33 | You shouldn't need to change this unless you really need to |
34 | optimize either stack space or performance. Change this carefully | |
35 | since setting an incorrect value could cause stack corruption. | |

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

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

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