From: Grant Likely <grant.likely at secretlab.ca>

Here's my second version of xilinx device tree bindings.  Please review
and comment.  I'd like to push these out to Paulus in the next couple
of days.

Cheers,
g.

    More devices will be defined as this spec matures.
 
+   l) Xilinx ML300 Framebuffer
+
+   Simple framebuffer device from the ML300 reference design (also on the
+   ML403 reference design as well as others).
+
+   Required properties:
+    - compatible : Must include "xilinx,ml300-fb"
+    - reg : offset and length of the framebuffer register set
+
+   Optional properties:
+    - resolution : <xres yres> pixel resolution of framebuffer.  Some
+                   implementations use a different resolution.  Default
+                   is <d#640 d#480>
+    - virt-resolution : <xvirt yvirt> Size of framebuffer in memory.
+                        Default is <d#1024 d#480>.
+    - rotate-display (empty) : rotate display 180 degrees.
+
+   m) Xilinx SystemACE
+
+   The Xilinx SystemACE device is used to program FPGAs from an FPGA
+   bitstream stored on a CF card.  It can also be used as a generic CF
+   interface device.
+
+   Required properties:
+    - compatible : Must include "xilinx,sysace"
+    - reg : offset and length of SystemACE register set
+
+   Recommended properties:
+    - interrupt-parent, interrupts : Connection of device irq signal.
+
+   Optional properties:
+    - 8-bit (empty) : Set this property if the SystemACE must be in 8 bit mode
+
+   n) Xilinx EMAC and Xilinx TEMAC
+
+   Xilinx Ethernet devices.  Uses common properties from other Ethernet
+   devices with the following constraints:
+   
+   Required properties:
+    - compatible : Must include one of: "xilinx,plb-temac",
+                   "xilinx,plb-emac", "xilinx-opb-emac"
+    - dma-mode : Must be one of "none", "simple", "sg" (sg == scatter gather)
+
+   o) Xilinx Uartlite
+
+   Xilinx uartlite devices are simple fixed speed serial ports.  Uartlite
+   ports should be described in a node with the following properties.
+
+   Requred properties:
+    - compatible : Must include "xilinx,uartlite"
+    - reg : offset and length of uartlite register set
+
+    Recommended properties:
+    - interrupt-parent, interrupts : Connection of device irq signal.
