18 All the functions that work with the descriptor-based GPIO interface are
28 gpiod_get() functions. Like many other kernel subsystems, gpiod_get() takes the

51 Both functions return either a valid GPIO descriptor, or an error code checkable
58 gpiod_get_index_optional() functions can be used. These functions return NULL
91 Device-managed variants of these functions are also defined:
126 It is strictly forbidden to use a descriptor after calling these functions.

236 Note that these functions should only be used with great moderation ; a driver
242 The following functions set the output values of an array of GPIOs:
257 The array can be an arbitrary set of GPIOs. The functions will try to set
263 The gpiod_set_array() functions take three arguments:
