Fintek F81886 SuperIO spec: http://www.alldatasheet.com/datasheet-pdf/pdf/459085/FINTEK/F81866AD-I.html The detail gpio check & configuration could be found within spec P126. It controls gpio is the same with F7188x and has max 9 set of gpios. The gpio address is below: GPIO0x based: 0xf0 GPIO1x based: 0xe0 GPIO2x based: 0xd0 GPIO3x based: 0xc0 GPIO4x based: 0xb0 GPIO5x based: 0xa0 GPIO6x based: 0x90 GPIO7x based: 0x80 GPIO8x based: 0x88 <-- not 0x70. The first patch only add basic structure for F81866 to use all unverified gpio, and second patch add filter function to make sure only enabled gpios are exported.
