Subject: [PATCH 803/806] gpio: Enable nonexclusive gpiods from DT nodes
|
|
|
|
commit ec757001c818c175e6b610e8ef80c2a25d1ed1a5 upstream.
|
|
|
|
This makes gpiod_get_from_of_node() respect the
|
|
GPIOD_FLAGS_BIT_NONEXCLUSIVE flag which is especially
|
|
nice when getting regulator GPIOs right out of device
|
|
tree nodes.
