However, under pressure, 20 iterations also can be insufficient for clearing all pending interrupts, leading to a panic as intr_event_handle() tries to schedule an interrupt handler not registered. Solve this by introducing a flag that is set in test mode and otherwise restores pre-r253161 behavior of uart_intr(). The approach of additionally registering uart_intr() as handler as suggested in PR 194979 is not taken as that in turn would abuse special pccard and pccbb handling code of intr_event_handle().

The latter may give us the wrong data in the failure case if shift was not zero. Remove the extra copy of uart_fdt_get_clock and uart_fdt_get_shift. While here also use OF_getencprop in uart_fdt_get_clock. Move uart_fdt_get_clock and uart_fdt_get_shift to uart_bus_fdt.c, we may not build uart_cpu_fdt.c in all configs. Fix uart_fdt_get_clock. It should have been using the cell variable passed in, not value on the stack. 2015-05-23T20:54:25Z Ian Lepore ian@FreeBSD.org 2015-05-23T20:54:25Z urn:sha1:ce1563f57045eaa1141637271a1409facff93ca5 Define new linker set, UART_FDT_CLASS_AND_DEVICE, for registering full (class and device) FDT UART.
