17 | it is possible to use gpiolib on the architecture, but let the | |

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

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

69 | This is mostly useful to work around omissions in a system's | |
70 | kernel support. Those are common in custom and semicustom | |
71 | hardware assembled using standard kernels with a minimum of | |
72 | custom patches. In those cases, userspace code may import | |
73 | a given GPIO from the kernel, if no kernel driver requested it. | |
74 | ||
75 | Kernel drivers may also request that a particular GPIO be | |
76 | exported to userspace; this can be useful when debugging. | |
