i have encountered the same problem as yours. i have downloaded the latest armbian from release page(my board is OrangePi Zero),flash it into sd card,and wrote this overlay:
/dts-v1/;
/plugin/;
/ {
compatible = "allwinner,sun8i-h3";
fragment@0 {
target-path = "/aliases";
__overlay__ {
spi0 = "/soc/spi@1c68000";
};
};
fragment@1 {
target = <&spi0>;
__overlay__ {
#address-cells = <0>;
#size-cells = <0>;
status = "okay";
spidev {
compatible = "spidev";
status = "okay";
reg = <0>;
spi-max-frequency = <1000000>;
};
};
};
};
after applying it using `sudo armbian-add-overlay spi0.dts`,it *seems* to be loaded correctly(i use a usb-serial wire to observe console log from on-board debugging serial,it shows "Applying user provided DT overlay spi1.dtbo" and no errors occurred),but when i logged in system,there were no /dev/spidev* show up.
also, i have noticed there are some spi error in kernel log:
[ 1.928114] sun6i-spi 1c68000.spi: chipselect 0 already in use
[ 1.928149] spi_master spi0: spi_device register error /soc/spi@1c68000/flash@0
[ 1.928200] spi_master spi0: Failed to create SPI device for /soc/spi@1c68000/flash@0
when i change the spi0 to spi1 , the whole spi thing will not work,even if i have checked the `/proc/device-tree/soc/spi@1c690000/spidev/status` file is "okay"(and dmesg shows nothing related to spi). doesn't know what kinda thing happened.
sorry for my pool English,i'm not a native English speaker.
i wish these infomations will help the developer.
arclight got a reaction from going in 5.15.25 breaks SPI on NanoPi Neo and does not create /dev/spidev0.0
