[PATCH] dt-bindings: clock: Convert HiSilicon clocks to DT schema
From: Rob Herring (Arm)
Date: Thu Oct 01 2026 - 17:28:05 EST
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>;
- clock-names = "uartclk", "apb_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>;

-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>.
