From d3918ffc89527a22f0ba31095387201cee5aff10 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 23 Dec 2008 09:54:45 +0100 Subject: soc-camera: Add signal inversion flags to be used by camera drivers From: Guennadi Liakhovetski As reported by Antonio Ospite two platforms with a mt9m111 camera require opposite pixel clock polarity, which means one of them inverts it. This patch adds support for inversion flags and switches all available camera drivers to using them.
