1 Aeroflex Gaisler GRGPIO General Purpose I/O cores.
3 The GRGPIO GPIO core is available in the GRLIB VHDL IP core library.
5 Note: In the ordinary environment for the GRGPIO core, a Leon SPARC system,
6 these properties are built from information in the AMBA plug&play.
10 - name : Should be "GAISLER_GPIO" or "01_01a"
12 - reg : Address and length of the register set for the device
14 - interrupts : Interrupt numbers for this device
18 - nbits : The number of gpio lines. If not present driver assumes 32 lines.
20 - irqmap : An array with an index for each gpio line. An index is either a valid
21 index into the interrupts property array, or 0xffffffff that indicates
22 no irq for that line. Driver provides no interrupt support if not
