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.

2025-03-25Bluetooth: btnxpuart: Add support for HCI coredump featureNeeraj Sanjay Kale
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.

2025-03-25Bluetooth: btnxpuart: Move vendor specific initialization to .post_initNeeraj Sanjay Kale
This moves change baudrate and power save vendor commands from nxp_setup() to nxp_post_init(). 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.

__bch2_read, before calling __bch2_read_extent(), sets bvec_iter.bi_size to "the size we can read from the current extent" with a swap, and restores it to "the size for the total read" after the read_extent call with another swap. But we neglected to do the restore before the "if (ret) goto err;" - which is a problem if we're retrying those errors. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
