16 | Select this config option from the architecture Kconfig, if | |
17 | it is possible to use gpiolib on the architecture, but let the | |
18 | user decide whether to actually build it or not. | |
19 | Select this instead of ARCH_REQUIRE_GPIOLIB, if your architecture does | |
20 | not depend on GPIOs being available, but rather let the user | |
21 | decide whether he needs it or not. | |

66 | Say Y here to add some extra checks and diagnostics to GPIO calls. | |

67 | These checks help ensure that GPIOs have been properly initialized |

69 | non-sleeping contexts. They can make bitbanged serial protocols | |

77 | Say Y here to add a sysfs interface for GPIOs. | |
78 | ||
79 | This is mostly useful to work around omissions in a system's | |
80 | kernel support. Those are common in custom and semicustom | |
81 | hardware assembled using standard kernels with a minimum of | |
82 | custom patches. In those cases, userspace code may import | |
83 | a given GPIO from the kernel, if no kernel driver requested it. | |
84 | ||
85 | Kernel drivers may also request that a particular GPIO be | |
86 | exported to userspace; this can be useful when debugging. | |
