2025-09-16hinic3: Fix missing napi->dev in netif_queue_set_napiFan Gong
As netif_queue_set_napi checks napi->dev, if it doesn't have it and it will warn_on and return. So we should use netif_napi_add before netif_queue_set_napi because netif_napi_add has "napi->dev = dev".

2025-09-16HID: i2c-hid: Resolve touchpad issues on Dell systems during S4Mario Limonciello (AMD)
Dell systems utilize an EC-based touchpad emulation when the ACPI touchpad _DSM is not invoked. This emulation acts as a secondary master on the I2C bus, designed for scenarios where the I2C touchpad driver is absent, such as in BIOS menus. Typically, loading the i2c-hid module triggers the _DSM at initialization, disabling the EC-based emulation. However, if the i2c-hid module is missing from the boot kernel used for hibernation snapshot restoration, the _DSM remains uncalled, resulting in dual masters on the I2C bus and subsequent arbitration errors. This issue arises when i2c-hid resides in the rootfs instead of the kernel or initramfs. To address this, switch from using the SYSTEM_SLEEP_PM_OPS() macro to dedicated callbacks, introducing a specific callback for restoring the S4 image. This callback ensures the _DSM is invoked.

2025-09-15scsi: ufs: ufs-qcom: Disable lane clocks during phy hibern8Palash Kambar
Currently, the UFS lane clocks remain enabled even after the link enters the Hibern8 state and are only disabled during runtime/system suspend.This patch modifies the behavior to disable the lane clocks during ufs_qcom_setup_clocks(), which is invoked shortly after the link enters Hibern8 via gate work. While hibern8_notify() offers immediate control, toggling clocks on every transition isn't ideal due to varied contexts like clock scaling. Since setup_clocks() manages PHY/controller resources and is invoked soon after Hibern8 entry, it serves as a central and stable point for clock gating.

2025-09-15net: pcs: rzn1-miic: Add per-SoC control for MIIC register unlock/lockLad Prabhakar
Make MIIC accessory register unlock/lock behaviour selectable via SoC/OF data. Add init_unlock_lock_regs and miic_write to struct miic_of_data so the driver can either perform the traditional global unlock sequence (as used on RZ/N1) or use a different policy for other SoCs (for example RZ/T2H, which does not require leaving registers unlocked). miic_reg_writel() now calls the per-SoC miic_write callback to perform register writes. Provide miic_reg_writel_unlocked() as the default writer and set it for the RZ/N1 OF data so existing platforms keep the same behaviour. Add a miic_unlock_regs() helper that implements the accessory register unlock sequence so the unlock/lock sequence can be reused where needed (for example when a SoC requires explicit unlock/lock around individual accesses). This change is preparatory work for supporting RZ/T2H.

2025-09-15net: pcs: rzn1-miic: Add support to handle resetsLad Prabhakar
Add reset-line handling to the RZN1 MIIC driver and move reset configuration into the SoC/OF data. Introduce MIIC_MAX_NUM_RSTS (= 2), add storage for reset_control_bulk_data in struct miic and add reset_ids and reset_count fields to miic_of_data. When reset_ids are present in the OF data, the driver obtains the reset lines with devm_reset_control_bulk_get_exclusive(), deasserts them during probe and registers a devres action to assert them on remove or on error. This change is preparatory work to support the RZ/T2H SoC, which exposes two reset lines for the ETHSS IP. The driver remains backward compatible for platforms that do not provide reset lines.

Move the hardcoded switch mode mask definition into the SoC-specific miic_of_data structure. This allows each SoC to define its own mask value rather than relying on a single fixed constant.

Replace uses of the hard-coded MIIC_MAX_NR_PORTS with the SoC-provided miic_port_max when iterating over ports. On RZ/N1 the MIIC ports are numbered 1..5, whereas RZ/T2H numbers its MIIC ports 0..3. By making the port base and range part of the OF data the driver no longer assumes a fixed numbering scheme and can support SoCs that enumerate ports from either zero or one and that expose different numbers of ports. This change is preparatory work for adding RZ/T2H support.
