--- Comment #4 from Max Lee (max.lee@canonical.com) ---
On this platforms, OEM didn't design RTD3 on Maple Ridge.
Since the MR AIC is to share with other desktop projects, and the NVM was set
to Native + RTD3 enabled.
This cause the driver to get the RTD3 enabled from NVM. and set Linux TBT
controller in D3 state then PME doesn't toggled by device hot plug.
Current BIOS sent _S0W to TBT RP and the NVM native +RTD3 doesn't change to
native only. Is this a correct setting on the NVM to support non-RTD3 platform?
should BIOS sent command to modify NVM offset to disable RTD3?
