phy: lynx-10g: use RCW override procedure for dynamic protocol change

2026-08-07T04:54:23+00:00

Up until this patch, the only protocol change supported was between 1000Base-X/SGMII and 2500Base-X. The others require an RCW override procedure which was lacking. Since now the guts driver provides the means of applying this procedure, make use of it and remove any comment which mentioned the limitation.

phy: freescale: fsl-samsung-hdmi: Balance runtime PM operations

2026-08-06T16:18:29+00:00

fsl_samsung_hdmi_phy_probe() enables runtime PM, but the remove callback does not disable it. Unbinding and rebinding the device therefore results in the following warning on reprobe: Unbalanced pm_runtime_enable! Disable runtime PM after removing the clock provider. Also undo the runtime PM operations when phy_clk_register() fails. Otherwise, a failed probe leaves runtime PM enabled and the usage counter incremented.

phy: fsl-imx8mq-usb: keep PHY power domain runtime always-on for i.MX8MP

2026-08-06T15:45:09+00:00

On i.MX8MP, the USB PHY has a dedicated power domain that was previously never powered off at runtime. With the introduction of runtime PM support, the power domain will be powered off if the device is runtime suspended, which breaks USB wakeup functionality. To preserve wakeup functionality, mark the PHY power domain as runtime always-on for i.MX8MP platform. To limit the behavior to i.MX8MP, add a need_genpd_rpm_on to imx8mq_usb_phy_drvdata and set it as true for i.MX8MP.

phy: fsl-imx8mq-usb: introduce per-variant driver data structure

2026-08-06T15:45:08+00:00

Replace direct use of phy_ops pointer in of_device_id .data with a dedicated imx8mq_usb_phy_drvdata structure. This allows per-variant driver data to be extended in the future without changing the match table.

phy: fsl-imx8mq-usb: add control register regmap

2026-08-06T15:45:08+00:00

The CR port is a simple 16-bit data/address parallel port that is accessed through 32-bit MMIO registers for on-chip access to the control registers inside the USB 3.0 femtoPHY. Add control register regmap and export these registers by debugfs to help PHY's diagnostic.

phy: fsl-imx8mq-usb: add runtime PM support

2026-08-06T15:45:08+00:00

Add runtime PM support to ensure the PHY clocks are properly gated when the PHY is not in use, reducing power consumption. Clock management is moved from power_on()/power_off() callbacks into the runtime_resume()/runtime_suspend() callbacks respectively. The PHY subsystem core already holds a runtime PM reference around init() and power_on/off() calls, so no explicit clock handling is needed there. Use devm_clk_get_enabled() and devm_clk_get_optional_enabled() in probe() to keep clocks enabled initially. This ensures the PHY remains functional when CONFIG_PM is disabled, where runtime suspend/resume callbacks are never invoked. In tca_blk_typec_switch_set(), replace the manual clk_prepare_enable() / clk_disable_unprepare() pair with PM_RUNTIME_ACQUIRE_IF_ENABLED() to guard register access against a concurrently suspended PHY. Move devm_regulator_get() before pm_runtime_enable() to avoid having to clean up runtime PM state on regulator acquisition failure. In remove(), call pm_runtime_get_sync() before pm_runtime_disable() to ensure the PHY is resumed and clocks are enabled before the devres teardown disables them.

phy: fsl-imx8mq-usb: fix typec switch leak on probe error path

2026-08-06T15:45:08+00:00

If probe fails after imx95_usb_phy_get_tca() succeeds, the typec switch leaks because the only cleanup path was in .remove(), which never runs on probe failure. Use devm_add_action_or_reset() so the switch is cleaned up on both probe failure and driver removal. The imx95_usb_phy_put_tca() is no longer needed, it will be removed in .remove() too.

phy: lynx-10g: fix lynx_10g_pccr_val_enabled()

2026-07-22T08:08:07+00:00

The intention of the code is to extract the PCCR8_SGMIIa_CFG field out of the "pccr" value, not to create a new value with the PCCR8_SGMIIa_CFG field set to the "pccr" value. Since FIELD_GET() is implemented as ((reg) & (mask)) >> __bf_shf(mask) and FIELD_PREP() as (val) << __bf_shf(mask)) & (mask) and since "mask" is GENMASK(2, 0), in practice there is no functional difference between FIELD_GET() and FIELD_PREP(). But FIELD_GET() is logically the correct helper. Signed-off-by: Vladimir Oltean Link: https://patch.msgid.link/20260612125731.133330-1-vladimir.oltean@nxp.com Signed-off-by: Vinod Koul
