| title: TI-SCI reset controller |

| description: | |
| 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). |
| |
| 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. |

| description: |
| The two cells represent values that the TI-SCI controller defines. |
| |
| The first cell should contain the device ID. |
| |
| The second cell should contain the reset mask corresponding to the device |
| used by system controller. |
| |
| Please see http://processors.wiki.ti.com/index.php/TISCI for |
| protocol documentation for the values to be used for different devices. |
