Bug description:
[Impact]
Platforms with AX201 BT fail to pass the power consumption tests
[Fix]
Intel provides us the patch to fix it.
https://patchwork.kernel.org/project/intel-gfx/patch/20210325120947.11950-1-anshuman.gu...@intel.com/
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_cp_xosc_clkreq clock keeps to be active on TGL-H during
s2idle.
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.
