From b0cd79ed987c7b362a2e1a339ce9959192dc2f52 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Mon, 16 Jan 2012 18:59:02 -0300 Subject: [PATCH] [media] omap3isp: Move setting constaints above media_entity_pipeline_start The clock rate for l3_ick will soon be read during pipeline validation which is now part of media_entity_pipeline_start(). For that reason we set constraints earlier on.
