    1 Broadcom BCM2835 auxiliary peripheral support
    2 
    3 This binding uses the common clock binding:
    4     Documentation/devicetree/bindings/clock/clock-bindings.txt
    5 
    6 The auxiliary peripherals (UART, SPI1, and SPI2) have a small register
    7 area controlling clock gating to the peripherals, and providing an IRQ
    8 status register.
    9 
   10 Required properties:
   11 - compatible:   Should be "brcm,bcm2835-aux"
   12 - #clock-cells: Should be <1>. The permitted clock-specifier values can be
   13                   found in include/dt-bindings/clock/bcm2835-aux.h
   14 - reg:          Specifies base physical address and size of the registers
   15 - clocks:       The parent clock phandle
   16 
   17 Example:
   18 
   19         clocks: cprman@7e101000 {
   20                 compatible = "brcm,bcm2835-cprman";
   21                 #clock-cells = <1>;
   22                 reg = <0x7e101000 0x2000>;
   23                 clocks = <&clk_osc>;
   24         };
   25 
   26         aux: aux@7e215004 {
   27                 compatible = "brcm,bcm2835-aux";
   28                 #clock-cells = <1>;
   29                 reg = <0x7e215000 0x8>;
   30                 clocks = <&clocks BCM2835_CLOCK_VPU>;
   31         };
