23 Support for Samsung Exynos SoC ChipID and Adaptive Supply Voltage.
24 This driver can also be built as module (exynos_chipid).

29 depends on ARCH_EXYNOS || COMPILE_TEST
32 Enable support for USI block. USI (Universal Serial Interface) is an
33 IP-core found in modern Samsung Exynos SoCs, like Exynos850 and
34 ExynosAutoV9. USI block can be configured to provide one of the
35 following serial protocols: UART, SPI or High Speed I2C.
37 This driver allows one to configure USI for desired protocol, which
38 is usually done in USI node in Device Tree.

70 Say Y here to enable the use of the SMDK LEDs on the baseboard

73 Note, this currently only works for S3C64XX based SMDK boards.

77 depends on PM && (PLAT_S3C24XX || ARCH_S3C64XX || ARCH_S5PV210)
80 Enable the PM code's memory area checksum over sleep. This option
81 will generate CRCs of all blocks of memory, and store them before
82 going to sleep. The blocks are then checked on resume for any
85 Note, this can take several seconds depending on memory size
88 See <file:Documentation/arm/samsung-s3c24xx/suspend.rst>
90 config SAMSUNG_PM_CHECK_CHUNKSIZE

92 depends on PM && SAMSUNG_PM_CHECK
95 Set the chunksize in Kilobytes of the CRC for checking memory
96 corruption over suspend and resume. A smaller value will mean that
97 the CRC data block will take more memory, but will identify any
98 faults with better precision.
