└─>GPIO support for AMD Fusion Controller Hub (G-series SOCs)
In linux kernel since version 5.1 (release Date: 2019-05-05)  
This option enables driver for GPIO on AMD's Fusion Controller Hub,
as found on G-series SOCs (e.g. GX-412TC).

Note: This driver doesn't register itself automatically, as it
needs to be provided with platform-specific configuration.
(See e.g. CONFIG_PCENGINES_APU2.)
