Subject: [PATCH v7 0/3] Firmware Support for USB-HID Devices and CP2112
Date: Thu, 23 Feb 2023 15:31:44 -0600 [thread overview]
Message-ID: <20230223213147.268-1-kaehndan@gmail.com> (raw)
This patchset allows USB-HID devices to have DeviceTree bindings through sharing
the USB fwnode 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.
Changes in v7:
- Use dev_fwnode when calling fwnod_handle_put in i2c_adapter in hid-cp2112.c
- Capitalize I2C and GPIO in commit message for patch 0003
Changes in v6:
- Fix fwnode_handle reference leaks in hid-cp21112.c
- Simplify hog node pattern in silabs,cp2112.yaml
Changes in v5:
- Use fwnode API instead of of_node api in hid-core.c and hid-cp2112.c
- Include sda-gpios and scl-gpios in silabs,cp2112.yaml
- Additional fixups to silabs,cp2112.yaml to address comments
- Submit threaded interrupt bugfix separately from this patchset, as requested
Changes in v4:
- Moved silabs,cp2112.yaml to /Documentation/devicetree/bindings/i2c
Changes in v3:
- Additional fixups to silabs,cp2112.yaml to address comments
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
