Subject: [PATCH v3 3/5] media: vsp1: Document partition algorithm in code header
Date: Thu, 11 Apr 2019 17:12:54 +0100 [thread overview]
Message-ID: <20190411161256.19607-4-kieran.bingham+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190411161256.19607-1-kieran.bingham+renesas@ideasonboard.com>
The image partition algorithm operates on the image dimensions as input
into the WPF entity. Document this in the code block header.
