Subject: [PATCH] lasips2: introduce port IRQ and new lasips2_port_init()
function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Introduce a new lasips2_port_init() QOM init function for the LASIPS2_PORT type
and use it to initialise a new gpio for use as a port IRQ. Add a new qemu_irq
representing the gpio as a new irq field within LASIPS2Port.
