Release: Yocto-Sumo (4.14.78_1.0.0_GA)
Board: i.MX8MQ based custom board
We are getting radiation from our board at 297 & 594 MHz frequencies, which is used by HDMI interface.
We want to disable DISPLAY_HDMI_CLK_ROOT on our board to stop the radiation of above frequencies. We already disabled HDMI interface from dts file.
Although, we are getting above clock frequencies and it is radiating due to PLL in the processor.
How we can completely disable the DISPLAY_HDMI_CLK_ROOT from PLL?
