Subject: [PATCH 14/14] arm: dts: OpenPower Palmetto system can use coprocessor for FSI
Date: Wed, 27 Jun 2018 09:26:05 +1000	[thread overview]
Message-ID: <20180626232605.13420-15-benh@kernel.crashing.org> (raw)
In-Reply-To: <20180626232605.13420-1-benh@kernel.crashing.org>

This switches away from userspace bitbanging to kernel FSI
using the coprocessor.
