Subject: [PATCH 09/11] OMAP2+: l3-noc: Add support for device-tree
Date: Fri, 23 Sep 2011 22:23:17 +0200 [thread overview]
Message-ID: <1316809399-19579-10-git-send-email-b-cousson@ti.com> (raw)
In-Reply-To: <1316809399-19579-1-git-send-email-b-cousson@ti.com>
Add device-tree support for the l3-noc driver.
Use platform_driver_register to defer the probing at device init
time.
Add documentation for the l3-noc bindings.

+This version is an implementation of the generic NoC IP

+- compatible : Should be "ti,omap3-l3-smx" for OMAP3 family
+ Should be "ti,omap4-l3-noc" for OMAP4 family
+- ti,hwmods: "l3_main_1", ... One hwmod for each noc domain.

+ #size-cells = <1>;
+ ranges;
