 1USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.
 2
 3The GRUSBDC USB Device Controller core is available in the GRLIB VHDL
 4IP core library.
 5
 6Note: In the ordinary environment for the core, a Leon SPARC system,
 7these properties are built from information in the AMBA plug&play.
 8
 9Required properties:
10
11- name : Should be "GAISLER_USBDC" or "01_021"
12
13- reg : Address and length of the register set for the device
14
15- interrupts : Interrupt numbers for this device. Either one interrupt number
16	for all interrupts, or one for status related interrupts, one for IN
17	endpoint related interrupts and one for OUT endpoint related interrupts.
18
19Optional properties:
20
21- epobufsizes : Array of buffer sizes for OUT endpoints when they differ
22	from the default size of 1024. The array is indexed by the OUT endpoint
23	number. If the property is present it typically contains one entry for
24	each OUT endpoint of the core. Fewer entries overrides the default sizes
25	only for as many endpoints as the array contains.
26
27- epibufsizes : Array of buffer sizes for IN endpoints when they differ
28	from the default size of 1024. The array is indexed by the IN endpoint
29	number. If the property is present it typically contains one entry for
30	each IN endpoint of the core. Fewer entries overrides the default sizes
31	only for as many endpoints as the array contains.
