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. System configuration registers are accessed through the regmap framework and the mfd/syscon driver. The implementation optionally supports waiting for the reset action to be acknowledged in a separate status register and supports both active high and active low reset lines. These properties are common across all the reset channels in a specific reset controller instance, hence all channels in a paritcular controller are expected to behave in the same way.

Generic Reset Controller support.

This framework is designed to abstract reset handling of devices

|
via GPIOs or SoC-internal reset controller modules.
