  1. Broadcom BCM2835 auxiliary peripheral support
  2. This binding uses the common clock binding:
  3. Documentation/devicetree/bindings/clock/clock-bindings.txt
  4. The auxiliary peripherals (UART, SPI1, and SPI2) have a small register
  5. area controlling clock gating to the peripherals, and providing an IRQ
  6. status register.
  7. Required properties:
  8. - compatible: Should be "brcm,bcm2835-aux"
  9. - #clock-cells: Should be <1>. The permitted clock-specifier values can be
  10. found in include/dt-bindings/clock/bcm2835-aux.h
  11. - reg: Specifies base physical address and size of the registers
  12. - clocks: The parent clock phandle
  13. Example:
  14. clocks: cprman@7e101000 {
  15. compatible = "brcm,bcm2835-cprman";
  16. #clock-cells = <1>;
  17. reg = <0x7e101000 0x2000>;
  18. clocks = <&clk_osc>;
  19. };
  20. aux: aux@0x7e215004 {
  21. compatible = "brcm,bcm2835-aux";
  22. #clock-cells = <1>;
  23. reg = <0x7e215000 0x8>;
  24. clocks = <&clocks BCM2835_CLOCK_VPU>;
  25. };
