From ae5b3671b39f26b79685496d79845f9a4f3975db Mon Sep 17 00:00:00 2001 From: Richard Spiegel Date: Wed, 19 Jun 2019 13:57:55 -0700 Subject: superio/fintek: Add f81803A Add f81803A plus the capability to control the fan with any fintek SIO. This will be done through a common API, though currently only F81803A will have it implemented. BUG=none. TEST=Tested later with padmelon board.
