This patch
- makes mdio_device.c part of libphy
- makes mdio_device_(un)register_reset() static
- moves mdiobus_(un)register_device() from mdio_bus.c to mdio_device.c,
stops exporting both functions and makes them private to phylib
This further decouples the MDIO consumer functionality from libphy.
Note: This makes MDIO driver registration part of phylib, therefore
adjust Kconfig dependencies where needed.

As established in the previous commit, using SPEED_1000 and SPEED_2500
does not make sense for a SerDes due to the PCS encoding that is used
over the SerDes link, which inflates the data rate at the SerDes. Thus,
the use of these constants in a SerDes driver is incorrect.
Since qcom-sgmii-eth no longer implements phy_set_speed(), but instead
uses the PHY interface mode passed via the .set_mode() method, convert
the driver to use the PHY interface mode internally to decide whether
to configure the SerDes for 1.25Gbps or 3.125Gbps mode.

Now that the qcom-ethqos driver has migrated to use phy_set_mode_ext()
rather than phy_set_speed() to configure the SerDes, the support for
phy_set_speed() is now obsolete. Remove support for this method.
Using the MAC speed for the SerDes is never correct due to the PCS
encoding. For SGMII and 2500BASE-X, the PCS uses 8B10B encoding, and
so:
MAC rate * PCS output bits / PCS input bits = SerDes rate
1000M * 10 / 8 = 1250M
2500M * 10 / 8 = 3125M

qcom-sgmii-eth is an Ethernet SerDes supporting only Ethernet mode
using SGMII, 1000BASE-X and 2500BASE-X.
Add an implementation of the .set_mode() method, which can be used
instead of or as well as the .set_speed() method. The Ethernet
interface modes mentioned above all have a fixed data rate, so
setting the mode is sufficient to fully specify the operating
parameters.
Add an implementation of the .validate() method, which will be
necessary to allow discovery of the SerDes capabilities for platform

The blamed commit introduced support for specifying individual lanes as
OF nodes in the device, and these can have status = "disabled".
When that happens, for_each_available_child_of_node() skips them and
lynx_28g_probe_lane() -> devm_phy_create() is not called, so lane->phy
will be NULL. Yet it will be dereferenced in lynx_28g_cdr_lock_check(),
resulting in a crash.
This used to be well handled in v3 of that patch:
https://lore.kernel.org/linux-phy/20250926180505.760089-14-vladimir.oltean@nxp.com/
but until v5 was merged, the logic to support per-lane OF nodes was
split into a separate change, and the per-SoC compatible strings patch
was deferred to a "part 2" set. The splitting was done improperly, and
that handling of NULL lane->phy pointers was not integrated into the
proper commit.

Geert reports that enabling CONFIG_KUNIT_ALL_TESTS shouldn't enable
features that aren't enabled without it. That isn't what "*all* tests"
means, but as the prompt puts it, "All KUnit tests with satisfied
dependencies".
The impact is that enabling CONFIG_KUNIT_ALL_TESTS brings features which
cannot be disabled as built-in into the kernel.
Keep the pattern where consumer drivers have to "select PHY_COMMON_PROPS",
but if KUNIT_ALL_TESTS is enabled, also make PHY_COMMON_PROPS user
selectable, so it can be turned off.
Modify PHY_COMMON_PROPS_TEST to depend on PHY_COMMON_PROPS rather than
select it.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The divider_round_rate() function is now deprecated, so let's migrate
to divider_determine_rate() instead so that this deprecated API can be
removed.
Note that when the main function itself was migrated to use
determine_rate, this was mistakenly converted to:
req->rate = divider_round_rate(...)
This is invalid in the case when an error occurs since it can set the
rate to a negative value.

In preparation to support the FRL operation mode which gets configured
via the lanes and rate per lane tuple, switch to a driver specific
struct for configuring the link rate and bpc.
This simplifies and optimizes the implementation by allowing implicit

of the active PHY mode followed by recalculations of the link rate when
operating in FRL mode.

The problem with the current implementation is that it does not consider
that the USB controller can have multiple PHY handles with different
arguments count, as for example we have in our cn9131 based platform:
"phys = <&cp0_comphy1 0>, <&cp0_utmi0>;".
In such case calling "of_usb_get_dr_mode_by_phy" with -1 (no phy-cells)
leads to not proper phy detection, taking the "marvell,cp110-utmi-phy"
dts definition we can call the "of_usb_get_dr_mode_by_phy" with 0
(#phy-cells = <0>) and safely look for that phy.

This is to resolve the problem of wakeup system by USB3 device insertion
if HSIOMIX on, in that case, the USB3 device detects RX term on so the
USB3 device doesn't downgrade to high-speed, we can't expect CONN wakeup
(for USB3) happen because the 24MHz OSC is required ON to trigger it.
Because the device works at Super-speed so DP/DM wakeup can't happen
either. Then the entire systen can't be waken up by such device attach
event.
With this override bit we can force the RX term off when enters system
suspend, and disable the override after system resume. Therefore, the
USB3 device will always downgrade to High-speed, then DP/DM wakeup can
always happen. It will correctly switch to Super-speed later when the
host reset it after the system resume back.

Now that the upstream Type-C PHY code is getting broader test coverage we
got reports of USB devices plugged in during boot or those plugged in for
the first time after boot occasionally not working correctly.
This is partially caused by the USB2 parts of the PHY being left in an
unknown state by the previous boot stages. We reset all other parts during
probe but forgot about the USB2 PHY so let's fix that and actually reset
and power off the USB2 PHY as well.
