Broadcom BCM2835 auxiliary peripheral support
|
|
|
|
This binding uses the common clock binding:
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
The auxiliary peripherals (UART, SPI1, and SPI2) have a small register
|
|
area controlling clock gating to the peripherals, and providing an IRQ
|
|
status register.
|
|
|
|
Required properties:
|
|
- compatible: Should be "brcm,bcm2835-aux"
|
|
- #clock-cells: Should be <1>. The permitted clock-specifier values can be
|
|
found in include/dt-bindings/clock/bcm2835-aux.h
|
|
- reg: Specifies base physical address and size of the registers
|
|
- clocks: The parent clock phandle
|
|
|
|
Example:
|
|
|
|
clocks: cprman@7e101000 {
|
|
compatible = "brcm,bcm2835-cprman";
|
|
#clock-cells = <1>;
|
|
reg = <0x7e101000 0x2000>;
|
|
clocks = <&clk_osc>;
|
|
};
|
|
|
|
aux: aux@0x7e215004 {
|
|
compatible = "brcm,bcm2835-aux";
|
|
#clock-cells = <1>;
|
|
reg = <0x7e215000 0x8>;
|
|
clocks = <&clocks BCM2835_CLOCK_VPU>;
|
|
};
