I have a imx7ulpevk along with TFT3P5581-T LCD. I flashed imx-image-full-imx7ulpevk from L4.19.35_1.1.0_images_MX7ULPEVK package on uSD card. With this image I see serial logs but nothing is coming on LCD display except backlight.
Here are logs related to display:
------------------------------------------------------------------------------------------------------------------
pwm-backlight backlight: backlight supply power not found, using dummy regulator
pwm-backlight backlight: Linked as a consumer to regulator.0
mipi_dsi_northwest 40a90000.mipi_dsi: i.MX MIPI DSI driver probed
adv7535 probing phase
adv7535 0-003d: main addr = 0x3d
i2c i2c-0: chip_rev = 0x14
adv7535 0-003d: dsi cec addr = 0x78
adv7535 0-003d: adv7535 probe finished

mxsfb 40aa0000.lcdif: registered mxc display driver mipi_dsi_northwest
Console: switching to colour frame buffer device 80x30
------------------------------------------------------------------------------------------------------------------
I even tried to change dtb file with following steps:
------------------------------------------------------------------------------------------------------------------
setenv fdt_file imx7ulp-evkb-mipi.dtb
saveenv
boot
------------------------------------------------------------------------------------------------------------------
Am I missing anything?

Hi Raxesh
some board revisions require reworking for enabling mipi, it is described on p.6 MIPI Display & Touch
