arch/ppc/syslib/virtex_devices.c:
// 0 is LEDS_4BIT, 1 is LEDS_POSITIONS, 2 is PUSH_BUTTONS_POSITION
#define XPAR_GPIO(num) { \
.name = "xilinx_gpio", \
.id = num, \
.num_resources = 2, \
That was a 2.
If anybody wants to make a patch out of those few lines of code, I couldn't
figure out how to do this with git... But I will use a more general GPIO
approach as soon as I can put my hands on our custom card.
.resource = (struct resource[]) { \
{ \
.start = XPAR_GPIO_##num##_BASEADDR, \
.end = XPAR_GPIO_##num##_HIGHADDR, \
.flags = IORESOURCE_MEM, \
}, \
{ \
.start = XPAR_INTC_0_GPIO_##num##_VEC_ID, \
.flags = IORESOURCE_IRQ, \
}, \
}, \
}
