From 90195c3651800f9a7c14956f90c2b4eb0bc8f1fb Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 23 Feb 2016 10:22:50 +0100 Subject: gpu: ipu-cpmem: modify ipu_cpmem_set_yuv_planar_full for better control Let ipu_cpmem_set_yuv_planar_full take a DRM_FORMAT instead of a V4L2_PIXFMT and allow better control over U/V stride, U offset and V offset settings in the CPMEM.
