usb: misc: Add x86 dependency for Intel USBIO driver

2025-10-13T07:37:47Z

The Intel USBIO driver is x86 only, other architectures have ACPI so add an appropriate depenecy plus compile test. Fixes: 121a0f839dbb3 ("usb: misc: Add Intel USBIO bridge driver") Signed-off-by: Peter Robinson Reviewed-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman

usb: misc: Add Intel USBIO bridge driver

2025-09-12T12:05:09Z

Add a driver for the Intel USBIO USB IO-expander used by the MIPI cameras on various new (Meteor Lake and later) Intel laptops. This is an USB bridge driver which adds auxbus child devices for the GPIO, I2C and SPI functions of the USBIO chip and which exports IO-functions for the drivers for the auxbus child devices to communicate with the USBIO device's firmware.

usb: usb251xb: support usage case without I2C control

2025-09-06T13:23:29Z

Currently, the usb251xb assumes i2c control. But from HW point of view, the hub supports usage case without any i2c, we only want the gpio controls. Refactor the code so that register writes for configuration are only performed if the device has a i2c_client provided and also register as a platform driver. This allows the driver to be used to manage GPIO based control of the device.

Use the modern PM macros for the suspend and resume functions to be automatically dropped by the compiler when CONFIG_PM or CONFIG_PM_SLEEP are disabled, without having to use __maybe_unused.

usb: misc: qcom_eud: Access EUD_MODE_MANAGER2 through secure calls

2025-08-13T15:13:45Z

EUD_MODE_MANAGER2 register is mapped to a memory region that is marked as read-only for operating system running at EL1, enforcing access restrictions that prohibit direct memory-mapped writes via writel(). Attempts to write to this region from HLOS can result in silent failures or memory access violations, particularly when toggling EUD (Embedded USB Debugger) state. To ensure secure register access, modify the driver to use qcom_scm_io_writel(), which routes the write operation to Qualcomm Secure Channel Monitor (SCM). SCM has the necessary permissions to access protected memory regions, enabling reliable control over EUD state. SC7280, the only user of EUD is also affected, indicating that this could never have worked on a properly fused device.

usb: misc: eud: Remove error print for devm_add_action_or_reset()

2025-08-13T14:55:36Z

When `devm_add_action_or_reset()` fails, it is due to a failed memory allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do anything when error is `-ENOMEM`. Therefore, remove the useless call to `dev_err_probe()` when `devm_add_action_or_reset()` fails, and just return the value instead.

usb: misc: apple-mfi-fastcharge: Make power supply names unique

2025-06-19T10:25:59Z

When multiple Apple devices are connected concurrently, the apple-mfi-fastcharge driver fails to probe the subsequent devices with the following error: sysfs: cannot create duplicate filename '/class/power_supply/apple_mfi_fastcharge' apple-mfi-fastcharge 5-2.4.3.3: probe of 5-2.4.3.3 failed with error -17 This happens because the driver uses a fixed power supply name ("apple_mfi_fastcharge") for all devices, causing a sysfs name conflict when a second device is connected. Fix this by generating unique names using the USB bus and device number (e.g., "apple_mfi_fastcharge_5-12"). This ensures each connected device gets a unique power supply entry in sysfs. The change requires storing a copy of the power_supply_desc structure in the per-device mfi_device struct, since the name pointer needs to remain valid for the lifetime of the power supply registration.
