This driver can also be built as module (exynos_chipid). config EXYNOS_USI tristate "Exynos USI (Universal Serial Interface) driver" default ARCH_EXYNOS && ARM64 depends on ARCH_EXYNOS || COMPILE_TEST select MFD_SYSCON help Enable support for USI block. USI (Universal Serial Interface) is an IP-core found in modern Samsung Exynos SoCs, like Exynos850 and ExynosAutoV9. USI block can be configured to provide one of the following serial protocols: UART, SPI or High Speed I2C. This driver allows one to configure USI for desired protocol, which is usually done in USI node in Device Tree. config EXYNOS_PMU bool "Exynos PMU controller driver" if COMPILE_TEST depends on ARCH_EXYNOS || ((ARM || ARM64) && COMPILE_TEST) select EXYNOS_PMU_ARM_DRIVERS if ARM && ARCH_EXYNOS select MFD_CORE # There is no need to enable these drivers for ARMv8 config EXYNOS_PMU_ARM_DRIVERS bool "Exynos PMU ARMv7-specific driver extensions" if COMPILE_TEST depends on EXYNOS_PMU config EXYNOS_PM_DOMAINS bool "Exynos PM domains" if COMPILE_TEST depends on (ARCH_EXYNOS && PM_GENERIC_DOMAINS) || COMPILE_TEST config SAMSUNG_PM_DEBUG bool "Samsung PM Suspend debug" depends on PM && DEBUG_KERNEL depends on PLAT_S3C24XX || ARCH_S3C64XX || ARCH_S5PV210 depends on DEBUG_S3C24XX_UART || DEBUG_S3C2410_UART depends on DEBUG_LL && MMU help Say Y here if you want verbose debugging from the PM Suspend and Resume code.

This option will generate CRCs of all blocks of memory, and store them before going to sleep. The blocks are then checked on resume for any errors. Note, this can take several seconds depending on memory size and CPU speed.

A smaller value will mean that the CRC data block will take more memory, but will identify any faults with better precision.
