Add a reset driver framework/uclass A reset controller is a hardware module that controls reset signals that affect other hardware modules or chips. This patch defines a standard API that connects reset clients (i.e. the drivers for devices affected by reset signals) to drivers for reset controllers/providers. Initially, DT is the only supported method for connecting the two. The DT binding specification (reset.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/reset/reset.txt.

config DM_RESET
bool "Enable reset controllers using Driver Model"
depends on DM && OF_CONTROL
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.
reset: implement a reset test This adds a sandbox reset implementation (provider), a test client device, instantiates them both from Sandbox's DT, and adds a DM test that excercises everything. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

doing anything beyond a little error checking.
reset: Add STi reset support This patch adds a reset controller implementation for STMicroelectronics STi family SoCs; it allows a group of related reset like controls found in multiple system configuration registers to be represented by a single controller device.

dm: reset: add stm32 reset driver This driver is adapted from linux drivers/reset/reset-stm32.c It's compatible with STM32 F4/F7/H7 SoCs. This driver doesn't implement .of_match as it's binded by MFD RCC driver. To add support for each SoC family, a SoC's specific include/dt-binfings/mfd/stm32xx-rcc.h file must be added. This patch only includes stm32h7-rcc.h dedicated for STM32H7 SoCs. Other SoCs support will be added in the future.

reset: implement a driver for the Tegra CAR Implement a reset uclass driver for the Tegra CAR. This allows clients to use standard reset APIs on Tegra. This device is intended to be instantiated by the core Tegra CAR driver, rather than being instantiated directly from DT. The implementation uses the existing custom Tegra- specific reset APIs to avoid coupling the series with significant refactoring of the existing Tegra clock/reset code.

reset: add Tegra186 reset driver In Tegra186, on-SoC reset signals are manipulated using IPC requests to the BPMP (Boot and Power Management Processor).

reset: Introduce TI System Control Interface (TI SCI) reset driver 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.
