Subject: [PATCH v2 2/3] gpio: sim: make gpio simulator can be used as interrupt controller

From: Wei Yongjun <weiyongjun1@...wei.com>

Some devices using GPIO as interrupt controller, such as mcp2515 CAN
device. To mockup those devices, gpio simulator should extend to be
used as interrupt controller form device tree.
