* net: mdio: Move MDIO drivers into a new subdirectoryAndrew Lunn2020-08-271-323/+0
| | | | | | | | | | | | | | | | | Move all the MDIO drivers and multiplexers into drivers/net/mdio. The mdio core is however left in the phy directory, due to mutual dependencies between the MDIO core and the PHY core. Take this opportunity to sort the Kconfig based on the menuconfig strings, and move the multiplexers to the end with a separating comment. v2: Fix typo in commit message Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

* net: phy: Add support to configure clock in Broadcom iProc mdio muxArun Parameswaran2018-08-021-2/+39
| | | | | | | | | | | | | | | | Add support to configure the internal rate adjust register based on the core clock supplied through device tree in the Broadcom iProc mdio mux. The operating frequency of the mdio mux block is 11MHz. This is derrived by dividing the clock to the mdio mux with the rate adjust register. In some SoC's the default values of the rate adjust register do not yield 11MHz. These SoC's are required to specify the clock via the device tree for proper operation.

| | | | | | | | | | | | | | Modify the register offsets in the Broadcom iProc mdio mux to start from the top of the register address space. Earlier, the base address pointed to the end of the block's register space. The base address will now point to the start of the mdio's address space. The offsets have been fixed to match this.

* net: mdio-mux: bcm-iproc: fix wrong getter and setter pairAnton Vasilyev2018-07-291-1/+1
| | | | | | | | | | | | | mdio_mux_iproc_probe() uses platform_set_drvdata() to store md pointer in device, whereas mdio_mux_iproc_remove() restores md pointer by dev_get_platdata(&pdev->dev).

* net: mdio-mux: bcm-iproc: call mdiobus_free() in error pathJon Mason2017-05-081-1/+4
| | | | | | | | | | | | | | If an error is encountered in mdio_mux_init(), the error path will call mdiobus_free(). Since mdiobus_register() has been called prior to mdio_mux_init(), the bus->state will not be MDIOBUS_UNREGISTERED. This causes a BUG_ON() in mdiobus_free(). To correct this issue, add an error path for mdio_mux_init() which calls mdiobus_unregister() prior to mdiobus_free().

iProc based SoCs supports the integrated mdio multiplexer which has the bus selection as well as mdio transaction generation logic inside. This multiplexer has child buses for PCIe, SATA, USB and ETH. These buses could be internal or external to SOC where PHYs are attached. These buses could use C-45 or C-22 mdio transaction.
