net: xpcs: remove xpcs_config_eee() from global scope

2025-02-14T21:42:52+00:00

Make xpcs_config_eee() private to the XPCS driver, called only from
the phylink pcs_disable_eee() and pcs_enable_eee() methods.

net: xpcs: add function to configure EEE clock multiplying factor

2025-02-14T21:42:51+00:00

Add a function to separate out the EEE clock multiplying factor. This
will be called by the stmmac driver to configure this value.

It would have been better had the driver used the CLK API to retrieve
this clock, get its rate and calculate the appropriate multiplier, but
that door has closed.

2025-01-07T00:26:13+00:00

xpcs_get_interfaces() should no longer be used outside of the XPCS
code, so make it static.

net: pcs: xpcs: move definition of struct dw_xpcs to private header

2024-10-09T11:13:11+00:00

There should be no reason for anything outside the XPCS code to know
the contents of struct dw_xpcs - this is a private structure to XPCS.
Move the definition to the private pcs-xpcs.h header, leaving a
declaration in the global pcs/pcs-xpcs.h

Provide a helper to provide the pointer to the phylink_pcs struct
given a valid xpcs pointer. This will be necessary when we make
struct dw_xpcs private to pcs-xpcs.c

As nothing outside pcs-xpcs.c calls neither xpcs_do_config() nor
xpcs_link_up(), remove their exports and prototypes.

net: pcs: xpcs: drop interface argument from xpcs_create*()

2024-10-03T00:32:01+00:00

The XPCS sub-driver no longer uses the "interface" argument to the
xpcs_create_mdiodev() and xpcs_create_fwnode() functions. Remove
this now unnecessary argument, updating the stmmac driver
appropriately.

net: pcs: xpcs: add xpcs_destroy_pcs() and xpcs_create_pcs_mdiodev()

2024-10-03T00:32:00+00:00

Provide xpcs create/destroy functions that return and take a phylink_pcs
pointer instead of an xpcs pointer. This will be used by drivers that
have been converted to use phylink_pcs pointers internally, rather than
dw_xpcs pointers.

As xpcs_create_mdiodev() no longer makes use of its interface argument,
pass PHY_INTERFACE_MODE_NA into xpcs_create_mdiodev() until it is
removed later in the series.

net: pcs: xpcs: move PCS reset to .pcs_pre_config()

2024-10-03T00:31:59+00:00

Move the PCS reset to .pcs_pre_config() rather than at creation time,
which means we call the reset function with the interface that we're
actually going to be using to talk to the downstream device.

net: pcs: xpcs: Add fwnode-based descriptor creation method

2024-07-05T08:35:51+00:00

It's now possible to have the DW XPCS device defined as a standard
platform device for instance in the platform DT-file. Although that
functionality is useless unless there is a way to have the device found by
the client drivers (STMMAC/DW *MAC, NXP SJA1105 Eth Switch, etc). Provide
such ability by means of the xpcs_create_fwnode() method. It needs to be
called with the device DW XPCS fwnode instance passed. That node will be
then used to find the MDIO-device instance in order to create the DW XPCS
descriptor.

Note the method semantics and name is similar to what has been recently
introduced in the Lynx PCS driver.
