Message-Id: <200910201000.57536.jarod@redhat.com>
Date: Tue, 20 Oct 2009 10:00:57 -0400
From: Jarod Wilson <jarod@...hat.com>

Subject: [PATCH 3/3 v2] lirc driver for SoundGraph iMON IR receivers and displays
lirc driver for SoundGraph iMON IR receivers and displays
Successfully tested with multiple devices with and without displays.
Changes from prior submission:
- dual-endpoint devices now appear as a single lirc device
- proper support for devices with touchscreens
- full input device support for mouse mode
- full input device support for onboard decoding devices,
with modparam fallback option for classic lirc mode
- auto-detection of lcd/vfd/vga display in most cases
- support for several new devices
- uses dev_foo printk macros
- able to decode both imon and mce protocol
