I2C-HID #5

Closed jklmnn closed 6 months ago

jklmnn commented 6 years ago

Instead of creating a standalone I2C driver it might be more useful to implement a driver for hid-over-i2c, a generic HID interface for I2C connected devices.

More specific information on how the HID Descriptor can be retrieved: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/hidi2c-device-specific-method---dsm-

Instead of implementing a component that uses acpica by itself the Genode acpica component should be extended to retrieve and publish the HID description table pointer via a report rom and the I2C HID driver should read it.
