1*4882a593SmuzhiyunUSB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe GRUSBDC USB Device Controller core is available in the GRLIB VHDL
4*4882a593SmuzhiyunIP core library.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunNote: In the ordinary environment for the core, a Leon SPARC system,
7*4882a593Smuzhiyunthese properties are built from information in the AMBA plug&play.
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunRequired properties:
10*4882a593Smuzhiyun
11*4882a593Smuzhiyun- name : Should be "GAISLER_USBDC" or "01_021"
12*4882a593Smuzhiyun
13*4882a593Smuzhiyun- reg : Address and length of the register set for the device
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun- interrupts : Interrupt numbers for this device. Either one interrupt number
16*4882a593Smuzhiyun	for all interrupts, or one for status related interrupts, one for IN
17*4882a593Smuzhiyun	endpoint related interrupts and one for OUT endpoint related interrupts.
18*4882a593Smuzhiyun
19*4882a593SmuzhiyunOptional properties:
20*4882a593Smuzhiyun
21*4882a593Smuzhiyun- epobufsizes : Array of buffer sizes for OUT endpoints when they differ
22*4882a593Smuzhiyun	from the default size of 1024. The array is indexed by the OUT endpoint
23*4882a593Smuzhiyun	number. If the property is present it typically contains one entry for
24*4882a593Smuzhiyun	each OUT endpoint of the core. Fewer entries overrides the default sizes
25*4882a593Smuzhiyun	only for as many endpoints as the array contains.
26*4882a593Smuzhiyun
27*4882a593Smuzhiyun- epibufsizes : Array of buffer sizes for IN endpoints when they differ
28*4882a593Smuzhiyun	from the default size of 1024. The array is indexed by the IN endpoint
29*4882a593Smuzhiyun	number. If the property is present it typically contains one entry for
30*4882a593Smuzhiyun	each IN endpoint of the core. Fewer entries overrides the default sizes
31*4882a593Smuzhiyun	only for as many endpoints as the array contains.
