-Broadcom Kona Family Clocks
-
-This binding is associated with Broadcom SoCs having "Kona" style
-clock control units (CCUs). A CCU is a clock provider that manages
-a set of clock signals. Each CCU is represented by a node in the
-device tree.
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible
- Shall have a value of the form "brcm,<model>-<which>-ccu",
- where <model> is a Broadcom SoC model number and <which> is
- the name of a defined CCU. For example:
- "brcm,bcm11351-root-ccu"
- The compatible strings used for each supported SoC family
- are defined below.
-- reg
- Shall define the base and range of the address space
- containing clock control registers
-- #clock-cells
- Shall have value <1>. The permitted clock-specifier values
- are defined below.
-- clock-output-names
- Shall be an ordered list of strings defining the names of
- the clocks provided by the CCU.
-
-Device tree example:
-
- slave_ccu: slave_ccu {
- compatible = "brcm,bcm11351-slave-ccu";
- reg = <0x3e011000 0x0f00>;
- #clock-cells = <1>;
- clock-output-names = "uartb",
- "uartb2",
- "uartb3",
- "uartb4";
- };
-
- ref_crystal_clk: ref_crystal {
- #clock-cells = <0>;
- compatible = "fixed-clock";
- clock-frequency = <26000000>;
- };
-
- uart@...02000 {
- compatible = "brcm,bcm11351-dw-apb-uart", "snps,dw-apb-uart";
- reg = <0x3e002000 0x1000>;
- clocks = <&slave_ccu BCM281XX_SLAVE_CCU_UARTB3>;
- interrupts = <GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>;
- reg-shift = <2>;
- reg-io-width = <4>;
- };

-BCM281XX family
----------------
-CCU compatible string values for SoCs in the BCM281XX family are:
- "brcm,bcm11351-root-ccu"
- "brcm,bcm11351-aon-ccu"
- "brcm,bcm11351-hub-ccu"
- "brcm,bcm11351-master-ccu"
- "brcm,bcm11351-slave-ccu"
-
-The following table defines the set of CCUs and clock specifiers for
-BCM281XX family clocks. When a clock consumer references a clocks,
-its symbolic specifier (rather than its numeric index value) should
-be used. These specifiers are defined in:
- "include/dt-bindings/clock/bcm281xx.h"
