[GIT PULL] imx-drm fixes for YUV primary plane and partially modular build

[Philipp Zabel]

Hi Dave,

This tag contains a fix to enable color space conversion for for YUV
format framebuffers on the primary plane and a Kconfig fix to avoid
a build failure. The build failure happened when DRM was built as a
module, but IMX_IPUV3_CORE was built-in. With the fix, if DRM is built
as a module, IMX_IPUV3_CORE is not allowed to be built-in anymore.

regards
Philipp

  drm/imx: ipuv3-plane: fix YUV framebuffer scanout on the base plane (2017-08-11 10:31:13 +0200)

----------------------------------------------------------------
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.
