From 9dc4e48fbea5412127ce2eb30d688c4fc55f5565 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 22 Apr 2008 14:45:32 -0300 Subject: V4L/DVB (7276): soc-camera: deactivate cameras when not used Only attach cameras to the host interface for probing, then detach until open. This allows platforms with several cameras on an interface, physically supporting only one camera, to handle multiple cameras and activate them selectively after initial probing. The first attach during probe is needed to activate the host interface to be able to physically communicate with cameras.
