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: 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.

Support for reset controller on Xilinx ZynqMP & Versal SoC's. Driver
is only passing request via Xilinx firmware interface to TF-A and PMU
reset: zynqmp: Add reset controller for ZynqMP SoC Add firmware based reset controller for Xilinx ZynqMP SoC to let other drivers to call reset functions. Driver is only tested on Xilinx ZynqMP but support for Xilinx Versal can be simply added. That's why reset_id and nr_reset are assigned in probe folder. Driver is inpired by driver from Linux kernel.

Support for TI DRA7-RESET subsystem. Basic Assert/Deassert
is supported.
reset: at91: Add reset driver for basic assert/deassert operations Add support for at91 reset controller's basic assert/deassert operations. Since this driver conflicts with the SYSRESET driver because they both bind to the same RSTC node, implement a custom bind hook that would manually bind the sysreset driver, if enabled, to the same RSTC DT node. Furthermore, delete the no longer needed compatibles from the SYSRESET driver and rename it to make sure than any possible conflicts are avoided.

config RESET_AT91
bool "Enable support for Microchip/Atmel Reset Controller driver"
depends on DM_RESET && ARCH_AT91
help
This enables the Reset Controller driver support for Microchip/Atmel
SoCs. Mainly used to expose assert/deassert methods to other drivers
that require it.
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.
