drm/imx: fix YUV primary plane and IPUv3 build corner case - Enable color space conversion on the primary plane when the framebuffer format is a YUV format. - The IPUv3 base driver now uses drm_format_info in the PRE/PRG code. The PRE/PRG parts are already disabled if DRM is not available. Enforce that if DRM is built as a module, IPUv3 must be built as a module, too. * tag 'imx-drm-fixes-2017-08-18' of git://git.pengutronix.de/git/pza/linux: drm/imx: ipuv3-plane: fix YUV framebuffer scanout on the base plane gpu: ipu-v3: add DRM dependency
