drm/tilcdc: add TI LCD Controller DRM driver (v4) A simple DRM/KMS driver for the TI LCD Controller found in various smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the CMA helpers. Currently only the TFP410 DVI encoder is supported (tested with beaglebone + DVI cape). There are also various LCD displays, for which support can be added (as I get hw to test on), and an external i2c HDMI encoder found on some boards. The display controller supports a single CRTC. And the encoder+ connector are split out into sub-devices. Depending on which LCD or external encoder is actually present, the appropriate output module(s) will be loaded. v1: original v2: fix fb refcnting and few other cleanups v3: get +/- vsync/hsync from timings rather than panel-info, add option DT max-bandwidth field so driver doesn't attempt to pick a display mode with too high memory bandwidth, and other small cleanups v4: remove some unneeded stuff from panel-info struct, properly set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Koen Kooi <koen@dominion.thruhere.net>

videomode: simplify videomode Kconfig and Makefile This patch simplifies videomode related Kconfig and Makefile. After this patch, there's only one non-user selectable Kconfig option left, VIDEOMODE_HELPERS. The reasons for the change: * Videomode helper functions are not something that should be shown in the kernel configuration options. The related code should just be included if it's needed, i.e. selected by drivers using videomode. * There's no need to have separate Kconfig options for videomode and display_timing. First of all, the amount of code for both is quite small. Second, videomode depends on display_timing, and display_timing in itself is not really useful, so both would be included in any case. * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS describes better what's included.

Choose this option if you have an TI SoC with LCDC display
controller, for example AM33xx in beagle-bone, DA8xx, or
OMAP-L1xx. This driver replaces the FB_DA8XX fbdev driver.
drm/tilcdc: Add DRM_TILCDC_SLAVE_COMPAT for ti,tilcdc,slave binding support Adds a CONFIG_DRM_TILCDC_SLAVE_COMPAT module for "ti,tilcdc,slave" node conversion. The implementation is in tilcdc_slave_compat.c and it uses tilcdc_slave_compat.dts as a basis for creating a DTS overlay. The DTS overlay adds an external tda998x encoder to tilcdc that corresponds to the old tda998x based slave encoder.

help
Choose this option if you need a kernel that is compatible
with device tree blobs using the obsolete "ti,tilcdc,slave"
binding. If you find "ti,tilcdc,slave"-string from your DTB,
you probably need this. Otherwise you do not.
