I was able to extend, thanks everyone for the support. I attached my final dts, I also changed from spi4 to spi1, because I double check the pinount and spi4 is not mapped. In the original pinout armbian spi1 = orange pi 5 pro spi4. rk3588s-spi1-5cs-spidev.dts

I am trying to extend the chipselect from spi4. Because I will need to control more boards, so I tried to transform GPIO into chipselect (CS). This is the original SPI4: /dts-v1/; / { fragment@0 { target = <0xffffffff>; __overlay__ { status = "okay"; #address-cells = <0x01>; #size-cells = <0x00>; pinctrl-names = "default"; pinctrl-0 = <0xffffffff 0xffffffff 0xffffffff>; spidev@0 { compatible = "rockchip,spidev"; status = "okay"; reg = <0x00>; spi-max-frequency = <0x2faf080>; }; spidev@1 { compatible = "rockchip,spidev"; status = "okay"; reg = <0x01>; spi-max-frequency = <0x2faf080>; }; }; }; __fixups__ { spi4 = "/fragment@0:target:0"; spi4m1_cs0 = "/fragment@0/__overlay__:pinctrl-0:0"; spi4m1_cs1 = "/fragment@0/__overlay__:pinctrl-0:4"; spi4m1_pins = "/fragment@0/__overlay__:pinctrl-0:8"; }; }; And this is the my change that is compiling with warning: /dts-v1/; / { fragment@0 { target = <0xffffffff>; __overlay__ { status = "okay"; #address-cells = <1>; #size-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <0xffffffff 0xffffffff 0xffffffff>; cs-gpios = < 0xffffffff 4 1 /* CS2: GPIO1_A4 */ 0xffffffff 6 1 /* CS3: GPIO1_A6 */ 0xffffffff 7 1 /* CS4: GPIO4_A7 */ >; spidev@0 { compatible = "rockchip,spidev"; reg = <0>; spi-max-frequency = <50000000>; status = "okay"; }; spidev@1 { compatible = "rockchip,spidev"; reg = <1>; spi-max-frequency = <50000000>; status = "okay"; }; spidev@2 { compatible = "rockchip,spidev"; reg = <2>; spi-max-frequency = <50000000>; status = "okay"; }; spidev@3 { compatible = "rockchip,spidev"; reg = <3>; spi-max-frequency = <50000000>; status = "okay"; }; spidev@4 { compatible = "rockchip,spidev"; reg = <4>; spi-max-frequency = <50000000>; status = "okay"; }; }; }; __fixups__ { spi4 = "/fragment@0:target:0"; spi4m1_cs0 = "/fragment@0/__overlay__:pinctrl-0:0"; /* CS0 */ spi4m1_cs1 = "/fragment@0/__overlay__:pinctrl-0:4"; /* CS1 */ spi4m1_pins = "/fragment@0/__overlay__:pinctrl-0:8"; /* SCLK/MISO/MOSI */ spi4m1_cs2 = "/fragment@0/__overlay__:cs-gpios:0"; /* CS2 */ spi4m1_cs3 = "/fragment@0/__overlay__:cs-gpios:1"; /* CS3 */ spi4m1_cs4 = "/fragment@0/__overlay__:cs-gpios:2"; /* CS4 */ }; };
