This simple patch adds support to i2c-parport for the OneForAll remote JP1 parallel port interfaces which can be found detailed at:
http://www.hifi-remote.com/jp1/hardware.shtml These allow access to the internal configuration EEPROM on various remote controls and there are a variety of Windows tools that make use of this hardware. I have tested this patch with the "simple" parallel port device and a OneForAll URC-7562 and confirmed that the data read using the eeprom i2c driver matches that returned by the Windows "IR" JP1 tool.
