From: Tomi Valkeinen Date: Thu, 23 Apr 2026 14:21:13 +0000 (+0300) Subject: drm/fourcc: Add DRM_FORMAT_P230 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b718f041842071b8c09faf658e3adca7b506e1bb;p=thirdparty%2Fkernel%2Flinux.git drm/fourcc: Add DRM_FORMAT_P230 Add a new pixel format, DRM_FORMAT_P230 ("P230") P230 is 2 plane 10 bit per component YCbCr 2x1 subsampled format. P230 is similar to the already existing P030 format, which is 2x2 subsampled.
