clk registration by clk providers and debugfs "nice to haves" for rate
 constraints. I'll highlight that we're now setting the clk_init_data pointer
 inside struct clk_hw to NULL during clk_register(), which may break some
 drivers that thought they could use that pointer during normal operations. That
 change has been sitting in next for a while now but maybe something is still
 broken. We'l see. Other than that the core framework changes aren't invasive
 and they're fixing bugs, simplifying, and making things better.
 
 On the clk driver side we got the usual addition of new SoC support, new
 features for existing drivers, and bug fixes scattered throughout. The biggest
 diffstat is the Amlogic driver that gained CPU clk support in addition to
 migrating to the new way of specifying clk parents. After that the Qualcomm,
 i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
 clock controllers from those vendors.
 
 Core:
  - Drop NULL checks in clk debugfs
  - Add min/max rates to clk debugfs
  - Set clk_init_data pointer inside clk_hw to NULL after registration
  - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
  - Evict parents from parent cache when they're unregistered
 
 New Drivers:
  - Add clock driver for i.MX8MN SoCs
  - Support aspeed AST2600 SoCs
  - Support for Mediatek MT6779 SoCs
  - Support qcom SM8150 GCC and RPMh clks
  - Support qcom QCS404 WCSS clks
  - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
  - Addition of clock driver for Rockchip rk3308 SoCs
 
 Updates:
  - Add regulator support to the cdce925 clk driver
  - Add support for Raspberry Pi 4 bcm2711 SoCs
  - Add SDIO gate support to aspeed driver
  - Add missing of_node_put() calls in various clk drivers
  - Migrate Amlogic driver to new clock parent description method
  - Add DVFS support to Amlogic Meson g12
  - Add Amlogic Meson g12a reset support to the axg audio clock controller
  - Add sm1 support to the Amlogic Meson g12a clock controller

  - Add Hifi4 DSP related clocks for i.MX8QXP SoC
  - Fix Audio PLL setting and parent clock for USB
  - Misc i.MX8 clock driver improvements and corrections
  - Set floor ops for Qualcomm SD clks so that rounding works
  - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1

* Rockchip RK3308 Clock and Reset Unit
The RK3308 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
Required Properties:
- compatible: CRU should be "rockchip,rk3308-cru"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- #reset-cells: should be 1.
Optional Properties:
- rockchip,grf: phandle to the syscon managing the "general register files"
If missing, pll rates are not changeable, due to the missing pll lock status.
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. All available clocks are defined as
preprocessor macros in the dt-bindings/clock/rk3308-cru.h headers and can be
used in device tree sources. Similar macros exist for the reset sources in
these files.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xin24m" - crystal input - required,
- "xin32k" - rtc clock - optional,
- "mclk_i2s0_8ch_in", "mclk_i2s1_8ch_in", "mclk_i2s2_8ch_in",
"mclk_i2s3_8ch_in", "mclk_i2s0_2ch_in",
"mclk_i2s1_2ch_in" - external I2S or SPDIF clock - optional,
- "mac_clkin" - external MAC clock - optional
Example: Clock controller node:
cru: clock-controller@ff500000 {
compatible = "rockchip,rk3308-cru";
reg = <0x0 0xff500000 0x0 0x1000>;
rockchip,grf = <&grf>;
#clock-cells = <1>;
#reset-cells = <1>;
};
Example: UART controller node that consumes the clock generated by the clock
controller:
uart0: serial@ff0a0000 {
compatible = "rockchip,rk3308-uart", "snps,dw-apb-uart";
reg = <0x0 0xff0a0000 0x0 0x100>;

* @name: clock name to find and parse. If name is NULL, the index is used
* @out_args: Result of parsing the clock specifier
*
* Parses a device node's "clocks" and "clock-names" properties to find the
* phandle and cells for the index or name that is desired. The resulting clock
* specifier is placed into @out_args, or an errno is returned when there's a
* parsing error. The @index argument is ignored if @name is non-NULL.
*
* Example:
*
* phandle1: clock-controller@1 {
* #clock-cells = <2>;
* }
*
* phandle2: clock-controller@2 {
* #clock-cells = <1>;
* }
*
* clock-consumer@3 {
* clocks = <&phandle1 1 2 &phandle2 3>;
* clock-names = "name1", "name2";
* }
*
* To get a device_node for `clock-controller@2' node you may call this
* function a few different ways:
*
* of_parse_clkspec(clock-consumer@3, -1, "name2", &args);
* of_parse_clkspec(clock-consumer@3, 1, NULL, &args);
* of_parse_clkspec(clock-consumer@3, 1, "name2", &args);
*
* Return: 0 upon successfully parsing the clock specifier. Otherwise, -ENOENT
* if @name is NULL or -EINVAL if @name is non-NULL and it can't be found in
* the "clock-names" property of @np.
