+Texas Instruments FPD-Link (LVDS) Serializer
+--------------------------------------------
+
+The DS90C185 and DS90C187 are low-power serializers for portable
+battery-powered applications that reduces the size of the RGB
+interface between the host GPU and the display.
+
+Required properties:
+
+- compatible: Should be
+ "ti,ds90c185", "lvds-encoder" for the TI DS90C185 FPD-Link Serializer
+ "ti,ds90c187", "lvds-encoder" for the TI DS90C187 FPD-Link Serializer
+
+Optional properties:
+
+- powerdown-gpios: Power down control GPIO (the PDB pin, active-low)
+
+Required nodes:
+
+The devices have two video ports. Their connections are modeled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for parallel input
+- Video port 1 for LVDS output
+
+
+Example
+-------
+
+lvds-encoder {
+ compatible = "ti,ds90c185", "lvds-encoder";
+
+ powerdown-gpios = <&gpio 17 GPIO_ACTIVE_LOW>;

-This would be especially useful for tinydrm:
-
-- Add a struct drm_rect dirty_clip to drm_crtc_state. When duplicating the
- crtc state, clear that to the max values, x/y = 0 and w/h = MAX_INT, in
- __drm_atomic_helper_crtc_duplicate_state().
-
-- Move tinydrm_merge_clips into drm_framebuffer.c, dropping the tinydrm\_
- prefix ofc and using drm_fb\_. drm_framebuffer.c makes sense since this
- is a function useful to implement the fb->dirty function.
-
-- Create a new drm_fb_dirty function which does essentially what e.g.
- mipi_dbi_fb_dirty does. You can use e.g. drm_atomic_helper_update_plane as the
- template. But instead of doing a simple full-screen plane update, this new
- helper also sets crtc_state->dirty_clip to the right coordinates. And of
- course it needs to check whether the fb is actually active (and maybe where),
- so there's some book-keeping involved. There's also some good fun involved in
- scaling things appropriately. For that case we might simply give up and
- declare the entire area covered by the plane as dirty.

Fallout from atomic KMS

transport details more.
-- tinydrm_gem_cma_prime_import_sg_table should probably go into the cma
- helpers, as a _vmapped variant (since not every driver needs the vmap).
- And tinydrm_gem_cma_free_object could the be merged into

-
-- tinydrm_fb_create we could move into drm_simple_pipe, only need to add
- the fb_create hook to drm_simple_pipe_funcs, which would again simplify a
- bunch of things (since it gives you a one-stop vfunc for simple drivers).
-
- Quick aside: The unregister devm stuff is kinda getting the lifetimes of
a drm_device wrong. Doesn't matter, since everyone else gets it wrong
too :-)
-- also rework the drm_framebuffer_funcs->dirty hook wire-up, see above.
