1   Bindings for specific devices:
2
3      i) Xilinx ML300 Framebuffer
4
5      Simple framebuffer device from the ML300 reference design (also on the
6      ML403 reference design as well as others).
7
8      Optional properties:
9       - resolution = <xres yres> : pixel resolution of framebuffer.  Some
10                                    implementations use a different resolution.
11                                    Default is <d#640 d#480>
12       - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
13                                           Default is <d#1024 d#480>.
14       - rotate-display (empty) : rotate display 180 degrees.
15
16      v) Xilinx hwicap
17
18		Xilinx hwicap devices provide access to the configuration logic
19		of the FPGA through the Internal Configuration Access Port
20		(ICAP).  The ICAP enables partial reconfiguration of the FPGA,
21		readback of the configuration information, and some control over
22		'warm boots' of the FPGA fabric.
23
24		Required properties:
25		- xlnx,family : The family of the FPGA, necessary since the
26                      capabilities of the underlying ICAP hardware
27                      differ between different families.  May be
28                      'virtex2p', 'virtex4', or 'virtex5'.
29		- compatible : should contain "xlnx,xps-hwicap-1.00.a" or
30				"xlnx,opb-hwicap-1.00.b".
31
32      vii) Xilinx USB Host controller
33
34      The Xilinx USB host controller is EHCI compatible but with a different
35      base address for the EHCI registers, and it is always a big-endian
36      USB Host controller. The hardware can be configured as high speed only,
37      or high speed/full speed hybrid.
38
39      Required properties:
40      - xlnx,support-usb-fs: A value 0 means the core is built as high speed
41                             only. A value 1 means the core also supports
42                             full speed devices.
