From 768c3059d87876ce124dafc40078718dc85cec65 Mon Sep 17 00:00:00 2001 From: Rahul Sharma Date: Thu, 4 Oct 2012 20:48:56 +0530 Subject: drm: exynos: hdmi: remove drm common hdmi platform data struct exynos-drm-hdmi need context pointers from hdmi and mixer. These pointers were expected from the plf data. Cleaned this dependency by exporting i/f which are called by hdmi, mixer driver probes for setting their context.
