[PATCH 0/2] gpio-f7188x: Add F81886 gpio function

From: Peter Hung
Date: Tue Jan 12 2016 - 02:42:22 EST


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.
