Subject: [PATCH 2/3] reset: simple: Enable for ASPEED systems
Date: Mon, 19 Feb 2018 17:24:37 +1030	[thread overview]
Message-ID: <20180219065438.19933-3-joel@jms.id.au> (raw)
In-Reply-To: <20180219065438.19933-1-joel@jms.id.au>

ASPEED BMC SoCs have a reset controller in the LPC IP that can be
controlled using this driver to release the UARTs from reset.

No special configuration is required, so only the compatible string is
added.
