Subject: [PATCH 04/13] ARM: dts: omap4: Add IPU DT node
Date: Thu, 9 Jul 2020 18:19:45 -0500
Message-ID: <20200709231954.1973-5-s-anna@ti.com> (raw)
In-Reply-To: <20200709231954.1973-1-s-anna@ti.com>

The DT node for the Dual-Cortex M3 IPU processor sub-system has
been added for OMAP4 SoCs. The L2RAM memory region information
has been added to the node through the 'reg' and 'reg-names'
properties. The node has the 'iommus', 'clocks', 'resets',
'mboxes' and 'firmware' properties also added, and is disabled
for now. It should be enabled as per the individual product
configuration in the corresponding board dts files.
