Sure, will update.

Hi Krzysztof,
IPQ5018 only supports running at 1.1GHz, but its running at 800MHz
by default from the bootloader so there is only one OPP.
Isn't this contradictory? If it is running at 800 initially, then it
supports running at 800...
I can only guess that it's not validated at 800MHz.
As per the h/w design team, there is negligible power or thermal benefit
by lowering to 800MHz clock.
Hence, 800MHz opp wasn't included here.
Just my 2c. If 800 MHz is supported, it should be included. Even if
just to prevent the kernel from throwing a warning about the CPU
running at the unsupported frequency. Then one can use scheduler
tunings to prevent the CPU from going to 800 MHz state.
sure, understood. Will add opp at 800MHz. Thanks.
Regards,
Gokul
