Bug description:
[Impact]
Any of the platforms we’ve been seeing SATA problems not going to deepest
state leads to other devices not getting there during long idle or s2idle. And
it also prevents the system from entering deeper PC state other than PC3.
[Fix]
Suggested from Intel and Dell to contains the following 4 commits,
and all of 4 commits are in v4.19-rc1
https://patchwork.kernel.org/patch/10502285/
https://patchwork.kernel.org/patch/10502287/
https://patchwork.kernel.org/patch/10535781/
https://patchwork.kernel.org/patch/10535783/
[Test]
Verified the power consumption on some new platforms, it improves the SATA
HDD power consumption around 0.5w during long idle.
[Regression Potential]
Low, the DEVSLP function is already validated when shipped with SLP_S0
support.
