This adds support for the GPIOs on Cirrus Logic Madera class codecs. Any pins not used for special functions (see the pinctrl driver) can be used as general single-bit input or output lines. The number of available GPIOs varies between codecs. Note that this is part of a composite MFD for these codecs and can only be used with the corresponding MFD and other child drivers on those silicon. The GPIO block on these codecs does not exist indepedently of the rest of the MFD.

These checks help ensure that GPIOs have been properly initialized

before they are used, and that sleeping calls are not made from

non-sleeping contexts. They can make bitbanged serial protocols

slower. The diagnostics help catch the type of setup errors

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