drm: Renesas SH Mobile DRM driver The SH Mobile LCD controller (LCDC) DRM driver supports the main graphics plane in RGB and YUV formats, as well as the overlay planes (in alpha-blending mode only). Only flat panel outputs using the parallel interface are supported. Support for SYS panels, HDMI and DSI is currently not implemented.

depends on DRM && ARM && HAVE_DMA_ATTRS
drm/shmobile: Add run-time dependencies The shmobile DRM driver is only useful on SuperH and shmobile unless build testing. I am dropping the SuperH dependencies though because the driver doesn't even build there, so in practice it is an arm-only driver for now.

depends on ARCH_SHMOBILE || COMPILE_TEST
drm: shmobile: fix Kconfig dependencies The shmobile drm driver selects BACKLIGHT_CLASS_DEVICE as of 0a5a5499ad88 "drm: shmobile: Add dependency on BACKLIGHT_CLASS_DEVICE", but that option in turn depends on BACKLIGHT_LCD_SUPPORT, so we actually have to select both, or alternatively use 'depends on BACKLIGHT_CLASS_DEVICE'. Further, the driver uses FB_SH_MOBILE_MERAM if that is enabled, but this breaks if MERAM is a module while the DRM driver is built-in. To solve this, add a dependency on "FB_SH_MOBILE_MERAM || !FB_SH_MOBILE_MERAM", which forces DRM_SHMOBILE to be a module if FB_SH_MOBILE_MERAM set to 'm'.

select DRM_KMS_HELPER
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.

Choose this option if you have an SH Mobile chipset.
If M is selected the module will be called shmob-drm.
