Pull ARM 64-bit DT updates from Olof Johansson:
"Device-tree updates for arm64 platforms. Just as with 32-bit, a bunch
of smaller changes, but also some new platforms that are worth
mentioning:
- Rockchip RK3399 platforms for Chromebooks, including Samsung
Chromebook Plus (Kevin)
- Orange Pi PC2 (Allwinner H5)
- Freescale LS2088A and LS1088A SoCs
- Expanded support for Nvidia Tegra186 (and Jetson TX2)"

* 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
|
|
- 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
|
|
- 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>;
|
|
};
