2025-03-25stmmac: Remove pcim_* functions for driver detachPhilipp Stanner
Functions prefixed with "pcim_" are managed devres functions which perform automatic cleanup once the driver unloads. It is, thus, not necessary to call any cleanup functions in remove() callbacks. Remove the pcim_ cleanup function calls in the remove() callbacks.

2025-03-25stmmac: loongson: Remove surplus loopPhilipp Stanner
loongson_dwmac_probe() contains a loop which doesn't have an effect, because it tries to call pcim_iomap_regions() with the same parameters several times. The break statement at the loop's end furthermore ensures that the loop only runs once anyways. Remove the surplus loop.

2025-03-25Merge tag 'irq-drivers-2025-03-23' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq driver updates from Thomas Gleixner: - Support for hard indices on RISC-V. The hart index identifies a hart (core) within a specific interrupt domain in RISC-V's Priviledged Architecture. - Rework of the RISC-V MSI driver This moves the driver over to the generic MSI library and solves the affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI controllers are prone to lose interrupts when the MSI message is updated to change the affinity because the message write consists of three 32-bit subsequent writes, which update address and data. As these writes are non-atomic versus the device raising an interrupt, the device can observe a half written update and issue an interrupt on the wrong vector. This is mitiated by a carefully orchestrated step by step update and the observation of an eventually pending interrupt on the CPU which issues the update. The algorithm follows the well established method of the X86 MSI driver. - A new driver for the RISC-V Sophgo SG2042 MSI controller - Overhaul of the Renesas RZQ2L driver Simplification of the probe function by using devm_*() mechanisms, which avoid the endless list of error prone gotos in the failure paths. - Expand the Renesas RZV2H driver to support RZ/G3E SoCs - A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to ensure that the addressing is limited to the lower 32-bit of the physical address space. - Add support for the Allwinner AS23 NMI controller - Expand the IMX irqsteer driver to handle up to 960 input interrupts - The usual small updates, cleanups and device tree changes * tag 'irq-drivers-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) irqchip/imx-irqsteer: Support up to 960 input interrupts irqchip/sunxi-nmi: Support Allwinner A523 NMI controller dt-bindings: irq: sun7i-nmi: Document the Allwinner A523 NMI controller irqchip/davinci-cp-intc: Remove public header irqchip/renesas-rzv2h: Add RZ/G3E support irqchip/renesas-rzv2h: Update macros ICU_TSSR_TSSEL_{MASK,PREP} irqchip/renesas-rzv2h: Update TSSR_TIEN macro irqchip/renesas-rzv2h: Add field_width to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add max_tssel to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add struct rzv2h_hw_info with t_offs variable irqchip/renesas-rzv2h: Use devm_pm_runtime_enable() irqchip/renesas-rzv2h: Use devm_reset_control_get_exclusive_deasserted() irqchip/renesas-rzv2h: Simplify rzv2h_icu_init() irqchip/renesas-rzv2h: Drop irqchip from struct rzv2h_icu_priv irqchip/renesas-rzv2h: Fix wrong variable usage in rzv2h_tint_set_type() dt-bindings: interrupt-controller: renesas,rzv2h-icu: Document RZ/G3E SoC riscv: sophgo: dts: Add msi controller for SG2042 irqchip: Add the Sophgo SG2042 MSI interrupt controller dt-bindings: interrupt-controller: Add Sophgo SG2042 MSI arm64: dts: rockchip: rk356x: Move PCIe MSI to use GIC ITS instead of MBI ...

2025-03-25Bluetooth: btnxpuart: Add support to set BD addressNeeraj Sanjay Kale
This adds support for setting BD address during hci registration. NXP FW does not allow vendor commands unless it receives a reset command after FW download and initialization done. As a workaround, the .set_bdaddr callback function will first send the HCI reset command, followed by the actual vendor command to set BD address. The driver checks for the local-bd-address property in device tree, and if preset, it sets the HCI_QUIRK_USE_BDADDR_PROPERTY quirk. With this quirk set, the driver's set_bdaddr callback function is called after FW download is complete and before HCI initialization, which sends the hci reset and 3f 22 commands. During initialization, kernel reads the newly set BD address from the controller.

This adds support for Bluetooth Coredump feature to BTNXPUART driver to collect FW dumps on demand, or in case FW goes in a bad state. To trigger manual FW dump, following command can be used: echo 1 > /sys/class/bluetooth/hci0/device/coredump Once FW dump is complete, it can be written to a file: cat /sys/class/bluetooth/hci0/devcoredump/data > fw_dump While FW dump is in progress, any HCI command will return -EBUSY. After FW dump is complete, driver will give HCI_NXP_IND_RESET command which soft-resets the chip, allowing FW re-download.

This also moves the baudrate restore logic from nxp_serdev_remove() to nxp_shutdown() which ensure baudrate is restored even when HCI dev is down, preventing baudrate mismatch between host and controller when device is probed again next time. In case of removal when the hdev is up and running, we have to call the shutdown procedure explicitly before unregistering the hdev.

2025-03-25Bluetooth: hci_uart: Fix another race during initializationArseniy Krasnov
Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'. Possible race is when someone calls 'hci_tty_uart_close()' after this bit is set, but 'hci_uart_register_dev()' wasn't done. This leads to access to uninitialized fields. To fix it let's set this bit after device was registered (as before patch c411c62cc133) and to fix previous problem let's add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to perform power up without original bit set (pls see commit c411c62cc133).

2025-03-25Bluetooth: hci_uart: fix race during initializationArseniy Krasnov
'hci_register_dev()' calls power up function, which is executed by kworker - 'hci_power_on()'. This function does access to bluetooth chip using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'. Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after 'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will be executed before setting this bit. In that case HCI init logic fails. Patch moves setting of 'HCI_UART_PROTO_READY' before calling function 'hci_uart_register_dev()'.

2025-03-25net: mdio: mdio-i2c: Add support for single-byte SMBus operationsMaxime Chevallier
PHYs that are within copper SFP modules have their MDIO bus accessible through address 0x56 (usually) on the i2c bus. The MDIO-I2C bridge is desgned for 16 bits accesses, but we can also perform 8bits accesses by reading/writing the high and low bytes sequentially. This commit adds support for this type of accesses, thus supporting smbus controllers such as the one in the VSC8552. This was only tested on Copper SFP modules that embed a Marvell 88e1111 PHY.

2025-03-25net: phy: sfp: Add support for SMBus module accessMaxime Chevallier
The SFP module's eeprom and internals are accessible through an i2c bus. It is possible that the SFP might be connected to an SMBus-only controller, such as the one found in some PHY devices in the VSC85xx family. Introduce a set of sfp read/write ops that are going to be used if the i2c bus is only capable of doing smbus byte accesses. As Single-byte SMBus transaction go against SFF-8472 and breaks the atomicity for diagnostics data access, hwmon is disabled in the case of SMBus access. Moreover, as this may cause other instabilities, print a warning at probe time to indicate that the setup may be unreliable because of the hardware design. As hwmon may be disabled for both broken EEPROM and smbus, the warnings are udpated accordingly.
