1 * Rockchip General Register Files (GRF)
3 The general register file will be used to do static set by software, which
4 is composed of many registers for system control.
6 From RK3368 SoCs, the GRF is divided into two sections,
7 - GRF, used for general non-secure system,
8 - SGRF, used for general secure system,
9 - PMUGRF, used for always on system
13 - compatible: GRF should be one of the following:
14 - "rockchip,rk3036-grf", "syscon": for rk3036
15 - "rockchip,rk3066-grf", "syscon": for rk3066
16 - "rockchip,rk3188-grf", "syscon": for rk3188
17 - "rockchip,rk3228-grf", "syscon": for rk3228
18 - "rockchip,rk3288-grf", "syscon": for rk3288
19 - "rockchip,rk3368-grf", "syscon": for rk3368
20 - "rockchip,rk3399-grf", "syscon": for rk3399
21 - compatible: PMUGRF should be one of the following:
22 - "rockchip,rk3368-pmugrf", "syscon": for rk3368
23 - "rockchip,rk3399-pmugrf", "syscon": for rk3399
24 - compatible: SGRF should be one of the following
25 - "rockchip,rk3288-sgrf", "syscon": for rk3288
26 - reg: physical base address of the controller and length of memory mapped
