SRAM bindings for various SoCs, using the mmio-sram genalloc API, are spread over different places - per SoC vendor. Since all of these are quite similar (they depend on mmio-sram) move them to a common place.

Rockchip SRAM for pmu:
|
|
------------------------------
|
|
|
|
The sram of pmu is used to store the function of resume from maskrom(the 1st
|
|
level loader). This is a common use of the "pmu-sram" because it keeps power
|
|
even in low power states in the system.
|
|
|
|
Required node properties:
|
|
- compatible : should be "rockchip,rk3288-pmu-sram"
|
|
- reg : physical base address and the size of the registers window
|
|
|
|
Example:
|
|
sram@ff720000 {
|
|
compatible = "rockchip,rk3288-pmu-sram", "mmio-sram";
|
|
reg = <0xff720000 0x1000>;
|
|
};
