Kernel-4.18.0-80.el8_brcm,bcm2835-aux-clock

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@7e215004 {
    compatible = "brcm,bcm2835-aux";
    #clock-cells = <1>;
    reg = <0x7e215000 0x8>;
    clocks = <&clocks BCM2835_CLOCK_VPU>;
};
