* Amlogic GXBB AO Clock and Reset Unit
|
||||||
|
|
||||||
|
The Amlogic GXBB AO clock controller generates and supplies clock to various
|
||||||
|
controllers within the Always-On part of the SoC.
|
||||||
|
|
||||||
|
Required Properties:
|
||||||
|
|
||||||
|
- compatible: should be "amlogic,gxbb-aoclkc"
|
||||||
|
- reg: physical base address of the clock controller and length of memory
|
||||||
|
mapped region.
|
||||||
|
|
||||||
|
- #clock-cells: should be 1.
|
||||||
|
|
||||||
|
Each clock is assigned an identifier and client nodes can use this identifier
|
||||||
|
to specify the clock which they consume. All available clocks are defined as
|
||||||
|
preprocessor macros in the dt-bindings/clock/gxbb-aoclkc.h header and can be
|
||||||
|
used in device tree sources.
|
||||||
|
|
||||||
|
- #reset-cells: should be 1.
|
||||||
|
|
||||||
|
Each reset is assigned an identifier and client nodes can use this identifier
|
||||||
|
to specify the reset which they consume. All available resets are defined as
|
||||||
|
preprocessor macros in the dt-bindings/reset/gxbb-aoclkc.h header and can be
|
||||||
|
used in device tree sources.
|
||||||
|
|
||||||
|
Example: AO Clock controller node:
|
||||||
|
|
||||||
|
clkc_AO: clock-controller@040 {
|
||||||
|
compatible = "amlogic,gxbb-aoclkc";
|
||||||
|
reg = <0x0 0x040 0x0 0x4>;
|
||||||
|
#clock-cells = <1>;
|
||||||
|
#reset-cells = <1>;
|
||||||
|
};
|
||||||
|
|
||||||
|
Example: UART controller node that consumes the clock and reset generated
|
||||||
|
by the clock controller:
|
||||||
|
|
||||||
|
uart_AO: serial@4c0 {
|
||||||
|
compatible = "amlogic,meson-uart";
|
||||||
|
reg = <0x4c0 0x14>;
|
||||||
|
interrupts = <0 90 1>;
|
||||||
|
clocks = <&clkc_AO CLKID_AO_UART1>;
|
||||||
|
resets = <&clkc_AO RESET_AO_UART1>;
|
||||||
|
status = "disabled";

||||||
|

* Amlogic Secure Monitor
|
||||||
|
|
||||||
|
In the Amlogic SoCs the Secure Monitor code is used to provide access to the
|
||||||
|
NVMEM, enable JTAG, set USB boot, etc...
|
||||||
|
|
||||||
|
Required properties for the secure monitor node:
|
||||||
|
- compatible: Should be "amlogic,meson-gxbb-sm"
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
firmware {
|
||||||
|
sm: secure-monitor {
|
||||||
|
compatible = "amlogic,meson-gxbb-sm";
|
