2026-03-05phy: qcom-sgmii-eth: use PHY interface mode for SerDes settingsRussell King (Oracle)
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.

2026-03-05phy: qcom-sgmii-eth: remove .set_speed() implementationRussell King (Oracle)
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 Tested-by: Mohd Ayaan Anwar <mohd.anwar@oss.qualcomm.com> Acked-by: Vinod Koul <vkoul@kernel.org> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Link: https://patch.msgid.link/E1vxS49-0000000BQXa-3Zcg@rmk-PC.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

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 independent SerDes support in the stmmac network driver.

2026-02-27phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4Abel Vesa
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.

2026-02-27phy: lynx-28g: skip CDR lock workaround for lanes disabled in the device treeVladimir Oltean
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.

2026-02-27phy: make PHY_COMMON_PROPS Kconfig symbol conditionally user-selectableVladimir Oltean
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.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
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 *". Signed-off-by: Kees Cook <kees@kernel.org>

divider_determine_rate() 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.
