Add implementation for: - pin control, group information retrieval: count, name and pins - pin muxing: - function information (count, name and groups) - mux setting - gpio control (enable, disable, set direction) - pin configuration: - pull disable - pull up/down and pull strength - debounce - any other option is treated as not supported.

driver for memory mapped GPIO functionality on Intel Baytrail
|
|
platforms. Supports 3 banks with 102, 28 and 44 gpios.
|
|
Most pins are usually muxed to some other functionality by firmware,
|
|
so only a small amount is available for gpio use.
|
|
|
|
Requires ACPI device enumeration code to set up a platform device.
