From 7db42b1718dac7aa67ec68acad177164516af71d Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 23 Apr 2026 17:21:16 +0300 Subject: [PATCH] drm/fourcc: Add DRM_FORMAT_T430 Add T430, a 3 plane 10 bits per component non-subsampled YCbCr format. A new initial letter was chosen for this one, as the format doesn't match the existing P, Q or S formats. T is the next one in the alphabet. It was definitely not chosen because of the initial letter in the author's name.
