3 bool "Samsung Exynos Memory Controller support" if COMPILE_TEST
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 Samsung Exynos5422 SoC DMC (Dynamic Memory
18 Controller). The driver provides support for Dynamic Voltage and
19 Frequency Scaling in DMC and DRAM. It also supports changing timings
20 of DRAM running with different frequency. The timings are calculated
21 based on DT memory information.
22 If unsure, say Y on devices with Samsung Exynos SoCs.
25 bool "Exynos SROM controller driver" if COMPILE_TEST
26 depends on (ARM && ARCH_EXYNOS) || (COMPILE_TEST && HAS_IOMEM)
28 This adds driver for Samsung Exynos SoC SROM controller. The driver
29 in basic operation mode only saves and restores SROM registers
30 during suspend. If however appropriate device tree configuration
31 is provided, the driver enables support for external memory
33 If unsure, say Y on devices with Samsung Exynos SoCs.
