net: mdio: Move MDIO drivers into a new subdirectory

2020-08-27T13:55:50+00:00

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

net: pcs: Move XPCS into new PCS subdirectory

2020-08-27T13:55:50+00:00

Create drivers/net/pcs and move the Synopsys DesignWare XPCS into the
new directory. Move the header file into a subdirectory
include/linux/pcs

Start a naming convention of all PCS files use the prefix pcs-, and
rename the XPCS files to fit.

v2:
Add include/linux/pcs

v4:
Fix include path in stmmac.
Remove PCS_DEVICES to avoid new prompts

net: phy: add a Kconfig option for mdio_devres

2020-07-07T22:37:02+00:00

If phylib is built as a module and CONFIG_MDIO_DEVICE is 'y', the
mdio_device and mdio_bus code will be in the phylib module, not in the
kernel image. Meanwhile we build mdio_devres depending on the
CONFIG_MDIO_DEVICE symbol, so if it's 'y', it will go into the kernel
and we'll hit the following linker error:

   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_alloc_size':
>> drivers/net/phy/mdio_devres.c:38: undefined reference to `mdiobus_alloc_size'
   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_free':

   ld: drivers/net/phy/mdio_devres.o: in function `__devm_mdiobus_register':

   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_unregister':

>> drivers/net/phy/mdio_devres.c:120: undefined reference to `of_mdiobus_register'

Add a hidden Kconfig option for MDIO_DEVRES which will be currently
selected by CONFIG_PHYLIB as there are no non-phylib users of these
helpers.

of: mdio: provide devm_of_mdiobus_register()

2020-06-30T22:57:34+00:00

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.

phy: un-inline devm_mdiobus_register()

2020-06-30T22:57:34+00:00

Functions should only be static inline if they're very short. This
devres helper is already over 10 lines and it will grow soon as we'll
be improving upon its approach. Pull it into mdio_devres.c.

net: phy: add Broadcom BCM54140 support

2020-04-22T19:14:18+00:00

The Broadcom BCM54140 is a Quad SGMII/QSGMII Copper/Fiber Gigabit
Ethernet transceiver.

This also adds support for tunables to set and get downshift and
energy detect auto power-down.

The PHY has four ports and each port has its own PHY address.
There are per-port registers as well as global registers.
Unfortunately, the global registers can only be accessed by reading
and writing from/to the PHY address of the first port. Further,
there is no way to find out what port you actually are by just
reading the per-port registers. We therefore, have to scan the
bus on the PHY probe to determine the port and thus what address
we need to access the global registers.

net: phy: move the mscc driver to its own directory

2020-03-15T04:06:45+00:00

The MSCC PHY driver is growing, with lots of space consuming features
(firmware support, full initialization, MACsec...). It's becoming hard
to read and navigate in its source code. This patch moves the MSCC
driver to its own directory, without modifying anything, as a
preparation for splitting up its features into dedicated files.
