1d33ee019f kernel: qca-ssdk: fix C45 MDIO support on kernel 6.6
Kernel 6.3 has introduced separate C45 read/write operations, and thus
split them out of the C22 operations completely so the old way of marking
C45 reads and writes via the register value does not work anymore.

This is causing SSDK to fail and find C45 only PHY-s such as Aquantia ones:
[   22.187877] ssdk_phy_driver_init[371]:INFO:dev_id = 0, phy_adress = 8, phy_id = 0x0 phytype doesn't match
[   22.209924] ssdk_phy_driver_init[371]:INFO:dev_id = 0, phy_adress = 0, phy_id = 0x0 phytype doesn't match

This in turn causes USXGMII MAC autoneg bit to not get set and then UNIPHY
autoneg will time out, causing the 10G ports not to work:
[   37.292784] uniphy autoneg time out!

So, lets detect C45 reads and writes by the magic BIT(30) in the register
argument and if so call separate C45 mdiobus read/write functions.

d08d53346b qca-ssdk: support selecting PCS channel for PORT3 on IPQ6018
When QCA8072 is used in PSGMII mode with IPQ6018, PCS used for second
PHY port would overlap with one used by SGMII+ port. SoC has register
to select different PCS in such case.

Original code used PHY_ID for this decision, which also had other
issues, but is no longer viable since we moved to upstream QCA807x
driver.

Introduce DT property port3_pcs_channel to allow describing this in DT.
Default value is <2>, and for some QCA8072 designs <4> would be needed.

qca-ssdk: add patch to support detection of PSGMII mode for PHY
If a PHY doesn't use the integrated driver, SSDK use poll the phydev to
get the real PHY mode. qca807x use PSGMII as PHY mode and this specific
mode is not detected in qca SSDK while used in the entire driver.

Add support for it in the hsl_port_phydev_interface_mode_status_get
function used to translate PHY mode to the internal SSDK value.

qca-ssdk: fix unsupported scenario with PORT1 not declared in switch bmp
Commit 947b44d ("ipq807x: fix wrong define for LAN and WAN ess mask")
started fixing wrong switch_lan_bmp that defined lan there weren't
actually present. This displayed a fragility in the malibu phy init code
in qca-ssdk.

Add patch to fix this. Also update each DTS with the new required
property if needed.

The new binding malibu_phy_start_addr is required with devices that
place the malibu first PHY referring port1 on a different PHY addres
than 0. The most common configuration is 0 but some device (for example
Qnap 301W) place the malibu PHY at an offset to address 16.

Refer to ipq8074-ess dtsi for extensive description on how to derive
this value.

Quoting the patch detailed description:

The usage of first_phy_addr is EXTREMELY FRAGILE and results
in dangerous results if the OEM (or anyone that by chance try to
implement things in a logical manner) deviates from the default values
from the "magical template".

To be in more details. With QSDK 12.4, some tweaks were done to improve
autoneg and now on every call of port status, the phydev is tried to
add. This resulted in the call and log spam of an error with ports that
are actually not present on the system with qsdk reporting phydev is
NULL. This itself is not an error and printing the error is correct.

What is actually an error from ages is setting generic bitmap reporting
presence of port that are actually not present. This is very common on
OEM where the switch_lan_bmp is always a variant of 0x1e (that on bitmap
results in PORT1 PORT2 PORT3 PORT4 present) or 0x3e (PORT1 PORT2 PORT3
PORT4 PORT5). Reality is that many device are used as AP with one LAN
port or one WAN port. (or even exotic configuration with PORT1 not
present and PORT2 PORT3 PORT4 present (Xiaomi 3600)

With this finding one can say... ok nice, then lets update the DT and
set the correct bitmap...

Again world is a bad place and reality is that this cause wonderful
regression in some case of by extreme luck the first ever connected
port working and the rest of the switch dead.

The problem has been bisected to all the device that doesn't have the
PORT1 declared in any of the bitmap.

With this prefaction in mind, on to the REAL problem.

malibu_phy_hw_init FOR SOME REASON, set a global variable first_phy_addr
to the first detected PHY addr that coincidentally is always PORT1.
PORT1 addr is 0x0. The entire code in malibu_phy use this variable to
derive the phy addrs in some function.

Declaring a bitmap where the PORT1 is missing (or worse PORT4 the only
one connected) result in first_phy_addr set to 1 or whatever phy addr is
detected first setting wrong value all over the init stage.

To fix this, introduce a new binding malibu_first_phy_addr to manually
declare the first phy that the malibu PHY driver should use and permit
to detach it from port bmp detection. The legacy detection is kept for
compatibility reason.

I'm very confused by this and to me it's not clear the real usage of
this logic.

From what I can see the usage of this is EXTREMELY FRAGILE and results
in dangerous results if the OEM (or anyone that by chance try to

from the "magical template".

PORT1 addr is 0x0. The entire code in malibu_phy use this variable to

Declaring a bitmap where the PORT1 is missing (or worse PORT4 the only
one connected) result in first_phy_addr set to 1 or whatever phy addr is
detected first setting wrong value all over the init stage.

To fix this, just drop this variable and hardcode everything to assume
the first phy adrr is ALWAYS 0 and remove calculation and use define for
special case.

With the following change normal switch traffic is restored and ports
function is recovered.

kernel: qca-ssdk: backport support for building as kernel module
Currently, SSDK is rather special in the sense that its not being built as
a proper out of tree module at all but rather like a userspace application
and that involves a lot of make magic which unfortunately broke with make
version 4.4 and newer.

Luckily QCA finally added a way to build SSDK as an out of tree module
and it uses the kernel buildsystem which makes it compile with make 4.4
as well.
So lets backport the support for it and switch to using it.

c608f70325 kernel: add Qualcomm SSDK driver
Qualcomm SSDK is driver for Qualcomm Atheros switches and PHY-s.

It is quite complicated and used by rest of the Qualcomm SDK stack for
anything switch or PHY related.

It is required for IPQ807x support as currently, there is no better driver
for the built-in switch or UNIPHY.

So, lets add the fixed-up version that supports kernel 5.15 for use on
ipq807x target until a better driver is available.
