Subject: [PATCH v4 02/25] drm/dp: Add DP DSC DPCD receiver capability size define and missing SHIFT
Date: Tue, 11 Sep 2018 17:55:44 -0700	[thread overview]
Message-ID: <20180912005607.29522-3-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20180912005607.29522-1-manasi.d.navare@intel.com>

This patch defines the DP DSC receiver capability size that gives
total number of DP DSC DPCD registers.
This also adds a missing #defines for DP DSC support missed in the
commit id (ab6a46ea6842ce "Add DPCD definitions for DP 1.4 DSC feature")

v3:
* MIN_SLICE_WIDTH = 2560 (Anusha)
* Define DP_DSC_SLICE_WIDTH_MULTIPLIER = 320
v2:
* Add SHIFT define and DECOMPRESSION_EN define missed in prev patch
