Generic Reset Controller support.
This framework is designed to abstract reset handling of devices
via GPIOs or SoC-internal reset controller modules.
If unsure, say no.
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.

arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGA Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.
