i.MX8QM Rotate the display in SDK side

[vinothkumars]

Hi All,

I am using i.MX8QM with LVDS to HDMI display I needs to rotate the display in different degree like 0, 90, 180 in M4 Core. M4 Core using spl-imx8qm.bin file.

I would like to modify in M4 core in the following SDK for following application,

SDK: SDK_MEK-MIMX8QM

Application: RVC

Display : DPU

source: SPL

Is there any display hardware register to rotate the display ?

Thanks & Regards,
