From 28269b219a1a489e99a51ba70c3b46417eb38993 Mon Sep 17 00:00:00 2001 From: Mark Yao Date: Thu, 15 Dec 2016 10:27:20 +0800 Subject: [PATCH] drm/panel: support get bus_format from device-tree copy include/uapi/linux/media-bus-format.h to include/dt-bindings/display/media-bus-format.h So we can use media bus format on device-tree.
