From cff765fb1383dff6787fa735fcc88aa122d3c00d Mon Sep 17 00:00:00 2001 From: Animesh Manna Date: Tue, 4 Aug 2015 22:02:43 +0530 Subject: [PATCH] drm/i915/bxt: Stepping info added for bxt. Added stepping info in intel_csr.c which is required to extract specific firmware from packaged dmc firmware. Stepping info is aligned with current bspec info.
