The reset driver now supports the ao reset controller, so update the documentation to match.

Hisilicon System Reset Controller
|
|
======================================
|
|
|
|
Please also refer to reset.txt in this directory for common reset
|
|
controller binding usage.
|
|
|
|
The reset controller registers are part of the system-ctl block on
|
|
hi6220 SoC.
|
|
|
|
Required properties:
|
|
- compatible: should be one of the following:
|
|
- "hisilicon,hi6220-sysctrl", "syscon" : For peripheral reset controller.
|
|
- "hisilicon,hi6220-mediactrl", "syscon" : For media reset controller.
|
|
- "hisilicon,hi6220-aoctrl", "syscon" : For ao reset controller.
|
|
- reg: should be register base and length as documented in the
|
|
datasheet
|
|
- #reset-cells: 1, see below
|
|
|
|
Example:
|
|
sys_ctrl: sys_ctrl@f7030000 {
|
|
compatible = "hisilicon,hi6220-sysctrl", "syscon";
|
|
reg = <0x0 0xf7030000 0x0 0x2000>;
|
|
#clock-cells = <1>;
|
|
#reset-cells = <1>;
|
|
};
|
|
|
|
Specifying reset lines connected to IP modules
|
|
==============================================
|
|
example:
|
|
|
|
uart1: serial@..... {
|
|
...
|
|
resets = <&sys_ctrl PERIPH_RSTEN3_UART1>;
|
|
...
|
|
};
|
|
