From 8f6c6f3a23c002f5247c407205f3a62dcd0e0c8c Mon Sep 17 00:00:00 2001
From: James Feist <james.feist@linux.intel.com>
Date: Thu, 23 Apr 2020 14:01:38 -0700
Subject: [PATCH] Only allow drive sensors on bus 2 for ast2500
CPLD doesn't allow multi-master, so readings wont work.
Put in a work-around to only allow bus 2 transactions.
Tested: Only valid sensors were installed.
