USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.
|
|
|
|
The GRUSBDC USB Device Controller core is available in the GRLIB VHDL
|
|
IP core library.
|
|
|
|
Note: In the ordinary environment for the core, a Leon SPARC system,
|
|
these properties are built from information in the AMBA plug&play.
|
|
|
|
Required properties:
|
|
|
|
- name : Should be "GAISLER_USBDC" or "01_021"
|
|
|
|
- reg : Address and length of the register set for the device
|
|
|
|
- interrupts : Interrupt numbers for this device. Either one interrupt number
|
|
for all interrupts, or one for status related interrupts, one for IN
|
|
endpoint related interrupts and one for OUT endpoint related interrupts.
|
|
|
|
Optional properties:
|
|
|
|
- epobufsizes : Array of buffer sizes for OUT endpoints when they differ
|
|
from the default size of 1024. The array is indexed by the OUT endpoint
|
|
number. If the property is present it typically contains one entry for
|
|
each OUT endpoint of the core. Fewer entries overrides the default sizes
|
|
only for as many endpoints as the array contains.
|
|
|
|
- epibufsizes : Array of buffer sizes for IN endpoints when they differ
|
|
from the default size of 1024. The array is indexed by the IN endpoint
|
|
number. If the property is present it typically contains one entry for
|
|
each IN endpoint of the core. Fewer entries overrides the default sizes
|
|
only for as many endpoints as the array contains.
