From 24e64f86da40e68c5f58af08796110f147b12193 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 24 Jul 2019 17:06:17 +0200 Subject: [PATCH] drm/tegra: sor: Use correct SOR index on Tegra210 The device tree bindings for the Tegra210 SOR don't require the controller instance to be defined, since the instance can be derived from the compatible string. The index is never used on Tegra210, so we got away with it not getting set. However, subsequent patches will change that, so make sure the proper index is used.
