Laurent Pinchart f3bda362b5 drm: rcar-du: Add dependency on OF
The driver requires OF support, add a dependency in Kconfig and remove
the platform_device_id table that isn't used anymore.

Chen Gang S db88c8f4e7 drm: Kconfig: Let all DRM_GEM_CMA_HELPER related macros depend on HAVE_DMA_ATTRS
DRM_GEM_CMA_HELPER is depend on HAVE_DMA_ATTRS, or it will break the
building. The related error (with allmodconfig under xtensa):

Laurent Pinchart 637e6194e0 drm: rcar-du: Add HDMI encoder and connector support
SoCs that integrate the DU have no internal HDMI encoder, support
external encoders only.

Laurent Pinchart 1d46fea7d0 drm/rcar-du: Use struct videomode in platform data
In preparation for DT support where panel timings will be described by a
DRM-agnostic video mode, replace the struct drm_mode_modeinfo instance
in the panel platform data with a struct videomode.

Jean Delvare 923d941990 drm/rcar-du: Add run-time dependencies
The Renesas R-Car Display Unit driver is only useful on shmobile
unless build testing. The LVDS output is useful on an even more
reduced hardware set.

Daniel Vetter 92b6f89f6b drm: Add separate Kconfig option for fbdev helpers
For drivers which might want to disable fbdev legacy support.

Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.

v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm
driver can already take advantage of this, which allows us to build
msm without any fbdev depencies in the kernel!

v3: Move the MODULE_* stuff from the fbdev helper file to
drm_crtc_helper.c.

Laurent Pinchart 4bf8e1962f drm: Renesas R-Car Display Unit DRM driver
The R-Car Display Unit (DU) DRM driver supports both superposition
processors and all eight planes in RGB and YUV formats with alpha
blending.

Only VGA and LVDS encoders and connectors are currently supported.
