Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+
+infrared remote control support in video4linux drivers
+======================================================
+
+
+basics
+------
+
+Current versions use the linux input layer to support infrared
+remote controls.  I suggest to download my input layer tools
+from http://bytesex.org/snapshot/input-<date>.tar.gz
+
+Modules you have to load:
+
+  saa7134	statically built in, i.e. just the driver :)
+  bttv		ir-kbd-gpio or ir-kbd-i2c depending on your
+		card.
+
+ir-kbd-gpio and ir-kbd-i2c don't support all cards lirc supports
+(yet), mainly for the reason that the code of lirc_i2c and lirc_gpio
+was very confusing and I decided to basically start over from scratch.
+Feel free to contact me in case of trouble.  Note that the ir-kbd-*
+modules work on 2.6.x kernels only through ...
+
+
+how it works
+------------
+
+The modules register the remote as keyboard within the linux input
+layer, i.e. you'll see the keys of the remote as normal key strokes
+(if CONFIG_INPUT_KEYBOARD is enabled).
+
+Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
+applications to access the remote via /dev/input/event<n> devices.
+You might have to create the special files using "/sbin/MAKEDEV
+input".  The input layer tools mentioned above use the event device.
+
+The input layer tools are nice for trouble shooting, i.e. to check
+whenever the input device is really present, which of the devices it
+is, check whenever pressing keys on the remote actually generates
+events and the like.  You can also use the kbd utility to change the
+keymaps (2.6.x kernels only through).
+
+
+using with lircd
+================
+
+The cvs version of the lircd daemon supports reading events from the
+linux input layer (via event device).  The input layer tools tarball
+comes with a lircd config file.
+
+
+using without lircd
+===================
+
+XFree86 likely can be configured to recognise the remote keys.  Once I
+simply tried to configure one of the multimedia keyboards as input
+device, which had the effect that XFree86 recognised some of the keys
+of my remote control and passed volume up/down key presses as
+XF86AudioRaiseVolume and XF86AudioLowerVolume key events to the X11
+clients.
+
+It likely is possible to make that fly with a nice xkb config file,
+I know next to nothing about that through.
+
+
+Have fun,
+
