Matt LaPlante692105b2009-01-26 11:12:25 +010067 These checks help ensure that GPIOs have been properly initialized
68 before they are used, and that sleeping calls are not made from
69 non-sleeping contexts. They can make bitbanged serial protocols

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.

Masanari Iidae41e85c2012-11-30 16:44:39 +0900720 of two, so the controller will need to accommodate for that. For
Thierry Reding5e969a42012-09-18 10:57:10 +0200721 example: if a controller provides 48 pins, 6 registers will be
722 enough to represent all pins, but the driver will assume a
