How to define SPI outputs as "HighDrive" (H0H1) outputs in a overlay file

Question

Hello,

I want to define SPI outputs as highdrive outputs in a overlay file.

I know how to do this in the code:

const nrf_gpio_pin_drive_t SpiPinDrive = NRF_GPIO_PIN_H0H1;
nrf_gpio_reconfigure(NRF_GPIO_PIN_MAP(1, 12), NULL, NULL, NULL, &SpiPinDrive, NULL);   // CS
nrf_gpio_reconfigure(NRF_GPIO_PIN_MAP(1, 13), NULL, NULL, NULL, &SpiPinDrive, NULL);   // CLK
nrf_gpio_reconfigure(NRF_GPIO_PIN_MAP(1, 14), NULL, NULL, NULL, &SpiPinDrive, NULL);   // MOSI

But I want to do this in this overlay file:

&pinctrl {
	spi4_default: spi4_default {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 1, 13)>,     // CLK:  P1.13 - Pin 6
					<NRF_PSEL(SPIM_MOSI, 1, 14)>,    // MOSI: P1.14 - Pin 5
					<NRF_PSEL(SPIM_MISO, 1, 15)>;    // MISO: P1.15 - Pin 2					
		};
	};

	spi4_sleep: spi4_sleep {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 1, 13)>,     // CLK:  P1.13 - Pin 6
					<NRF_PSEL(SPIM_MOSI, 1, 14)>,    // MOSI: P1.14 - Pin 5
					<NRF_PSEL(SPIM_MISO, 1, 15)>;    // MISO: P1.15 - Pin 2
			low-power-enable;
		};
	};
};

my_spi4: &spi4 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	pinctrl-0 = <&spi4_default>;
	pinctrl-1 = <&spi4_sleep>;
	cs-gpios = <&gpio1 12 GPIO_ACTIVE_LOW>;  // CS: P 1.12 - Pin 1
  m25p40: M25P40v@0 {
		compatible = "jedec,spi-nor";
		label = "M25P40";
		reg = < 0 >;
		spi-max-frequency = < 40000000 >;
		size = < 0x4000000 >;
		jedec-id = [ C2 20 13 ];
	};  
};

How do I have to modify the overlay file to achieve this ?

I am using SDK 2.0.0 & nRF5340-DK.

Thank you !

Best regards,

Georg
