lcd initialisation and adress for imx6ul

[asmaa]

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

Hi Asma

one can look at uboot/board/freescale/mx6ul_14x14_evk/mx6ul_14x14_evk.c

mx6ul_14x14_evk.c\mx6ul_14x14_evk\freescale\board - uboot-imx - i.MX U-Boot 

in linux sect.6.3.4 ELCDIF Frame Buffer attached Linux Manual.

Right, reg address 0x021c8000 and interrupts are defined in Reference Manual.

Best regards

Hi igorpadykov‌,
