serial: 8250: add IRQ trigger support
There is currently no provision for passing IRQ trigger flags for serial IRQs with triggering requirements (such as GPIO IRQs) This patch adds irqflags to plat_serial8250_port that can be passed from board file to reqest_irq() of 8250 driver Changes are backward compatible with boards passing UPF_SHARE_IRQ flag Tested on Zoom2 board that has IRQF_TRIGGER_RISING requirement for 8250 irq [Moved new flag to end to fix bugs in the original with the old_serial array -- Alan] Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
