drm/rockchip: vop: round_up pitches to word align
VOP pitch register is word align, need align to word. VOP_WIN0_VIR: bit[31:16] win0_vir_stride_uv Number of words of Win0 uv Virtual width bit[15:0] win0_vir_width Number of words of Win0 yrgb Virtual width ARGB888 : win0_vir_width RGB888 : (win0_vir_width*3/4) + (win0_vir_width%3) RGB565 : ceil(win0_vir_width/2) YUV : ceil(win0_vir_width/4) Signed-off-by: Mark Yao <mark.yao@rock-chips.com> Reviewed-by: Sandy huang <sandy.huang@rock-chips.com> Link: https://patchwork.freedesktop.org/patch/msgid/1501494591-7034-1-git-send-email-mark.yao@rock-chips.com
