Subject: [PATCH v12 01/11] dmaengine: edma: Add TI EDMA device tree binding
Date: Thu, 20 Jun 2013 16:06:37 -0500 [thread overview]
Message-ID: <1371762407-24544-2-git-send-email-joelagnel@ti.com> (raw)
In-Reply-To: <1371762407-24544-1-git-send-email-joelagnel@ti.com>
From: Matt Porter <mdp@ti.com>
The binding definition is based on the generic DMA controller
binding.
Joel:
* Droped reserved and queue DT entries from Documentation
for now from the original patch series (v10)
* Included properties in Documentation and clarified DMA properties (V11)
* Made ti,hwmod option
* Clarified DMA entries

+TI EDMA
+
+Required properties:
+- compatible : "ti,edma3"
+- ti,edma-regions: Number of regions
+- ti,edma-slots: Number of slots
+- #dma-cells: Should be set to <1>
+ Clients should use a single channel number per DMA request.
+- dma-channels: Specify total DMA channels per CC
+- reg: Memory map for accessing module
+- interrupt-parent: Interrupt controller the interrupt is routed through
+- interrupts: Exactly 3 interrupts need to be specified in the order:
+ 1. Transfer completion interrupt.
+ 2. Memory protection interrupt.
+ 3. Error interrupt.
+Optional properties:
+- ti,hwmods: Name of the hwmods associated to the EDMA
+- ti,edma-xbar-event-map: Crossbar event to channel map
+
+Example:
+
+edma: edma@49000000 {
+ reg = <0x49000000 0x10000>;
+ interrupt-parent = <&intc>;
+ interrupts = <12 13 14>;
+ compatible = "ti,edma3";
+ ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
+ #dma-cells = <1>;
+ dma-channels = <64>;
+ ti,edma-regions = <4>;
+ ti,edma-slots = <256>;
+ ti,edma-xbar-event-map = <1 12
+ 2 13>;
