Subject: [PATCH 129/703] gpiolib: Don't prevent IRQ usage of output GPIOs
|
|
|
|
Upstream Linux deems using output GPIOs to generate IRQs as a bogus
|
|
use case, even though the BCM2835 GPIO controller is capable of doing
|
|
so. A number of users would like to make use of this facility, so
|
|
disable the checks.
|
|
|
|
