dt-bindings: clock: brcm,kona-ccu: convert to YAML
Convert Broadcom Kona family clock controller unit (CCU) bindings
to DT schema.
Changes during conversion:
- remove "dmac" from clock-output-names for brcm,bcm11351-master-ccu,
such a clock doesn't exist
- remove "uartb4" from clock-output-names for brcm,bcm21664-slave-ccu,
such a clock doesn't exist

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";
|
||||

|
||||
};
|
||||
|
||||
uart@3e002000 {
|
||||
compatible = "brcm,bcm11351-dw-apb-uart", "snps,dw-apb-uart";
|
||||
reg = <0x3e002000 0x1000>;
|
||||

|
||||
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"
|
||||

||||
