18

19

20
+	  different frequency. The timings are calculated based on DT memory
21

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
31

32
