From 88c0292f023da4e4753a271430a36a66e6fb974f Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Mon, 27 Jun 2022 17:19:52 +0300 Subject: [PATCH] drm/tegra: nvdec: Fix TRANSCFG register offset NVDEC's TRANSCFG register is at a different offset than VIC. This becomes a problem now when context isolation is enabled and the reset value of the register is no longer sufficient.
