Hello everyone,

 

I am using imx6ulevk eavaluation kit. I am using yocto following L4.9.88_2.0.0 user guide.

My evaluation kit has lcd. I want to understand its initialization routine.

Could someone please help me with reg address in device tree

lcdif: lcdif@21c8000 {
compatible = "fsl,imx6ul-lcdif", "fsl,imx28-lcdif";
reg = <0x021c8000 0x4000>;
interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6UL_CLK_LCDIF_PIX>,
<&clks IMX6UL_CLK_LCDIF_APB>,
<&clks IMX6UL_CLK_DUMMY>;
clock-names = "pix", "axi", "disp_axi";

status = "disabled";

}

where is the reg address 0x021c8000  defined ? In reference manual or user guide.

How can I know interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH> is defined for lcd?

 

Regards,

Asma
