* 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:
|
||
|
|
