From 1920906f59652b9ac45dff69d56044a98b11233b Mon Sep 17 00:00:00 2001 From: Peter Hung Date: Fri, 22 Jan 2016 15:23:33 +0800 Subject: [PATCH] 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.
