gpio-f7188x: Add F81866 GPIO supports
Add F81866 GPIO supports
Fintek F81866 is a SuperIO. It contains HWMON/GPIO/Serial Ports.
and it has totally 72(9x8 sets) gpio pins.
Here is the PDF spec:
http://www.alldatasheet.com/datasheet-pdf/pdf/459085/FINTEK/F81866AD-I.html
The control method is the same with F7188x, but we should care the address
of GPIO8x.
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.
