Subject: [PATCH v3 03/19] drm: add msm compressed format modifiers
Date: Fri, 20 Jul 2018 16:42:54 -0400	[thread overview]
Message-ID: <20180720204315.19054-4-seanpaul@chromium.org> (raw)
In-Reply-To: <20180720204315.19054-1-seanpaul@chromium.org>

From: Jeykumar Sankaran <jsanka@codeaurora.org>

Qualcomm Snapdragon chipsets uses compressed format
to optimize BW across multiple IP's. This change adds
needed modifier support in drm for a simple 4x4 tile
based compressed variants of base formats.

Changes in v3:
- Removed duplicate entry for DRM_FORMAT_MOD_QCOM_COMPRESSED (Rob Clark)
