From 05f8bc82fc428dbaf41764e95167dd759769f33d Mon Sep 17 00:00:00 2001 From: Randy Li Date: Thu, 10 Jan 2019 03:57:09 +0800 Subject: drm/fourcc: Add new P010, P016 video format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit P010 is a planar 4:2:0 YUV with interleaved UV plane, 10 bits per channel video format. P012 is a planar 4:2:0 YUV 12 bits per channel P016 is a planar 4:2:0 YUV with interleaved UV plane, 16 bits per channel video format. V3: Added P012 and fixed cpp for P010. V4: format definition refined per review. V5: Format comment block for each new pixel format. V6: reversed Cb/Cr order in comments. v7: reversed Cb/Cr order in comments of header files, remove the wrong part of commit message. V8: reversed V7 changes except commit message and rebased. v9: used the new properties to describe those format and rebased.
