Subject: adding external interrupt support for MPC8313e bsp
Date: Thu, 22 May 2008 16:41:18 -0400 [thread overview]
Message-ID: <4835DA6E.2020709@ntigo.com> (raw)
Hi,
I have mpc8313e local bus connected to a external UART. and the
interrupt is connected to EXT_INT2.
I am able to communicate to UART if I disable IRQ i.e IRQ = 0 in port
structure.
I am not able to understand how to tell kernel to use external IRQ -2.
Should I put the external interrupts in device tree and if so how?
or can I use the interrupt directly in the driver and in that case do I
need to map the interrupt.
Any help or pointer is highly appreciated.
Thanks in advance.
Suvidh
