   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

  19         clocks: cprman@7e101000 {
  20                 compatible = "brcm,bcm2835-cprman";
  21                 #clock-cells = <1>;
  22                 reg = <0x7e101000 0x2000>;
  23                 clocks = <&clk_osc>;
  24         };

  26         aux: aux@0x7e215004 {
  27                 compatible = "brcm,bcm2835-aux";
  28                 #clock-cells = <1>;
  29                 reg = <0x7e215000 0x8>;
  30                 clocks = <&clocks BCM2835_CLOCK_VPU>;
