Subject: [PATCH v2 11/16] gpu: ipu-v3: image-convert: relax input alignment restrictions
Date: Thu, 19 Jul 2018 17:30:37 +0200 [thread overview]
Message-ID: <20180719153042.533-12-p.zabel@pengutronix.de> (raw)
In-Reply-To: <20180719153042.533-1-p.zabel@pengutronix.de>
If we allow the 8-pixel DMA bursts to overshoot the end of the line, the
only input alignment restrictions are dictated by the pixel format and
8-byte aligned line start address.
