phy_connect(), the PHY device associated to the OF node will be
   found.

These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.
