fb_st7789v.c in kernel 5.10 the color was swapped

Hi there,

I'm working with LCD via st7789v. I've already connected to my board. The device tree show below:

`spi0: spi@400 { compatible = "microchip,sam9x60-spi", "atmel,at91rm9200-spi"; reg = <0x400 0x200>; interrupts = <13 IRQ_TYPE_LEVEL_HIGH 7>; clocks = <&pmc PMC_TYPE_PERIPHERAL 13>; clock-names = "spi_clk"; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_flx4_default>; atmel,fifo-size = <16>;

address-cells = <1>;

            #size-cells = <0>;

            status = "okay";

            lcd@0 {
                compatible = "sitronix,st7789v";
                buswidth = <8>;
                reg = <0>;
                pinctrl-name = "default";
                spi-max-frequency = <40000000>;
                spi-cpol;
                spi-cpha;
                rotate = <0>;
                rgb;
                fps = <50>;
                reset-gpios= <&pioA 2 0>;
                dc-gpios = <&pioA 3 0>;
                debug = <5>;
                status = "okay";

            };
    };

`

But when I try to run simple app by QT5 on board to display a picture, the color was swapped (white->black, yellow->blue...). I searched some topics about this problem but I can't find solution. Can anyone help me?

Any suggestion would be appreciate!

I've already fixed by setting

tft.invertDisplay(0);
