Subject: [PATCH 2/2] ARM: OMAP2+: Remove dmm device creation
Date: Tue, 19 Mar 2013 23:43:44 -0500 [thread overview]
Message-ID: <1363754624-5209-3-git-send-email-andy.gross@ti.com> (raw)
In-Reply-To: <1363754624-5209-1-git-send-email-andy.gross@ti.com>
Remove DMM device creation via the hwmod entry. The DMM device will
now be enumerated as part of the device tree information for the
processor.

+OMAP Dynamic Memory Manager (DMM) bindings
+
+Required properties:
+- compatible: Must be "ti,dmm" for OMAP processors containing DMM block
+- reg: Contains timer register address range (base address and length)
+- interrupts: Contains interrupt information (source, etc) for the DMM IRQ
+- ti,hwmods: Name of the hwmod associated to the counter, which is typically
+ "dmm"
+
+Example:
+
+dmm: dmm@4e000000 {
+ compatible = "ti,dmm";
+ reg = <0x4e000000 0x800>;
+ ti,hwmods = "dmm";
