Subject: drm/i915/tgl: allow the reg_read ioctl to read the RCS TIMESTAMP
register
Git-commit: 2b92a82fe03bd426a90b82d69fe1c340ac6b9d74
Patch-mainline: v5.4-rc1
References: bsc#1152489
This enables the Mesa driver to advertise support for ARB_timer_query,
and thus an OpenGL version higher than 3.2.
Based on the ICL patch by Paulo Zanoni and CNL patch by Nanley Chery.
