+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>;

+Subject: [PATCH 752/752] video/da8xx-fb fix defect with vsync callback
+ invocation
+
+Fix defect where SGX is running at half of the expected framerate.
+The original patch (@ commit ID 9a1a810516ae9cb3259b898b6879901c5b44fa90)
+seems to have a mistake where it only calls the callback
+for the even or the odd frames depending on the revision of the LCD controller
+This patch corrects this and invokes the callback for both odd and even frame
+for just the Rev02 version of the LCDC (won't find an SGX GPU on a Rev01).
