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.

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.
