Some TI Keystone 2 and K3 family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and the Device Management and Security Controller on AM65x SoCs) that manage the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a reset driver that communicates to the system controller over the TI SCI protocol for performing reset management of various devices present on the SoC. Various reset functionalities are achieved by the means of different TI SCI device operations provided by the TI SCI framework. This code is loosely based on the drivers/reset/reset-ti-sci.c driver of the Linux kernel.

help
|
|
Enable support for the reset controller driver class. Many hardware
|
|
modules are equipped with a reset signal, typically driven by some
|
|
reset controller hardware module within the chip. In U-Boot, reset
|
|
controller drivers allow control over these reset signals. In some
|
|
cases this API is applicable to chips outside the CPU as well,
|
|
although driving such reset isgnals using GPIOs may be more
|
|
appropriate in this case.
