XDMA_EVENT_INTR1 handler question

Adrian Hart

Hello,

I want to register an interrupt handler on XDMA_EVENT_INTR1, do i just need to use this as the first argument in the function call to request_irq() in a linux driver -

assuming I've setup the pinmux correctly for this in our hardware which is based on the reference design of the AM335 evm.

Thanks,

XDMA_EVENT_INTR1 itself is not any interrupt. However, you can use the GPIO pin (GPIO0[20]) on that line and use that as an interrupt.

You can look at drivers/mmc/host/omap_hsmmc.c file on using GPIO pins as interrupt.
