Subject: dt-bindings: clock: milbeaut: Drop providers and consumers from
example
Convention for examples is to only show what's covered by the binding,
so drop the consumer "socionext,milbeaut-usio-uart" and input clock
provider "fixed-clock" from the example. "socionext,milbeaut-usio-uart"
is also not documented by a schema which caused a warning.

Subject: dt-bindings: clock: qoriq-clock: convert to yaml format
Convert qoria-clock DT binding to yaml format. Split to two files
qoriq-clock.yaml and qoriq-clock-legancy.yaml.
Addtional change:
- Remove clock consumer part in example
- Fixed example dts error
- Deprecated legancy node
- fsl,b4420-clockgen and fsl,b4860-clockgen fallback to fsl,b4-clockgen.

-* Clock Block on Freescale QorIQ Platforms
-
-Freescale QorIQ chips take primary clocking input from the external
-SYSCLK signal. The SYSCLK input (frequency) is multiplied using
-multiple phase locked loops (PLL) to create a variety of frequencies
-which can then be passed to a variety of internal logic, including
-cores and peripheral IP blocks.
-Please refer to the Reference Manual for details.
-
-All references to "1.0" and "2.0" refer to the QorIQ chassis version to
-which the chip complies.
-
-Chassis Version Example Chips
---------------- -------------
-1.0 p4080, p5020, p5040
-2.0 t4240, b4860
-
-1. Clock Block Binding
-
-Required properties:
-- compatible: Should contain a chip-specific clock block compatible
- string and (if applicable) may contain a chassis-version clock
- compatible string.
-
- Chip-specific strings are of the form "fsl,<chip>-clockgen", such as:
- * "fsl,p2041-clockgen"
- * "fsl,p3041-clockgen"
- * "fsl,p4080-clockgen"
- * "fsl,p5020-clockgen"
- * "fsl,p5040-clockgen"
- * "fsl,t1023-clockgen"
- * "fsl,t1024-clockgen"
- * "fsl,t1040-clockgen"
- * "fsl,t1042-clockgen"
- * "fsl,t2080-clockgen"
- * "fsl,t2081-clockgen"
- * "fsl,t4240-clockgen"
- * "fsl,b4420-clockgen"
- * "fsl,b4860-clockgen"
- * "fsl,ls1012a-clockgen"
- * "fsl,ls1021a-clockgen"
- * "fsl,ls1028a-clockgen"
- * "fsl,ls1043a-clockgen"
- * "fsl,ls1046a-clockgen"
- * "fsl,ls1088a-clockgen"
- * "fsl,ls2080a-clockgen"
- * "fsl,lx2160a-clockgen"
- Chassis-version clock strings include:
- * "fsl,qoriq-clockgen-1.0": for chassis 1.0 clocks
- * "fsl,qoriq-clockgen-2.0": for chassis 2.0 clocks
-- reg: Describes the address of the device's resources within the
- address space defined by its parent bus, and resource zero
- represents the clock register set
-
-Optional properties:
-- ranges: Allows valid translation between child's address space and
- parent's. Must be present if the device has sub-nodes.
-- #address-cells: Specifies the number of cells used to represent
- physical base addresses. Must be present if the device has
- sub-nodes and set to 1 if present
-- #size-cells: Specifies the number of cells used to represent
- the size of an address. Must be present if the device has
- sub-nodes and set to 1 if present
-- clock-frequency: Input system clock frequency (SYSCLK)
-- clocks: If clock-frequency is not specified, sysclk may be provided
- as an input clock. Either clock-frequency or clocks must be
- provided.
- A second input clock, called "coreclk", may be provided if
- core PLLs are based on a different input clock from the
- platform PLL.
-- clock-names: Required if a coreclk is present. Valid names are
- "sysclk" and "coreclk".
-
-2. Clock Provider
-
-The clockgen node should act as a clock provider, though in older device
-trees the children of the clockgen node are the clock providers.
-
-When the clockgen node is a clock provider, #clock-cells = <2>.
-The first cell of the clock specifier is the clock type, and the
-second cell is the clock index for the specified type.
-
- Type# Name Index Cell
- 0 sysclk must be 0
- 1 cmux index (n in CLKCnCSR)
- 2 hwaccel index (n in CLKCGnHWACSR)
- 3 fman 0 for fm1, 1 for fm2
- 4 platform pll n=pll/(n+1). For example, when n=1,
- that means output_freq=PLL_freq/2.
- 5 coreclk must be 0
-
-3. Example
-
- clockgen: global-utilities@e1000 {
- compatible = "fsl,p5020-clockgen", "fsl,qoriq-clockgen-1.0";
- clock-frequency = <133333333>;
- reg = <0xe1000 0x1000>;
- #clock-cells = <2>;
- };
-
- fman@400000 {
- ...
- clocks = <&clockgen 3 0>;
- ...
- };
-}
-4. Legacy Child Nodes
-
-NOTE: These nodes are deprecated. Kernels should continue to support
-device trees with these nodes, but new device trees should not use them.
-
-Most of the bindings are from the common clock binding[1].
- [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : Should include one of the following:
- * "fsl,qoriq-core-pll-1.0" for core PLL clocks (v1.0)
- * "fsl,qoriq-core-pll-2.0" for core PLL clocks (v2.0)
- * "fsl,qoriq-core-mux-1.0" for core mux clocks (v1.0)
- * "fsl,qoriq-core-mux-2.0" for core mux clocks (v2.0)
- * "fsl,qoriq-sysclk-1.0": for input system clock (v1.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-sysclk-2.0": for input system clock (v2.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-platform-pll-1.0" for the platform PLL clock (v1.0)
- * "fsl,qoriq-platform-pll-2.0" for the platform PLL clock (v2.0)
-- #clock-cells: From common clock binding. The number of cells in a
- clock-specifier. Should be <0> for "fsl,qoriq-sysclk-[1,2].0"
- clocks, or <1> for "fsl,qoriq-core-pll-[1,2].0" clocks.
- For "fsl,qoriq-core-pll-[1,2].0" clocks, the single
- clock-specifier cell may take the following values:
- * 0 - equal to the PLL frequency
- * 1 - equal to the PLL frequency divided by 2
- * 2 - equal to the PLL frequency divided by 4
-
-Recommended properties:
-- clocks: Should be the phandle of input parent clock
-- clock-names: From common clock binding, indicates the clock name
-- clock-output-names: From common clock binding, indicates the names of
- output clocks
-- reg: Should be the offset and length of clock block base address.
- The length should be 4.

-Spreadtrum SC9860 Clock Binding
-------------------------
-
-Required properties:
-- compatible: should contain the following compatible strings:
- - "sprd,sc9860-pmu-gate"
- - "sprd,sc9860-pll"
- - "sprd,sc9860-ap-clk"
- - "sprd,sc9860-aon-prediv"
- - "sprd,sc9860-apahb-gate"
- - "sprd,sc9860-aon-gate"
- - "sprd,sc9860-aonsecure-clk"
- - "sprd,sc9860-agcp-gate"
- - "sprd,sc9860-gpu-clk"
- - "sprd,sc9860-vsp-clk"
- - "sprd,sc9860-vsp-gate"
- - "sprd,sc9860-cam-clk"
- - "sprd,sc9860-cam-gate"
- - "sprd,sc9860-disp-clk"
- - "sprd,sc9860-disp-gate"
- - "sprd,sc9860-apapb-gate"
-
-- #clock-cells: must be 1
-
-- clocks : Should be the input parent clock(s) phandle for the clock, this
- property here just simply shows which clock group the clocks'
- parents are in, since each clk node would represent many clocks
- which are defined in the driver. The detailed dependency
- relationship (i.e. how many parents and which are the parents)
- are implemented in driver code.
-
-Optional properties:
-
-- reg: Contain the registers base address and length. It must be configured
- only if no 'sprd,syscon' under the node.
-
-- sprd,syscon: phandle to the syscon which is in the same address area with
- the clock, and so we can get regmap for the clocks from the
- syscon device.
-
-Example:
-
- pmu_gate: pmu-gate {
- compatible = "sprd,sc9860-pmu-gate";
- sprd,syscon = <&pmu_regs>;
- clocks = <&ext_26m>;
- #clock-cells = <1>;
- };
-
- pll: pll {
- compatible = "sprd,sc9860-pll";
- sprd,syscon = <&ana_regs>;
- clocks = <&pmu_gate 0>;
- #clock-cells = <1>;
- };
-
- ap_clk: clock-controller@20000000 {
- compatible = "sprd,sc9860-ap-clk";
- reg = <0 0x20000000 0 0x400>;
- clocks = <&ext_26m>, <&pll 0>,
- <&pmu_gate 0>;
- #clock-cells = <1>;
- };

Add required syscon compatible for mt7622 pciesys. This is required for
SATA interface as the regs are shared.

The MT8188 sys clocks embed a reset controller: add #reset-cells
to the binding to allow using resets.

Subject: dt-bindings: clock: airoha: Add reset support to EN7581 clock binding
Introduce reset capability to EN7581 device-tree clock binding
documentation. Add reset register mapping between misc scu and pb scu
ones in order to follow the memory order. This change is not
introducing any backward compatibility issue since the EN7581 dts is not
upstream yet.
