There is a downstream patch to gate off APll_PFD1/2/3, with that patch applied you will not see kernel warning.

i.MX7ULP: change USDHC clock rate

Change USDHC0 and USDHC1 per clock source from APLL_PFD1,
and set the APll_PFD1 clock rate to 352.8MHz.

Also gate off APll_PFD1/2/3 before boot OS, otherwise set
the clock rate of APll_PFD1/2/3 during OS boot up will triger
some warning message.

Thanks for the clarification. We can upstream this one later then.

Any insight about the "ERROR: reserving fdt memory region failed" messages?

It is because the rpmsg reserved region in Linux dts conflicts with uboot region. It not impact Linux boot.

Regards, Peng.

Thanks
