1Broadcom BCM2835 auxiliary peripheral support 2 3This binding uses the common clock binding: 4 Documentation/devicetree/bindings/clock/clock-bindings.txt 5 6The auxiliary peripherals (UART, SPI1, and SPI2) have a small register 7area controlling clock gating to the peripherals, and providing an IRQ 8status register. 9 10Required 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 17Example: 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 }; 32
