dt-bindings: clock: Convert HiSilicon clocks to DT schema
Convert the HiSilicon Hi6220/Hi3660/Hi3670 clock bindings to DT schema format. Rearrange the binding documents splitting out the stub clock binding from everything else.

* Hisilicon Hi3660 Clock Controller
|
||||
|
||||
The Hi3660 clock controller generates and supplies clock to various
|
||||
controllers within the Hi3660 SoC.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: the compatible should be one of the following strings to
|
||||
indicate the clock controller functionality.
|
||||
|
||||
- "hisilicon,hi3660-crgctrl"
|
||||
- "hisilicon,hi3660-pctrl"
|
||||
- "hisilicon,hi3660-pmuctrl"
|
||||
- "hisilicon,hi3660-sctrl"
|
||||
- "hisilicon,hi3660-iomcu"
|
||||
- "hisilicon,hi3660-stub-clk"
|
||||
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
|
||||
- #clock-cells: should be 1.
|
||||
|
||||
Optional Properties:
|
||||
|
||||
- mboxes: Phandle to the mailbox for sending message to MCU.
|
||||
(See: ../mailbox/hisilicon,hi3660-mailbox.txt for more info)
|
||||
|
||||
Each clock is assigned an identifier and client nodes use this identifier
|
||||
to specify the clock which they consume.
|
||||
|
||||
All these identifier could be found in <dt-bindings/clock/hi3660-clock.h>.
|
||||
|
||||
Examples:
|
||||
crg_ctrl: clock-controller@fff35000 {
|
||||
compatible = "hisilicon,hi3660-crgctrl", "syscon";
|
||||
reg = <0x0 0xfff35000 0x0 0x1000>;
|
||||
#clock-cells = <1>;
|
||||
};
|
||||

||||
uart0: serial@fdf02000 {
|
||||
compatible = "arm,pl011", "arm,primecell";
|
||||
reg = <0x0 0xfdf02000 0x0 0x1000>;
|
||||
interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>;
|
||||
clocks = <&crg_ctrl HI3660_CLK_MUX_UART0>,
|
||||
<&crg_ctrl HI3660_PCLK>;

||||

* Hisilicon Hi6220 Clock Controller
|
||||
|
||||
Clock control registers reside in different Hi6220 system controllers,
|
||||
please refer the following document to know more about the binding rules
|
||||
for these system controllers:
|
||||
|
||||
Documentation/devicetree/bindings/arm/hisilicon/hisilicon.yaml
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: the compatible should be one of the following strings to
|
||||
indicate the clock controller functionality.
|
||||
|
||||
- "hisilicon,hi6220-acpu-sctrl"
|
||||
- "hisilicon,hi6220-aoctrl"
|
||||
- "hisilicon,hi6220-sysctrl"
|
||||
- "hisilicon,hi6220-mediactrl"
|
||||
- "hisilicon,hi6220-pmctrl"
|
||||
- "hisilicon,hi6220-stub-clk"
|
||||
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
|
||||
- #clock-cells: should be 1.
|
||||
|
||||
Optional Properties:
|
||||
|
||||
- hisilicon,hi6220-clk-sram: phandle to the syscon managing the SoC internal sram;
|
||||
the driver need use the sram to pass parameters for frequency change.
|
||||
|
||||
- mboxes: use the label reference for the mailbox as the first parameter, the
|
||||
second parameter is the channel number.
|
||||
|
||||
Example 1:
|
||||
sys_ctrl: sys_ctrl@f7030000 {
|
||||
compatible = "hisilicon,hi6220-sysctrl", "syscon";
|
||||
reg = <0x0 0xf7030000 0x0 0x2000>;
|
||||
#clock-cells = <1>;
|
||||
};
|
||||
|
||||
Example 2:
|
||||
stub_clock: stub_clock {
|
||||
compatible = "hisilicon,hi6220-stub-clk";
|
||||
hisilicon,hi6220-clk-sram = <&sram>;
|
||||
#clock-cells = <1>;
|
||||
mboxes = <&mailbox 1>;
|
||||
};
|
||||
|
||||
Each clock is assigned an identifier and client nodes use this identifier
|
||||
to specify the clock which they consume.
|
||||
|
||||
All these identifier could be found in <dt-bindings/clock/hi6220-clock.h>.
