Subject: [PATCH 2/6] ARM: dts: omap3: Add ocmcram node
Date: Mon, 9 May 2016 16:49:22 -0500 [thread overview]
Message-ID: <1462830566-28708-3-git-send-email-d-gerlach@ti.com> (raw)
In-Reply-To: <1462830566-28708-1-git-send-email-d-gerlach@ti.com>
Add an ocmcram node to omap3 dtsi using the mmio-sram driver to
represent the 64kb of SRAM available on omap3 and it's derivatives.
