From ec1afbf4e1025f74e636ada2e7da3963c8da4c06 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Fri, 27 Jun 2014 20:36:54 +0900 Subject: [PATCH] drm/gk20a: add BAR instance GK20A's BAR is functionally identical to NVC0's, but do not support being ioremapped write-combined. Create a BAR instance for GK20A that reflect that state.
