2025-06-19clk: pwm: Make use of non-sleeping PWMsUwe Kleine-König
For some PWMs applying a configuration doesn't sleep. For these enabling and disabling can be done in the clk callbacks .enable() and .disable() instead of .prepare() and .unprepare(). Do that to possibly reduce the time the PWM is enabled and so save some energy.

2025-06-19clk: pwm: Don't reconfigure running PWM at probe timeUwe Kleine-König
If the PWM is enabled already when .probe() is entered, period and duty_cycle are updated which essentially corresponds to a clock frequency change. This is unusual and surprising. So update the settings only when the clock gets prepared.

pwm_config() is an old function that I'd like to remove. So convert this driver to use pwm_apply_might_sleep(). There is a minor change in behaviour as the explicitly calculated duty_cycle used an uprounding division while pwm_set_relative_duty_cycle() rounds down. I don't expect that difference to matter in practice though.

2025-06-19clk: scmi: Handle case where child clocks are initialized before their parentsSascha Hauer
The SCMI clock driver currently assumes that parent clocks are always initialized before their children. However, this assumption can fail if a child clock is encountered before its parent during probe. This leads to an issue during initialization of the parent_data array: sclk->parent_data[i].hw = hws[sclk->info->parents[i]]; If the parent clock's hardware structure has not been initialized yet, this assignment results in invalid data. To resolve this, allocate all struct scmi_clk instances as a contiguous array at the beginning of the probe and populate the hws[] array upfront. This ensures that any parent referenced later is already initialized, regardless of the order in which clocks are processed. Note that we can no longer free individual scmi_clk instances if scmi_clk_ops_init() fails which shouldn't be a problem if the SCMI platform has proper per-agent clock discovery.

2025-06-19ref_tracker: add a static classname string to each ref_tracker_dirJeff Layton
A later patch in the series will be adding debugfs files for each ref_tracker that get created in ref_tracker_dir_init(). The format will be "class@%px". The current "name" string can vary between ref_tracker_dir objects of the same type, so it's not suitable for this purpose. Add a new "class" string to the ref_tracker dir that describes the the type of object (sans any individual info for that object). Also, in the i915 driver, gate the creation of debugfs files on whether the dentry pointer is still set to NULL. CI has shown that the ref_tracker_dir can be initialized more than once.

Refactor lan78xx_get_link_ksettings and lan78xx_set_link_ksettings to use the phylink API (phylink_ethtool_ksettings_get and phylink_ethtool_ksettings_set) instead of directly interfacing with the PHY. This change simplifies the code and ensures better integration with the phylink framework for link management. Additionally, the explicit calls to usb_autopm_get_interface() and usb_autopm_put_interface() have been removed. These were originally needed to manage USB power management during register accesses. However, lan78xx_mdiobus_read() and lan78xx_mdiobus_write() already handle USB auto power management internally, ensuring that the interface remains active when necessary. Since there are no other direct register accesses in these functions that require explicit power management handling, the extra calls have become redundant and are no longer needed.

2025-06-19net: usb: lan78xx: Rename EVENT_LINK_RESET to EVENT_PHY_INT_ACKOleksij Rempel
The EVENT_LINK_RESET macro currently triggers deferred work after a PHY interrupt. Prior to PHYLINK conversion, this work included reconfiguring the MAC and PHY, effectively performing a 'link reset'. However, after porting the driver to the PHYLINK framework, the logic associated with this event now solely handles the acknowledgment of the PHY interrupt. The MAC and PHY reconfiguration is now managed by PHYLINK's dedicated callbacks. To accurately reflect its current, narrowed functionality, rename EVENT_LINK_RESET to EVENT_PHY_INT_ACK.

2025-06-19net: usb: lan78xx: Convert to PHYLINK for improved PHY and MAC managementOleksij Rempel
Convert the LAN78xx USB Ethernet driver to use the PHYLINK framework for managing PHY and MAC interactions. This improves consistency with other network drivers, simplifies pause frame handling, and enables cleaner suspend/resume support. Key changes: - Replace all PHYLIB-based logic with PHYLINK equivalents: - Replace phy_connect()/phy_disconnect() with phylink_connect_phy() - Replace phy_start()/phy_stop() with phylink_start()/phylink_stop() - Replace pauseparam handling with phylink_ethtool_get/set_pauseparam() - Introduce lan78xx_phylink_setup() to configure PHYLINK - Add phylink MAC operations: - lan78xx_mac_config() - lan78xx_mac_link_up() - lan78xx_mac_link_down() - Remove legacy link state handling: - lan78xx_link_status_change() - lan78xx_link_reset() - Handle fixed-link fallback for LAN7801 using phylink_set_fixed_link() - Replace deprecated flow control handling with phylink-managed logic Power management: - Switch suspend/resume paths to use phylink_suspend()/phylink_resume() - Ensure proper use of rtnl_lock() where required - Note: full runtime testing of power management is currently limited due to hardware setup constraints Note: Conversion of EEE (Energy Efficient Ethernet) handling to the PHYLINK-managed API will be done in a follow-up patch. For now, the legacy EEE enable logic is preserved in mac_link_up().
