-Texas Instruments System Control Interface (TI-SCI) Reset Controller
-=====================================================================
-
-Some TI SoCs contain a system controller (like the Power Management Micro
-Controller (PMMC) on Keystone 66AK2G SoC) that are responsible for controlling
-the state of the various hardware modules present on the SoC. Communication
-between the host processor running an OS and the system controller happens
-through a protocol called TI System Control Interface (TI-SCI protocol).
-For TI SCI details, please refer to the document,
-Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
-
-TI-SCI Reset Controller Node
-============================
-This reset controller node uses the TI SCI protocol to perform the reset
-management of various hardware modules present on the SoC. Must be a child
-node of the associated TI-SCI system controller node.
-
-Required properties:
---------------------
- - compatible : Should be "ti,sci-reset"
- - #reset-cells : Should be 2. Please see the reset consumer node below for
- usage details.
-
-TI-SCI Reset Consumer Nodes
-===========================
-Each of the reset consumer nodes should have the following properties,
-in addition to their own properties.
-
-Required properties:
---------------------
- - resets : A phandle and reset specifier pair, one pair for each reset
- signal that affects the device, or that the device manages.
- The phandle should point to the TI-SCI reset controller node,
- and the reset specifier should have 2 cell-values. The first
- cell should contain the device ID. The second cell should
- contain the reset mask value used by system controller.
- Please refer to the protocol documentation for these values
- to be used for different devices,
- http://processors.wiki.ti.com/index.php/TISCI#66AK2G02_Data
-
-Please also refer to Documentation/devicetree/bindings/reset/reset.txt for
-common reset controller usage by consumers.
-
-Example:
---------
-The following example demonstrates both a TI-SCI reset controller node and a
-consumer (a DSP device) on the 66AK2G SoC.
-
-pmmc: pmmc {
- compatible = "ti,k2g-sci";
-
- k2g_reset: reset-controller {
- compatible = "ti,sci-reset";
- #reset-cells = <2>;
- };
-};
-
-dsp0: dsp@10800000 {
- ...
- resets = <&k2g_reset 0x0046 0x1>;
- ...
-};
