Hello,

 

I want to used tinydrm spi lcd.

The dts file  has been modified 

 

&ecspi1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi1 &pinctrl_ecspi1_cs>;
status = "okay";
cs-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>;
num-cs = <1>;
spi-3wire;

display@0{
compatible ="multi-inno,mi0283qt";
reg = <0>;
spi-max-frequency = <50000000>;
/* dc-gpios = <&pio>; */
reset-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;/* MX8MM_IOMUXC_SAI5_RXFS_GPIO3_IO19 */
rotation = <0>;
};
};

 

mi0283qt spi0.0: Failed to set dma mask -5 ( dma_coerce_mask_and_coherent)

 

i don't know, it return an error.

Can not use tinydrm modules ?

what's the problem ?
