+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>;
++			hback-porch = <39>;
++			hsync-len = <47>;

+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).

+The platform_quirk element in the platform data was used to change the
+way the IRQ is triggered.  When set, the EDGE_IRQ quirk would change
+the irqflags used and treat edge trigger differently from the rest.
+
+Instead of hiding this irq flag setting behind the quirk, have the
+board files set the flags during initialization.  This will be more
+meaningful than driver-specific quirks when we switch to DT.
+
+Additionally, fix missing gpio_request() calls in the boarding files
+(so that setting the flags actually works).

+Add refclock and tcxoclock as clock providers in WiLink.  These clocks

+In theory, the WiLink chip could be connected to external clocks

+code generic enough.  If external clocks are used, then the internal
+clock device tree nodes are not necessary, but the external ones must

++TI WiLink Wireless Modules Device Tree Bindings
++===============================================
++
++The WiLink modules provide wireless connectivity, such as WLAN,
++Bluetooth, FM and NFC.
++
++There are several different modules available, which can be grouped by
++their generation: WiLink6, WiLink7 and WiLink8.  WiLink4 is not
++currently supported with device tree.
++
++Currently, only the WLAN portion of the modules is supported with
++device tree.
++
++Required properties:
++--------------------
++
++- compatible: should be "ti,wilink6", "ti,wilink7" or "ti,wilink8"
++- interrupt-parent: the interrupt controller
++- interrupts: out-of-band WLAN interrupt
++	See the interrupt controller's bindings documentation for
++	detailed definition.
++
++Optional properties:
++--------------------
++
++- clocks: list of clocks needed by the chip as follows:
++
++  refclock: the internal WLAN reference clock frequency (required for
++	WiLink6 and WiLink7; not used for WiLink8).
++
++  tcxoclock: the internal WLAN TCXO clock frequency (required for
++	WiLink7 not used for WiLink6 and WiLink8).
++
++  The clocks must be defined and named accordingly.  For example:
++
++  clocks = <&refclock>
++  clock-names = "refclock";
++
++  refclock: refclock {
++		     compatible = "ti,wilink-clock";
++		     #clock-cells = <0>;
++		     clock-frequency = <38400000>;
++	};
++
++  Some modules that contain the WiLink chip provide clocks in the
++  module itself.  In this case, we define a "ti,wilink-clock" as shown
++  above.  But any other clock could in theory be used, so the proper
++  clock definition should be used.
++
++
++Example:
++--------
++
++Example definition that can be used in OMAP4 Panda:
++
++wlan {
++	compatible = "ti,wilink6";
++	interrupt-parent = <&gpio2>;
++	interrupts = <21 IRQ_TYPE_LEVEL_HIGH>;	/* gpio line 53 */
++	clocks = <&refclock>;
++	clock-names = "refclock";
++
++	refclock: refclock {
++		compatible = "ti,wilink-clock";
++		#clock-cells = <0>;
++		clock-frequency = <38400000>;
++	};
++};
