-Subject: [PATCH 334/752] video: da8xx-fb: adding dt support
-
-Enhancing driver to enable probe triggered by a corresponding dt entry.
-
-Add da8xx-fb.txt documentation to devicetree section.
-
-Obtain fb_videomode details for the connected lcd panel using the
-display timing details present in DT.
-
-Ensure that platform data is present before checking whether platform
-callback is present (the one used to control backlight). So far this
-was not an issue as driver was purely non-DT triggered, but now DT
-support has been added this check must be performed.
-
-v2: squashing multiple commits from Afzal Mohammed (afzal@ti.com)
-v3: remove superfluous cast
-v4: expose both ti,am3352-lcdc and ti,da830-lcdc for .compatible
-	as driver can use enhanced features of all version of the
-	silicon block.
-v5: addressed review comments from Prabhakar Lad
-v6: Changed the .compatible naming to match the existing drm bindings
-	for am33xx devices
-v7: clarify which compatible to use in the documentation for DA850
-

-+TI LCD Controller on DA830/DA850/AM335x SoC's
-+
-+Required properties:
-+- compatible:
-+	DA830, DA850 - "ti,da8xx-tilcdc"
-+	AM335x SoC's - "ti,am33xx-tilcdc"
-+- reg: Address range of lcdc register set
-+- interrupts: lcdc interrupt
-+- display-timings: typical videomode of lcd panel, represented as child.
-+  Refer Documentation/devicetree/bindings/video/display-timing.txt for
-+  display timing binding details. If multiple videomodes are mentioned
-+  in display timings node, typical videomode has to be mentioned as the
-+  native mode or it has to be first child (driver cares only for native
-+  videomode).
-+
-+Recommended properties:
-+- ti,hwmods: Name of the hwmod associated to the LCDC
-+
-+Example for am335x SoC's:
-+
-+lcdc@4830e000 {
-+	compatible = "ti,am33xx-tilcdc";
-+	reg =  <0x4830e000 0x1000>;
-+	interrupts = <36>;
-+	ti,hwmods = "lcdc";
-+	status = "okay";
-+	display-timings {
-+		800x480p62 {
-+			clock-frequency = <30000000>;
-+			hactive = <800>;
-+			vactive = <480>;
-+			hfront-porch = <39>;
