From 55249cf750e4d9be19c7f8afd502c9ca42de8858 Mon Sep 17 00:00:00 2001 From: Jonathan McDowell Date: Tue, 13 Feb 2007 22:09:02 +0100 Subject: [PATCH] i2c-parport: Add support for One For All remote JP1 interface This simple patch adds support to i2c-parport for the One For All 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 One For All URC-7562 and confirmed that the data read using the eeprom i2c driver matches that returned by the Windows "IR" JP1 tool.
