From aca429ff9d14f0f55f6d319d6bb1dfc2bbee09fe Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 21 May 2018 11:00:02 +0100 Subject: gpio: madera: Support Cirrus Logic Madera class codecs 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.
