+Binding for Xylon FB driver
+
+Xylon FB driver supports Xylon configurable video controller
+logiCVC FPGA IP core device.
+
+Required properties:
+ - compatible: value must be "xylon,fb-3.00.a"
+ - clocks: the phandle for the pixel clock generator
+ - device: the phandle for logiCVC video controller device
+ - encoder: the phandle for the video encoder
+
+Optional properties:
+ - console-layer: layer ID for FB console (0 - 4)
+ If omitted, FB console started on default layer ID 0.
+ Note: FB console can be started only on layer configured with one
+ of parameters combination below:
+ ===================
+ bits-per-pixel type transparency
+ ===================
+ 8 yuv clut32
+ 8 rgb clut16
+ 8 rgb clut32
+ 8 rgb layer
+ 16 rgb layer
+ 32 rgb layer
+ 32 rgb pixel
+ ===================
+
+ - edid-video-mode: video mode set to preferred EDID resolution
+ If omitted, configured according to "video-mode" property.
+ - edid-print: prints EDID description in system log
+ Must be used only with "edid-video-mode".
+ If omitted, functionality is not available.
+ - vsync-irq: generate interrupt on vertical synchronization pulse
+ - video-mode: preferred video mode resolution
+ If omitted, configures logiCVC to default video resolution "1024x768".
+ - M: Coordinated Video Timings (CVT)
+ - R: reduced video timings for digital displays
+ - i: calculate for an interlaced mode
+ - m: add margins to calculation calculation
+ (1.8% of xres rounded down to 8 pixels and 1.8% of yres).
+Example:
+
+ xylon_fb {
+ compatible = "xylon,fb-3.00.a";
+ clocks = <&si570>;
+ device = <&logicvc_0>;
+ encoder = <&adv7511>;
+ console-layer = <0>;
+ edid-video-mode;
+ edid-print;
+ vsync-irq;
+ video-mode = "1920x1080MR";
+ };
