Please do it as follows (ie move under soc node).

	soc {
		compatible = "st,stm32h5ef", "st,stm32h5", "simple-bus";

		pinctrl: pin-controller@xxxxxxxxxx {
			gpioh: gpio@42021c00 {
				compatible = "st,stm32-gpio";
				gpio-controller;
				#gpio-cells = <2>;
				reg = <0x42021c00 0x400>;
				clocks = <&rcc STM32_CLOCK(AHB2, 7)>;
			};

			gpioj: gpio@42022400 {
				compatible = "st,stm32-gpio";
				gpio-controller;
				#gpio-cells = <2>;
				reg = <0x42022400 0x400>;
				clocks = <&rcc STM32_CLOCK(AHB2, 9)>;
			};

			gpiok: gpio@42022800 {
				compatible = "st,stm32-gpio";
				gpio-controller;
				#gpio-cells = <2>;
				reg = <0x42022800 0x400>;
				clocks = <&rcc STM32_CLOCK(AHB2, 26)>;
			};
		};

This is the same in the end, but preferred for consistency
