drivers: reset: STi SoC system configuration reset controller 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. 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.

reset: Add a reset controller driver for the Lantiq XWAY based SoCs The reset controllers (on xRX200 and newer SoCs have two of them) are provided by the RCU module. This was initially implemented as a simple reset controller. However, the RCU module provides more functionality (ethernet GPHYs, USB PHY, etc.), which makes it a MFD device. The old reset controller driver implementation from arch/mips/lantiq/xway/reset.c did not honor this fact. For some devices the request and the status bits are different.

reset: Add the TI SCI reset driver Some TI Keystone family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G 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. Signed-off-by: Andrew F.
