generic: 6.1: initial backport of at803x PHY driver cleanup

Browse Source 
Initial backport of at803x PHY driver cleanup. This is in preparation
for split and addition of new PHY Family based on at803x needed for
ipq807x and other IPQ Series SoC.

Other affected patch are automatically refreshed with
make target/linux/refresh

Subject: [PATCH] net: mdio: Add dedicated C45 API to MDIO bus drivers
Currently C22 and C45 transactions are mixed over a combined API calls
which make use of a special bit in the reg address to indicate if a
C45 transaction should be performed. This makes it impossible to know
if the bus driver actually supports C45. Additionally, many C22 only
drivers don't return -EOPNOTSUPP when asked to perform a C45
transaction, they mistaking perform a C22 transaction.
This is the first step to cleanly separate C22 from C45. To maintain
backwards compatibility until all drivers which are capable of
performing C45 are converted to this new API, the helper functions
will fall back to the older API if the new API is not
supported. Eventually this fallback will be removed.

Subject: [PATCH] net: phy: Introduce PSGMII PHY interface mode
The PSGMII interface is similar to QSGMII. The main difference
is that the PSGMII interface combines five SGMII lines into a
single link while in QSGMII only four lines are combined.
Similarly to the QSGMII, this interface mode might also needs
special handling within the MAC driver.
It is commonly used by Qualcomm with their QCA807x PHY series and
modern WiSoC-s.
Add definitions for the PHY layer to allow to express this type
of connection between the MAC and PHY.

Subject: [PATCH 3/6] net: phy: at803x: enable qca8081 slave seed conditionally
qca8081 is the single port PHY, the slave prefer mode is used
by default.
if the phy master perfer mode is configured, the slave seed
configuration should not be enabled, since the slave seed
enablement is for making PHY linked as slave mode easily.
disable slave seed if the master mode is preferred.

Subject: [PATCH 04/13] net: phy: at803x: move qca83xx specific check in
dedicated functions
Rework qca83xx specific check to dedicated function to tidy things up
and drop useless phy_id check.
Also drop an useless link_change_notify for QCA8337 as it did nothing an
returned early.

Subject: [PATCH 08/13] net: phy: at803x: move specific at8031 WOL bits to
dedicated function
Move specific at8031 WOL enable/disable to dedicated function to make
at803x_set_wol more generic.
This is needed in preparation for PHY driver split as qca8081 share the
same function to toggle WOL settings.
In this new implementation WOL module in at8031 is enabled after the
generic interrupt is setup. This should not cause any problem as the
WOL_INT has a separate implementation and only relay on MAC bits.

Subject: [PATCH 09/13] net: phy: at803x: move specific at8031 config_intr to
dedicated function
Move specific at8031 config_intr bits to dedicated function to make
at803x_config_initr more generic.
This is needed in preparation for PHY driver split as qca8081 share the
same function to setup interrupts.

Subject: [PATCH 12/13] net: phy: at803x: move at8035 specific DT parse to
dedicated probe
Move at8035 specific DT parse for clock out frequency to dedicated probe
to make at803x probe function more generic.
This is to tidy code and no behaviour change are intended.
Detection logic is changed, we check if the clk 25m mask is set and if
it's not zero, we assume the qca,clk-out-frequency property is set.
The property is checked in the generic at803x_parse_dt called by
at803x_probe.

Subject: [PATCH 13/13] net: phy: at803x: drop specific PHY ID check from cable
test functions
Drop specific PHY ID check for cable test functions for at803x. This is
done to make functions more generic. While at it better describe what
the functions does by using more symbolic function names.
PHYs that requires to set additional reg are moved to specific function
calling the more generic one.
cdt_start and cdt_wait_for_completion are changed to take an additional
arg to pass specific values specific to the PHY.

Subject: [PATCH 2/2] net: phy: at803x: make read specific status function more
generic
Rework read specific status function to be more generic. The function
apply different speed mask based on the PHY ID. Make it more generic by
adding an additional arg to pass the specific speed (ss) mask and use
the provided mask to parse the speed value.
This is needed to permit an easier deatch of qca808x code from the
at803x driver.

Subject: [PATCH] net: phy: at803x: better align function varibles to open
parenthesis
Better align function variables to open parenthesis as suggested by
checkpatch script for qca808x function to make code cleaner.
For cable_test_get_status function some additional rework was needed to
handle too long functions.

Generalize cable test fault length function since they all base on the
same magic values (already reverse engineered to understand the meaning
of it) to have consistenct values on every PHY.

Refactor qca808x cable test get status function to remove code
duplication and clean things up.
The same logic is applied to each pair hence it can be generalized and
moved to a common function.

QCA808x PHY Family supports Cable Diagnostic Test also for Cross Pair
Short.
Add all the define to make enable and support these additional tests.
Cross Short test was previously disabled by default, this is now changed
and enabled by default. In this mode, the mask changed a bit and length
is shifted based on the fault condition.

From c34d9452d4e5d98a655d7b625e85466320885416 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/4] net: phy: at803x: make read_status more generic
Make read_status more generic in preparation on moving it to shared
library as other PHY Family Driver will have the exact same
implementation.
The only specific part was a check for AR8031/33 if 1000basex was used.
The check is moved to a dedicated function specific for those PHYs.
