Andreas Larsson27e9dcc2013-12-23 21:25:49 +01001USB 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
Andreas Larssond9a6ef12014-03-27 16:15:54 +010015- 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.

19Optional properties:
20
Andreas Larssond9a6ef12014-03-27 16:15:54 +010021- 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.

Andreas Larssond9a6ef12014-03-27 16:15:54 +010027- 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.
