From f25d0a68beb868147571e395de52ced0c55f6cd4 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 10 Dec 2018 17:34:54 +0100 Subject: [PATCH] drm/tegra: Refactor CEC support Most of the CEC support code already lives in the "output" library code. Move registration and unregistration to the library code as well to make use of the same code with HDMI on Tegra210 and later via the SOR.
