I guess the led control MCU command is not limited to PCIe devices,
they should be able to be extended even on MT7921 USB and SDIO
devices, right ? if so, I think we can drop the MMIO limitation
condition to support more scenarios and to make it easier to
understand.

Hi Sean,
This software flow involves chip GPIO control and is related to the
module's circuit design. Only the PCIe module can provide support for
this, so can't drop.

Hi Quan,
Thanks for clearing that up quickly. I guess we can add it just for
MT7921E. I have another question: Will the new command you added work
with older firmware, or is it made only for the most recent firmware?
I'm worried it might not be compatible with the older MT7921 firmware.

Hi Sean,
We had completed compatible test for this modify,
no side-effect have been found for the combination
that with this modify and old version firmware,
However, in this combination, the LED function will not be effective
and requires a new version of firmware for the LED function to work.
