From 28258187ce09827121e04b2de19e454032427d96 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 20 Feb 2009 10:30:12 +0100 Subject: v4l2-common/v4l2-spec: support/document write-only and button controls From: Hans Verkuil The controls V4L2_CID_PAN_RESET and V4L2_CID_TILT_RESET changed their type to button controls (these are unused at the moment, so this is a safe change). The controls V4L2_CID_PAN_RELATIVE, V4L2_CID_TILT_RELATIVE, V4L2_CID_FOCUS_RELATIVE and V4L2_CID_ZOOM_RELATIVE are marked as write-only controls.
