How can I set the HTMI output from landscape(default) to portrait

[linux_downey]

As the title，I'm developing a QT5 application and it must be displayed on a   portrait screen, I tried the QT rotation-API,But the results didn't meet my requirements ,and I wanted to switch the hdmi output to vertical display.

environment as below:

1.  i.mx8mq evk

2.  image name : fsl-image-qt5-validation-imx-imx8mqevk-20190923102914.rootfs.sdcard

3.  display with wayland.  

thanks!

best regards.
