-From: Takashi Iwai <tiwai@suse.de>
-Subject: [PATCH 2/2] input: Add LED support to Synaptics device
-Patch-mainline: Submitted
-References: bnc#547370,bnc#582529,bnc#589014
-
-The new Synaptics devices have an LED on the top-left corner.
-This patch adds a new LED class device to control it. It's created
-dynamically upon synaptics device probing.
-
-The LED is controlled via the command 0x0a with parameters 0x88 or 0x10.
-This seems only on/off control although other value might be accepted.
-
-The detection of the LED isn't clear yet. It should have been the new
-capability bits that indicate the presence, but on real machines, it
-doesn't fit. So, for the time being, the driver checks the product id
-in the ext capability bits and assumes that LED exists on the known
-devices.
