From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- Documentation/devicetree/bindings/arm/omap/dsp.txt | 14 +++++++ .../devicetree/bindings/arm/omap/intc.txt | 27 ++++++++++++ Documentation/devicetree/bindings/arm/omap/iva.txt | 19 +++++++++ .../devicetree/bindings/arm/omap/l3-noc.txt | 19 +++++++++ Documentation/devicetree/bindings/arm/omap/mpu.txt | 27 ++++++++++++ .../devicetree/bindings/arm/omap/omap.txt | 49 ++++++++++++++++++++++ 6 files changed, 155 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/omap/dsp.txt create mode 100644 Documentation/devicetree/bindings/arm/omap/intc.txt create mode 100644 Documentation/devicetree/bindings/arm/omap/iva.txt create mode 100644 Documentation/devicetree/bindings/arm/omap/l3-noc.txt create mode 100644 Documentation/devicetree/bindings/arm/omap/mpu.txt create mode 100644 Documentation/devicetree/bindings/arm/omap/omap.txt (limited to 'Documentation/devicetree/bindings/arm/omap') diff --git a/Documentation/devicetree/bindings/arm/omap/dsp.txt b/Documentation/devicetree/bindings/arm/omap/dsp.txt new file mode 100644 index 00000000..d3830a32 --- /dev/null +++ b/Documentation/devicetree/bindings/arm/omap/dsp.txt @@ -0,0 +1,14 @@ +* TI - DSP (Digital Signal Processor) + +TI DSP included in OMAP SoC + +Required properties: +- compatible : Should be "ti,omap3-c64" for OMAP3 & 4 +- ti,hwmods: "dsp" + +Examples: + +dsp { + compatible = "ti,omap3-c64"; + ti,hwmods = "dsp"; +}; diff --git a/Documentation/devicetree/bindings/arm/omap/intc.txt b/Documentation/devicetree/bindings/arm/omap/intc.txt new file mode 100644 index 00000000..f2583e6e --- /dev/null +++ b/Documentation/devicetree/bindings/arm/omap/intc.txt @@ -0,0 +1,27 @@ +* OMAP Interrupt Controller + +OMAP2/3 are using a TI interrupt controller that can support several +configurable number of interrupts. + +Main node required properties: + +- compatible : should be: + "ti,omap2-intc" +- interrupt-controller : Identifies the node as an interrupt controller +- #interrupt-cells : Specifies the number of cells needed to encode an + interrupt source.
