Subject: [PATCH 1/2] drm: mali-dp: Add plane offset to the plane's physical start address register
Date: Thu, 26 Jan 2017 15:31:10 +0000 [thread overview]
Message-ID: <20170126153111.18813-1-Liviu.Dudau@arm.com> (raw)
Add the fb->offset[] value to the plane's physical start address
registe. Without that, packed formats are rendered incorrectly.
