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>;
|
||||
};
