From mboxrd@z Thu Jan 1 00:00:00 1970 From: acourbot@nvidia.com (Alexandre Courbot) Date: Wed, 1 Jul 2015 18:13:47 +0900 Subject: [PATCH 3/4] ARM: tegra: jetson-tk1: Add GK20A GPU DT node In-Reply-To: <1435742028-8237-1-git-send-email-acourbot@nvidia.com> References: <1435742028-8237-1-git-send-email-acourbot@nvidia.com> Message-ID: <1435742028-8237-4-git-send-email-acourbot@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add the device-tree node for the GK20A GPU and leave it disabled. It is the responsability of the bootloader to enable it if the VPR registers have been programmed such as the GPU can operate.
