* | net: phy: export phy_start_machine() for phylinkRussell King2017-08-06
| | | | | | | | | | | | | | | | | | | | phylink will need phy_start_machine exported, so lets export it as a GPL symbol. Documentation/networking/phy.txt indicates that this should be a PHY API function.

* | net: phy: provide a hook for link up/link down eventsRussell King2017-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, we need to do additional work between the PHY coming up and marking the carrier present - for example, we may need to wait for the PHY to MAC link to finish negotiation. This changes phylib to provide a notification function pointer which avoids the built-in netif_carrier_on() and netif_carrier_off() functions. Standard ->adjust_link functionality is provided by hooking a helper into the new ->phy_link_change method.

* | net: phy: move phy_lookup_setting() and guts of phy_supported_speeds() to ↵Russell King2017-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | phy-core 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.

Fix this with a synchronous call to phy_state_machine() in order to have the state machine actually act on PHY_HALTED, set the PHY device's link down, turn the network device's carrier off and finally call the adjust_link() function.

| * mdio: mux: fix parsing mux registers outside of the PHY address rangeMartin Blumenstingl2017-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mdio_mux_init parses the child nodes of the MDIO mux. When using "mdio-mux-mmioreg" the child nodes are describing the register value that is written to switch between the MDIO busses. The change which makes the error messages more verbose changed the parsing of the "reg" property from a simple of_property_read_u32 call to of_mdio_parse_addr. On a Khadas VIM (based on the Meson GXL SoC, which uses mdio-mux-mmioreg) this prevents registering the MDIO mux (because the "reg" values on the MDIO mux child nodes are 0x2009087f and 0xe40908ff) and leads to the following errors: mdio-mux-mmioreg c883455c.eth-phy-mux: /soc/periphs@c8834000/eth-phy-mux/mdio@e40908ff PHY address -469169921 is too large mdio-mux-mmioreg c883455c.eth-phy-mux: Error: Failed to find reg for child /soc/periphs@c8834000/eth-phy-mux/mdio@e40908ff mdio-mux-mmioreg c883455c.eth-phy-mux: /soc/periphs@c8834000/eth-phy-mux/mdio@2009087f PHY address 537462911 is too large mdio-mux-mmioreg c883455c.eth-phy-mux: Error: Failed to find reg for child /soc/periphs@c8834000/eth-phy-mux/mdio@2009087f mdio-mux-mmioreg c883455c.eth-phy-mux: Error: No acceptable child buses found mdio-mux-mmioreg c883455c.eth-phy-mux: failed to register mdio-mux bus /soc/periphs@c8834000/eth-phy-mux (as a result of that ethernet is not working, because the PHY which is connected through the mux' child MDIO bus, which is not being registered).

This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only supports Clause 45 accesses. The PHY appears (based on the vendor IDs) to be two different vendors IP, with each devad containing several instances. This PHY driver has only been tested with the RJ45 copper port, fiber port and a Marvell Armada 8040-based ethernet interface. It should be noted that to use the full range of speeds, MAC drivers need to also reconfigure the link mode as per phydev->interface, since the PHY automatically changes its interface mode depending on the negotiated speed.

Clause 45 PHYs may implement the Clause 22 register set along with the Clause 22 extension MMD. Hence, we can't simply block access to the Clause 22 functions based on the PHY being a Clause 45 PHY.
