From 21cd1fab058671313f7c178b640999fcd0d8de21 Mon Sep 17 00:00:00 2001 From: Jon Brenner Date: Wed, 16 May 2012 10:46:42 -0500 Subject: IIO channel type and modifiers for CCT and RGBC data Add iio channel type and modifiers for Correlated Color Temperature (CCT) and RGBC (red/green/blue/clear) data. Add CCT and RGBC descriptions to documentation. Changes: Revised/condensed RGBC descriptions. Merge and trivial fix done by Jonathan Cameron.
