[v2,0/4] DeviceTree Support for USB-HID Devices and CP2112

Message

Daniel Kaehn Feb. 4, 2023, 4:43 a.m. UTC

This patchset allows USB-HID devices to have DeviceTree bindings through sharing
the USB of_node with the HID driver, and adds such a binding and driver
implementation for the CP2112 USB to SMBus Bridge (which necessitated the
USB-HID change). This change allows a CP2112 permanently attached in hardware to
be described in DT and interoperate with other drivers, and exposed the threaded
interrupt bug fixed in patch 0003.

Changes in v2:
 - Added more detail to silabs,cp2112.yaml dt-binding
 - Moved silabs,cp2112.yaml to /Documentation/devicetree/bindings/input
 - Added support for setting smbus clock-frequency from DT in hid-cp2112.c
 - Added freeing of of_nodes on error paths of _probe in hid-cp2112.c
