Hisilicon Hi6220 SRAM controller
Required properties:
- compatible : "hisilicon,hi6220-sramctrl", "syscon"
- reg : Register address and size
Hisilicon's SoCs use sram for multiple purpose; on Hi6220 there have several
SRAM banks for power management, modem, security, etc. Further, use "syscon"
managing the common sram which can be shared by multiple modules.
Example:
/*for Hi6220*/
sram: sram@fff80000 {
compatible = "hisilicon,hi6220-sramctrl", "syscon";
reg = <0x0 0xfff80000 0x0 0x12000>;
};
