I'd expect to see just use platform_get_irq() here and this seems to be the only DT dependency in the driver.
I copied it from spi-bcm2835.c, where it is also used in exactly that fashion. You want me to move to your recommended api instead for both drivers?

Same copy/paste in this case - i can change the order for both drivers if you want. Martin -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
