2018-06-05gpio: madera: Support Cirrus Logic Madera class codecsRichard Fitzgerald1-0/+206
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.
