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