* Rockchip General Register Files (GRF)
|
||
|
|
||
|
The general register file will be used to do static set by software, which
|
||
|
is composed of many registers for system control.
|
||
|
|
||
|
From RK3368 SoCs, the GRF is divided into two sections,
|
||
|
- GRF, used for general non-secure system,
|
||
|
- PMUGRF, used for always on system
|
||
|
|
||
|
Required Properties:
|
||
|
|
||
|
- compatible: GRF should be one of the followings
|
||
|
- "rockchip,rk3066-grf", "syscon": for rk3066
|
||
|
- "rockchip,rk3188-grf", "syscon": for rk3188
|
||
|
- "rockchip,rk3228-grf", "syscon": for rk3228
|
||
|
- "rockchip,rk3288-grf", "syscon": for rk3288
|
||
|
- "rockchip,rk3368-grf", "syscon": for rk3368
|
||
|
- "rockchip,rk3399-grf", "syscon": for rk3399
|
||
|
- compatible: PMUGRF should be one of the followings
|
||
|
- "rockchip,rk3368-pmugrf", "syscon": for rk3368
|
||
|
- "rockchip,rk3399-pmugrf", "syscon": for rk3399
|
||
|
- reg: physical base address of the controller and length of memory mapped
|
||
|
region.
|
||
|
|
||
|
Example: GRF and PMUGRF of RK3399 SoCs
|
||
|
|
||
|
pmugrf: syscon@ff320000 {
|
||
|
compatible = "rockchip,rk3399-pmugrf", "syscon";
|
||
|
reg = <0x0 0xff320000 0x0 0x1000>;
|
||
|
};
|
||
|
|
||
|
grf: syscon@ff770000 {
|
||
|
compatible = "rockchip,rk3399-grf", "syscon";
|
||
|
reg = <0x0 0xff770000 0x0 0x10000>;
|
||
|
};
