I got following error:

$ make CHECK_DTBS=y rockchip/rk3588-rock-5-itx.dtb
   UPD     include/config/kernel.release
   DTC [C] arch/arm64/boot/dts/rockchip/rk3588-rock-5-itx.dtb
/home/radxa/linux/arch/arm64/boot/dts/rockchip/rk3588-rock-5-itx.dtb: 
mmc: sdmmc-det-gpio: {'rockchip,pins': [[0, 4, 0, 270]], 'phandle': 145} 
is not of type 'array'
	from schema $id: http://devicetree.org/schemas/gpio/gpio-consumer.yaml#

What's wrong?

Best regards,
