[PATCH v2 1/2] drm_fourcc: Add new P010, P016 video format

From: Randy Li
Date: Wed Jan 04 2017 - 11:29:50 EST


P010 is a planar 4:2:0 YUV with interleaved UV plane, 10 bits
per channel video format. Rockchip's vop support this
video format(little endian only) as the input video format.

P016 is a planar 4:2:0 YUV with interleaved UV plane, 16 bits
per channel video format.
