Bug Description
[Impact]
Platforms with AX201 BT fail to pass the power consumption tests
[Fix]
Intel provides us the patch to fix it.
https:/
Wa_14010685332 sequence toggles a SDE chicken bit on and then off as the final step when disabling interrupts in preparation for runtime suspend. And this sequence also fixes the issues that dispcnlunit1_
v2.
8b46cc6577f4 drm/i915: Tweaked Wa_14010685332 for all PCHs
[Test]
Verified on the Dell machines with AX201 BT on them.
[Where problems may occur]
This patch extend the s0ix fix from gen8 and gen11 to CNP, ICP, JSP, MCC, TGP, and ADP PCHs, and also move the Wa_14010685332 sequence from reset functions to suspend/resume functions. It won't affect old chips as there is a if statement to check the pch type, and new chips require this sequence to work well.
