5 Support for the Memory Controller (MC) devices found on
11 tristate "Exynos5422 Dynamic Memory Controller driver"
12 depends on ARCH_EXYNOS || (COMPILE_TEST && HAS_IOMEM)
14 depends on DEVFREQ_GOV_SIMPLE_ONDEMAND
15 depends on (PM_DEVFREQ && PM_DEVFREQ_EVENT)
17 This adds driver for Exynos5422 DMC (Dynamic Memory Controller).
18 The driver provides support for Dynamic Voltage and Frequency Scaling in
19 DMC and DRAM. It also supports changing timings of DRAM running with
20 different frequency. The timings are calculated based on DT memory
24 bool "Exynos SROM controller driver" if COMPILE_TEST
25 depends on (ARM && ARCH_EXYNOS) || (COMPILE_TEST && HAS_IOMEM)
27 This adds driver for Samsung Exynos SoC SROM controller. The driver
28 in basic operation mode only saves and restores SROM registers
29 during suspend. If however appropriate device tree configuration
30 is provided, the driver enables support for external memory
32 If unsure, say Y on devices with Samsung Exynos SocS.
