From 954b81b93de3cc6baa9e2ebdd4e8dc7b63dab71a Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Thu, 16 Nov 2017 14:22:30 +0000 Subject: [PATCH 181/454] drm/vc4: Use .pixel_order instead of custom .flip_cbcr The hardware has enums for altering the Cr and Cb order, so use this instead of having a flag which swaps the order the pointers are presented to the hardware (that only worked for 3 plane formats anyway). Explicitly sets .pixel_order in each case, rather than relying on then default XYCBCR order being a value 0.
