From 9f7853ae751849f50486759197d86993551663c2 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 9 Jan 2018 15:36:47 +0200 Subject: [PATCH] drm/omap: set WB channel-in in wb_setup() We need to know the WB channel-in in wb_setup() to be able to configure WB properly for capture mode. At the moment channel-in is set separately. This patch moves channel-in to wb_setup().
