net: phy: rework Kconfig settings for MDIO_BUS

2017-07-28T00:20:19+00:00

I still see build errors in randconfig builds and have had this
patch for a while to locally work around it:

drivers/built-in.o: In function `xgene_mdio_probe':
mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register'
mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free'
mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size'

The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus
code is built-in or a module, and other drivers that use the core
code can simply depend on that, instead of having a complex
dependency line.

The conflicts were two cases of overlapping changes in
batman-adv and the qed driver.

net: phy: Fix MDIO_THUNDER dependencies

After commit 90eff9096c01 ("net: phy: Allow splitting MDIO
bus/device support from PHYs") we could create a configuration where
MDIO_DEVICE=y and PHYLIB=m which leads to the following undefined
references:

net: phy: add Marvell Alaska X 88X3310 10Gigabit PHY support

2017-06-07T01:14:13+00:00

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310).
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.

net: phy: Add Cortina CS4340 driver

2017-05-30T16:42:27+00:00

Add basic support for Cortina PHY drivers. 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.

net: phy: Allow splitting MDIO bus/device support from PHYs

2017-03-24T19:51:05+00:00

Introduce a new configuration symbol: MDIO_DEVICE which allows building
the MDIO devices and bus code, without pulling in the entire Ethernet
PHY library and devices code.

PHYLIB nows select MDIO_DEVICE and the relevant Makefile files are
updated to reflect that.

When MDIO_DEVICE (MDIO bus/device only) is selected, but not PHYLIB, we
have mdio-bus.ko as a loadable module, and it does not have a
module_exit() function because the safety of removing a bus class is
unclear.

When both MDIO_DEVICE and PHYLIB are enabled, we need to assemble
everything into a common loadable module: libphy.ko because of nasty
circular dependencies between phy.c, phy_device.c and mdio_bus.c which
are really tough to untangle.

net: phy: Add Meson GXL Internal PHY driver

2016-11-09T17:50:55+00:00

Add driver for the Internal RMII PHY found in the Amlogic Meson GXL SoCs.

This PHY seems to only implement some standard registers and need some
workarounds to provide autoneg values from vendor registers.

Some magic values are currently used to configure the PHY, and this a
temporary setup until clarification about these registers names and
registers fields are provided by Amlogic.
