drivers/misc: Add basic support for ATSHA204A Crypto module This module can be found on the Turris Omnia board connected via the I2C interface. Among some cryptographic functions, the chip has a 512 bit One Time Programmable memory, 88 byte configuration memory and 512 byte general purpose memory. The Turris Omnia stores serial number and device MAC address in the OTP memory. This commit adds basic support for reading the EEPROM and also exposes the chips Random Number Generator.

rockchip: efuse: add (misc) driver for RK3399 non-secure efuse block This adds a simple driver for reading the efuse block of the RK3399. It should be easy enough to add drivers for other devices (e.g. the RK3328, RK3368, etc.) by passing the device details via driver_data. Unlike the kernel driver (using the nvmem subsystem), we don't expose the efuse as multiple named cells, but rather as a linear memory that can be read using misc_read(...). The primary use case (as of today) is the generation of a 'serial#' (and a 'cpuid#') environment variable for the RK3399-Q7 (Puma) system-on-module. Note that this adds a debug-only (i.e. only if DEBUG is defined) command 'rk3399_dump_efuses' that dumps the efuse block's content. N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to include a SoC-name (together with a comment in the function) to remind whoever adds support for additional SoCs that this function currently makes assumptions regarding the size of the fuse-box based on the RK3399. The hope is that the function is adjusted to reflect any changes resulting from generalising the driver for multiple SoCs and is then renamed.

dm: Add a system reset uclass It is common for system reset to be available at multiple levels in modern hardware. For example, an SoC may provide a reset option, and a board may provide its own reset for reasons of security or thoroughness. It is useful to be able to model this hardware without hard-coding the behaviour in the SoC or board. Also there is a distinction sometimes between resetting just the CPU (leaving GPIO state alone) and resetting all the PMICs, just cutting power. To achieve this, add a simple system reset uclass. It allows multiple devices to provide reset functionality and provides a way to walk through them, requesting a particular reset type until is it provided.
