Hi,
We are getting below messages for SPI0 cs
[ 16.177670] spi_master spi1: GPIO lookup for consumer cs

Our Device tree ia as below

pinctrl-names = "default";
pinctrl-0 = <&main_spi0_pins_default>;
ti,pindir-d0-out-d1-in = <1>;

cs-gpios = <&gpio1 42 GPIO_ACTIVE_LOW> //<0>;

//compatible = "spidev";
//compatible = "linux,spidev";
compatible = "rohm,dh2228fv";

};
};

};
we want write only option on spi
please tell us why this messages are coming.
