Thank you for working on this! First of all this patch is:
Reviewed-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

Do you want me to send a patch to document the
"amlogic,meson-hhi-sysctrl" compatible string next?
We either have to update
Documentation/devicetree/bindings/soc/amlogic/amlogic,meson-gx-hhi-sysctrl.yaml
or create a similar binding file for the older SoCs.
Also I think when documenting that compatible string we'll have to add
per-SoC compatibles as I think this generic one is not enough.

Best regards,
Martin

I have it ready already, waiting for this one to go upstream first!

-* Amlogic Meson8, Meson8b and Meson8m2 Clock and Reset Unit
-
-The Amlogic Meson8 / Meson8b / Meson8m2 clock controller generates and
-supplies clock to various controllers within the SoC.
-
-Required Properties:
-
-- compatible: must be one of:
-	- "amlogic,meson8-clkc" for Meson8 (S802) SoCs
-	- "amlogic,meson8b-clkc" for Meson8 (S805) SoCs
-	- "amlogic,meson8m2-clkc" for Meson8m2 (S812) SoCs
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-- clocks: list of clock phandles, one for each entry in clock-names
-- clock-names: should contain the following:
-  * "xtal": the 24MHz system oscillator
-  * "ddr_pll": the DDR PLL clock
-  * "clk_32k": (if present) the 32kHz clock signal from GPIOAO_6 (CLK_32K_IN)
-
-Parent node should have the following properties :
-- compatible: "amlogic,meson-hhi-sysctrl", "simple-mfd", "syscon"
-- reg: base address and size of the HHI system control register space.
-
-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/meson8b-clkc.h header and can be
-used in device tree sources.
-
-Similarly a preprocessor macro for each reset line is defined in
-dt-bindings/reset/amlogic,meson8b-clkc-reset.h (which can be used from the
-device tree sources).
-
-
-Example: Clock controller node:
-
-	clkc: clock-controller {
-		compatible = "amlogic,meson8b-clkc";
-		#clock-cells = <1>;
-		#reset-cells = <1>;
-	};
-
-
-Example: UART controller node that consumes the clock generated by the clock
-  controller:
-
-	uart_AO: serial@c81004c0 {
-		compatible = "amlogic,meson-uart";
-		reg = <0xc81004c0 0x14>;
-		interrupts = <0 90 1>;
-		clocks = <&clkc CLKID_CLK81>;
-	};
