* | net: phy: mdio-bcm-unimac: Add debug print for PHY workaroundFlorian Fainelli2017-07-311-1/+3
| | | | | | | | | | | | | | | | | | In order to be stricly identical to what bcmgenet does, add a debug print when a PHY workaround during bus->reset() is executed. Preliminary change to moving bcmgenet towards mdio-bcm-unimac. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | net: phy: mdio-bcm-unimac: create unique bus namesFlorian Fainelli2017-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for having multiple GENET instances in a system (up to 3), make sure that we do include the bus instance number in the name of the MDIO bus such that we change it from "unimac-mdio" to "unimac-mdio-0" for instance. So far, the only user of this driver is using Device Tree, which uses a lookup/parenting based technique to map PHY devices to their respective MDIO bus controllers, hence causing no additional changes.

| * mdio: mux: fix parsing mux registers outside of the PHY address rangeMartin Blumenstingl2017-07-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). Fix this by reverting the change from of_mdio_parse_addr to of_mdio_parse_addr.

| * net: phy: dp83867: add workaround for incorrect RX_CTRL pin strapMurali Karicheri2017-07-051-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). There are some boards which have the pin strapped this way and need software workaround suggested by the data manual. Bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0. This ensures proper operation of the PHY. Implement driver support for device-tree property meant to advertise the wrong strapping.

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.

Support only CS4340 for now. The phys are not compatible with IEEE 802.3 clause 22/45 registers. Implement proper read_status support. The generic 10G phy driver causes bus register access errors. The driver should be described using the "ethernet-phy-id" device tree compatible.

In such a case, sysfs_create_link() would return -ENOENT because the network device's kobject is not ready yet, and we would fail to connect to the PHY device. In order to keep things simple and symetrical, we just take the success path as indicative of the ability to access the network device's kobject, and create the second link if that's the case.
