From e34cc1b6b7115de2320c2acdb62c82ebeb502c01 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 1 Jul 2015 18:13:46 +0900 Subject: [PATCH] ARM: tegra: venice2: Add GK20A GPU DT node Add the device-tree node for the GK20A GPU and leave it disabled. It is the responsibility of the bootloader to enable it if the VPR registers have been programmed such that the GPU can operate.
