With that, We can map memory for ACPI in the same way > as DT. You are reinventing a wheel, i.e. MFD framework. Can you simple utilize devm_mfd_add_devices()? Basically you may write an new pure MFD driver (drivers/mfd) that will instantiate properly the pin control driver. -- With Best Regards, Andy Shevchenko
