Subject: [PATCH] drm/i915/cnl: Allow the reg_read ioctl to read the RCS TIMESTAMP register
Git-commit: f1294585d8e177b25acd028d90f23f335d6695fb
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900
This enables the Mesa driver to advertise support for ARB_timer_query, and
thus an OpenGL version higher than 3.2.
