1 USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC. 2 3 The GRUSBDC USB Device Controller core is available in the GRLIB VHDL 4 IP core library. 5 6 Note: In the ordinary environment for the core, a Leon SPARC system, 7 these properties are built from information in the AMBA plug&play. 8 9 Required 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 19 Optional 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. 32 33 For further information look in the documentation for the GLIB IP core library: 34 http://www.gaisler.com/products/grlib/grip.pdf
