- * 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,
- - SGRF, used for general secure system,
- - PMUGRF, used for always on system
- On RK3328 SoCs, the GRF adds a section for USB2PHYGRF,
- Required Properties:
- - compatible: GRF should be one of the following:
- - "rockchip,rk3036-grf", "syscon": for rk3036
- - "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,rk3328-grf", "syscon": for rk3328
- - "rockchip,rk3368-grf", "syscon": for rk3368
- - "rockchip,rk3399-grf", "syscon": for rk3399
- - "rockchip,rv1108-grf", "syscon": for rv1108
- - compatible: PMUGRF should be one of the following:
- - "rockchip,rk3368-pmugrf", "syscon": for rk3368
- - "rockchip,rk3399-pmugrf", "syscon": for rk3399
- - compatible: SGRF should be one of the following
- - "rockchip,rk3288-sgrf", "syscon": for rk3288
- - compatible: USB2PHYGRF should be one of the followings
- - "rockchip,rk3328-usb2phy-grf", "syscon": for rk3328
- - compatible: USBGRF should be one of the following
- - "rockchip,rv1108-usbgrf", "syscon": for rv1108
- - 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>;
- };
