From: Philipp Zabel Date: Fri, 14 Dec 2018 16:40:28 +0000 (-0500) Subject: media: gspca: ov534-ov772x: add SGBRG8 bayer mode support X-Git-Tag: v5.4-rc1~1453^2~265 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=52b756aa90713e4d403ef841a9403610de3fd5b5;p=platform%2Fkernel%2Flinux-rpi.git media: gspca: ov534-ov772x: add SGBRG8 bayer mode support Add support to pass through the sensor's native SGBRG8 bayer pattern, allowing to cut the required USB bandwidth in half.
