From 73f1a5858bf82f3bf2326af2d2adea7305c830de Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 26 Jan 2017 16:32:17 +0100 Subject: drm/fourcc: add vivante tiled layout format modifiers Vivante GC hardware uses simple 4x4 tiled and nested 64x64 supertiled formats as well as so-called split-tiled variants for dual-pipe hardware, where even and odd tiles start at different base addresses.
