Subject: [PATCH 3/4] spi: spi-altera-dfl: support n5010 feature revision
Date: Mon, 21 Jun 2021 09:06:20 +0200 [thread overview]
Message-ID: <20210621070621.431482-4-mhu@silicom.dk> (raw)
In-Reply-To: <20210621070621.431482-1-mhu@silicom.dk>
The Max10 BMC on the Silicom n5010 PAC is slightly different than the
existing BMC's, so use a dedicated feature revision detect it.
