Subject: [PATCH v3 3/5] ARM: dts: aspeed: Add mailbox and LPC Control nodes
Date: Tue, 10 Jan 2017 20:06:38 +1100 [thread overview]
Message-ID: <20170110090640.12608-4-cyrilbur@gmail.com> (raw)
In-Reply-To: <20170110090640.12608-1-cyrilbur@gmail.com>
This reserves BMC ram for host to BMC communication required by the LPC
control driver.
As both these devices exist on the LPC bus these nodes are children of a
new LPC node
