Subject: [PATCH v4 4/5] media: Add HEXTILE compressed format
Date: Mon, 23 May 2022 13:25:47 +0800 [thread overview]

In-Reply-To: <20220523052548.28109-1-milkfafa@gmail.com>
Add HEXTILE compressed format. This format is defined in Remote Framebuffer
Protocol (RFC 6143) and is used by Encoding Compression Engine present on
Nuvoton NPCM SoCs.
