From c134f019abcfaa1cb6e07f6154e92a4f8ce8ddd8 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 3 Jun 2014 14:48:12 +0200 Subject: drm/tegra: Implement more tiling modes Tegra124 supports a block-linear mode in addition to the regular pitch linear and tiled modes. Add support for these by moving the internal representation into a structure rather than a simple flag.
