[Blackfin] arch: Allow concurrent use of GPIO and GPIO IRQ 2008-04-24T00:10:10+00:00 Michael Hennerich michael.hennerich@analog.com 2008-04-24T00:10:10+00:00 affee2b2613ada262eecea354b6c60696ca5d482 The irq setup code no longer calls gpio request and free. This patch also changes the default gpio_free behavior on Blackfin. A freed GPIO keeps it's last state, and is not defaulted back to an input. This is also what all other architectures do.
