8 | Select this config option from the architecture Kconfig, if | |
9 | it is possible to use gpiolib on the architecture, but let the | |
10 | user decide whether to actually build it or not. | |
11 | Select this instead of ARCH_REQUIRE_GPIOLIB, if your architecture does | |
12 | not depend on GPIOs being available, but rather let the user | |

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

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