9 | the architecture to provide a custom asm/gpio.h implementation | |
10 | overriding the default implementations. New uses of this are | |

e849dc04 | 19 | one or more of the GPIO drivers below. |

44 | help | |
45 | Say Y here to add some extra checks and diagnostics to GPIO calls. | |
692105b8 ML |
46 | These checks help ensure that GPIOs have been properly initialized |
47 | before they are used, and that sleeping calls are not made from | |
48 | non-sleeping contexts. They can make bitbanged serial protocols | |
a9c5fff5 DB |

57 | ||
58 | This is mostly useful to work around omissions in a system's | |
59 | kernel support. Those are common in custom and semicustom | |
60 | hardware assembled using standard kernels with a minimum of | |
61 | custom patches. In those cases, userspace code may import | |
62 | a given GPIO from the kernel, if no kernel driver requested it. | |
63 | ||
64 | Kernel drivers may also request that a particular GPIO be | |
65 | exported to userspace; this can be useful when debugging. | |
