Communication 16 between the host processor running an OS and the system controller happens 17 through a protocol called TI System Control Interface (TI-SCI protocol). 18 19 This reset controller node uses the TI SCI protocol to perform the reset 20 management of various hardware modules present on the SoC. Must be a child 21 node of the associated TI-SCI system controller node. 22 23properties: 24 $nodename: 25 pattern: "^reset-controller$" 26 27 compatible: 28 const: ti,sci-reset 29 30 "#reset-cells": 31 const: 2 32 description: 33 The two cells represent values that the TI-SCI controller defines. 34 35 The first cell should contain the device ID. 36 37 The second cell should contain the reset mask corresponding to the device 38 used by system controller. 39 40 Please see http://processors.wiki.ti.com/index.php/TISCI for 41 protocol documentation for the values to be used for different devices. 42 43 44additionalProperties: false 45 46examples: 47 - | 48 k3_reset: reset-controller { 49 compatible = "ti,sci-reset"; 50 #reset-cells = <2>; 51 };
