Hi, This series adds a check for detecting the IRQ trigger type mismatch between the platform (DT) and a device driver. Currently, if there is a mismatch, there is no error thrown but the driver requested trigger gets set silently. Then during the second time probe of a driver (due to probe defer or rmmod/insmod), platform_get_irq() throws a warning similar to below and fails. irq: type mismatch, failed to map hwirq-9 for interrupt-controller@b220000! But ideally, during the first time itself, request_irq() should've failed as the flag mismatch is a hard error. So let's add a check in __setup_irq(), such that the request_irq() would fail if a mismatch has been detected. NOTE: This might break platforms those has the flag set incorrectly in DT. One of such case is SDX55, where the UART node has the trigger set incorrectly. I fixed it in a couple of places I happen to know. But there could be many...
