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

According to internal documentation, on SM8650, when the PHY is configured
in Gear 4, the QPHY_V6_PCS_UFS_PLL_CNTL register needs to have the same
value as for Gear 5.
At the moment, there is no board that comes with a UFS 3.x device, so
this issue doesn't show up, but with the new Eliza SoC, which uses the
same init sequence as SM8650, on the MTP board, the link startup fails
with the current Gear 4 PCS table.
So fix that by moving the entry into the PCS generic table instead,
while keeping the value from Gear 5 configuration.

The driver currently sets bit 0 of USB_PHY_CFG1 (PLL_EN) during PHY
initialization. According to the M31 EUSB2 PHY hardware documentation,
this bit is intended only for test/debug scenarios and does not control
mission mode operation. Keeping PLL_EN asserted causes the PHY to draw
additional current during USB bus suspend. Clearing this bit results in
lower suspend power consumption without affecting normal operation.
Update the driver to leave PLL_EN cleared as recommended by the hardware
documentation.

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.

xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL

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.

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.

Kconfig option CONFIG_PHY_COMMON_PROPS, which builds
drivers/phy/phy-common-props.c, was intended to be selectable
independently of CONFIG_GENERIC_PHY. Yet it lives in drivers/phy/, which
is entered by the Makefile only if CONFIG_GENERIC_PHY is set.
Allow the Makefile to enter one level deeper, but stop at drivers/phy/
if CONFIG_GENERIC_PHY is unselected (i.e. do not enter vendor folders).
The other stuff from drivers/phy/Makefile except for CONFIG_PHY_COMMON_PROPS,
like CONFIG_PHY_NXP_PTN3222, all depends on CONFIG_GENERIC_PHY.

Enable OTG VBUS control on R-Car Gen3 USB2 PHY by registering a regulator
driver that manages the VBOUT line. This change allows the controller to
handle VBUS output for OTG ports using the regulator framework when the
platform requires hardware-based VBUS control.
Without this, some platforms cannot properly manage VBUS power on OTG-
capable ports, leading to potential USB functionality issues.

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
switches between TMDS and FRL rates, without requiring additional checks
of the active PHY mode followed by recalculations of the link rate when
operating in FRL mode.

The ->hw_rate member of struct rk_hdptx_phy was mainly used to keep
track of the clock rate programmed in hardware and support implementing
the ->recalc_rate() callback in hdptx_phy_clk_ops.
Computing the clock rate from the actual PHY PLL configuration seems to
work reliably, hence remove the now redundant struct member.

Drop redundant reg_sequence entries from rk_hdptx_common_cmn_init_seq[],
i.e. those that are either duplicated or overridden in
rk_hdptx_tmds_cmn_init_seq[].
Additionally, a few items do not really belong to the former, hence move
them to the latter. That's mostly a preparatory step for adding FRL
support.
