* 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 {

* Amlogic Meson IR remote control receiver
|
||||
|

Required properties:
|
||||
- compatible : should be "amlogic,meson6-ir"
|
||||
- compatible : depending on the platform this should be one of:

- "amlogic,meson6-ir"
|

- "amlogic,meson8b-ir"

- "amlogic,meson-gxbb-ir"

- reg : physical base address and length of the device registers

- interrupts : a single specifier for the interrupt from the device
