The sja1105 hardware has a quirk in that some changes require a switch
reset, which loses all configuration. When the reset is initiated,
everything needs to be reprogrammed, including the MACs and the PCS.
This is currently done in sja1105_static_config_reload() - we manually
call sja1105_adjust_port_config(), sja1105_sgmii_pcs_config() and
sja1105_sgmii_pcs_force_speed() which are all internal functions.
There is a desire for sja1105 to use the common xpcs driver, and that
means that the equivalents of those functions, xpcs_do_config() and
xpcs_link_up() respectively, will no longer be local functions.
Forcing phylink to retrigger a resolve somehow, say by doing dev_close()
followed by dev_open() is not really an option, because the CPU port
might have a PCS as well, and there is no net device which we can close
and reopen for that. Additionally, the dev_close/dev_open sequence might
force a renegotiation of the copper-side link for SGMII ports connected
to a PHY, and this is undesirable as well, because the switch reset is
much quicker than a PHY autoneg, so we would have a lot more downtime.
The only solution I see is for the sja1105 driver to keep doing what
it's doing, and that means we need to export the equivalents from xpcs
for sja1105_sgmii_pcs_config and sja1105_sgmii_pcs_force_speed, and call
them directly in sja1105_static_config_reload(). This will be done
during the conversion patch.

The NXP SJA1110 switch integrates its own, non-Synopsys PMA, but it
manages it through the register space of the XPCS itself, in a small
register window inside MDIO_MMD_VEND2 from address 0x8030 to 0x806e.
This coincides with where the registers for the default Synopsys PMA
are, but the register definitions are of course not the same.
This situation is an odd hardware quirk, but the simplest way to manage
it is to drive the SJA1110's PMA from within the XPCS driver.

The NXP SJA1105 DSA switch integrates a Synopsys SGMII XPCS on port 4.
The generic code works fine, except there is an integration issue which
needs to be dealt with: in this switch, the XPCS is integrated with a
PMA that has the TX lane polarity inverted by default (PLUS is MINUS,
MINUS is PLUS).
To obtain normal non-inverted behavior, the TX lane polarity must be
inverted in the PCS, via the DIGITAL_CONTROL_2 register.
We introduce a pma_config() method in xpcs_compat which is called by the
phylink_pcs_config() implementation.
Also, the NXP SJA1105 returns all zeroes in the PHY ID registers 2 and 3.
We need to hack up an ad-hoc PHY ID (OUI is zero, device ID is 1) in
order for the XPCS driver to recognize it. This PHY ID is added to the
public include/linux/pcs/pcs-xpcs.h for that reason (for the sja1105
driver to be able to use it in a later patch).

xpcs_get_id() searches multiple MMDs for a known PHY ID, starting with
MDIO_MMD_PCS (3). However not all integrators might have implemented
that MMD on their MDIO bus. For example, the NXP SJA1105 and SJA1110
switches only implement vendor-specific MMD 1 and 2.
When there is nothing on an MDIO bus at a certain address, traditionally
the bus returns 0xffff, which means that the bus remained in its default
pull-up state for the duration of the MDIO transaction. The 0xffff value
is widely used in drivers/net/phy/phy_device.c (see get_phy_c22_id for
example) to denote a missing device.
So it makes sense for the xpcs to ignore this value as well, and
continue its search, eventually finding the proper PHY ID in the
vendor-specific MMDs.

Vendors which integrate the Designware XPCS might modify a few things
here and there, and to support those, it's best to create separate C
files in order to not clutter up the main pcs-xpcs.c.
Because the vendor files might want to access the common xpcs registers
too, let's move them in a header file which is local to this driver and
can be included by vendor files as appropriate.

Since all the remaining members of struct mdio_xpcs_ops have direct
equivalents in struct phylink_pcs_ops, it is about time we remove it
altogether.
Since the phylink ops return void, we need to remove the error
propagation from the various xpcs methods and simply print an error
message where appropriate.
Since xpcs_get_state_c73() detects link faults and attempts to reset the
link on its own by calling xpcs_config(), but xpcs_config() now has a
lot of phylink arguments which are not needed and cannot be simply
fabricated by anybody else except phylink, the actual implementation has
been moved into a smaller xpcs_do_config().
The const struct mdio_xpcs_ops *priv->hw->xpcs has been removed, so we
need to look at the struct mdio_xpcs_args pointer now as an indication
whether the port has an XPCS or not.

Unify the 2 existing PCS drivers (lynx and xpcs) by doing a similar
thing on probe, which is to have a *_create function that takes a
struct mdio_device * given by the caller, and builds a private PCS
structure around that.
This changes stmmac to hold only a pointer to the xpcs, as opposed to
the full structure. This will be used in the next patch when struct
mdio_xpcs_ops is removed. Currently a pointer to struct mdio_xpcs_ops
is used as a shorthand to determine whether the port has an XPCS or not.
We can do the same now with the mdio_xpcs_args pointer.

Calling a function pointer with a single implementation through
struct mdio_xpcs_ops is clunky, and the stmmac_do_callback system forces
this to return int, even though it always returns zero.
Simply remove the "validate" function pointer from struct mdio_xpcs_ops
and replace it with an exported xpcs_validate symbol which is called
directly by stmmac.

The operating mode of the driver is currently to populate its
struct mdio_xpcs_args::supported and struct mdio_xpcs_args::an_mode
statically in xpcs_probe(), based on the passed phy_interface_t,
and work with those.
However this is not the operation that phylink expects from a PCS
driver, because the port might be attached to an SFP cage that triggers
changes of the phy_interface_t dynamically as one SFP module is
unpluggged and another is plugged.
To migrate towards that model, the struct mdio_xpcs_args should not
cache anything related to the phy_interface_t, but just look up the
statically defined, const struct xpcs_compat structure corresponding to
the detected PCS OUI/model number.
So we delete the "supported" and "an_mode" members of struct
mdio_xpcs_args, and add the "id" structure there (since the ID is not
expected to change at runtime).
Since xpcs->supported is used deep in the code in _xpcs_config_aneg_c73(),
we need to modify some function headers to pass the xpcs_compat from all
callers. In turn, the xpcs_compat is always supplied externally to the
xpcs module:
- Most of the time by phylink
- In xpcs_probe() it is needed because xpcs_soft_reset() writes to
MDIO_MMD_PCS or to MDIO_MMD_VEND2 depending on whether an_mode is clause
37 or clause 73. In order to not introduce functional changes related
to when the soft reset is issued, we continue to require the initial
phy_interface_t argument to be passed to xpcs_probe() so we can pass
this on to xpcs_soft_reset().
- stmmac_open() wants to know whether to call stmmac_init_phy() or not,
and for that it looks inside xpcs->an_mode, because the clause 73
(backplane) AN modes supposedly do not have a PHY. Because we moved
an_mode outside of struct mdio_xpcs_args, this is now no longer
directly possible, so we introduce a helper function xpcs_get_an_mode()
which protects the data encapsulation of the xpcs module and requires
a phy_interface_t to be passed as argument. This function can look up
the appropriate compat based on the phy_interface_t.

The xpcs driver has an apparently inadequate structure for the actual
hardware it drives.
These defines and the xpcs_probe() function would suggest that there is
one PHY ID per supported PHY interface type, and the driver simply
validates whether the mode it should operate in (the argument of
xpcs_probe) matches what the hardware is capable of:
#define SYNOPSYS_XPCS_USXGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_10GKR_ID 0x7996ced0
#define SYNOPSYS_XPCS_XLGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_SGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_MASK 0xffffffff
but that is not the case, because upon closer inspection, all the above
4 PHY ID definitions are in fact equal.
So it is the same XPCS that is compatible with all 4 sets of PHY
interface types.
This change introduces an array of struct xpcs_compat which is populated
by the single struct xpcs_id instance. It also eliminates the bogus
defines for multiple Synopsys XPCS PHY IDs and replaces them with a
single XPCS_ID, which better reflects the way in which the hardware
operates.
Because we are touching this area of the code anyway, the new array of
struct xpcs_compat, as well as the array of xpcs_id, have been moved
towards the end of the file, since they are variable declarations not
definitions. If whichever of struct xpcs_compat or struct xpcs_id need
to gain a function pointer member in the future, it is easier to
reference functions (no forward declarations needed) if we have the
const variable declarations at the end of the file.

PHYLIB being a module leads to MDIO_BUS being a module as well while the
XPCS is still built-in. What should happen in this configuration is that
PCS_XPCS should be forced to build as module. However, that select only
acts in the opposite way so we should turn it into a depends.
Fix this up by explicitly depending on MDIO_BUS.

Add support in the Lynx PCS module for the 10GBASE-R mode which is only
used to get the link state, since it offers a single fixed speed.

Add a Lynx PCS module which exposes the necessary operations to drive
the PCS using phylink.
The majority of the code is extracted from the Felix DSA driver, which
will be also modified in a later patch, and exposed as a separate module
for code reusability purposes.
As such, this aims at feature and bug parity with the existing Felix DSA
driver, and thus USXGMII, SGMII, QSGMII and 2500Base-X (only w/o in-band
AN) are supported by the Lynx PCS module since these were also supported
by Felix.
The module can only be enabled by the drivers in need and not user
selectable.
