(Nit: Kaanapali is SM8850.)
Tested on a Lenovo Legion Tab Y700 Gen 5 (SM8850), v7.3-rc4, bonded DSI
panel with DSC plus DP over USB-C:
- without the series the INT2 GDSC stays off with no consumer; with it
the DPU holds it on while the display is on
- DPMS off turns INT2 and CORE off, DPMS on brings them back; s2idle
works
- with a DP monitor attached the cursor plane lands on DMA5 (sspp_13)
and scans out fine; VIG2/VIG3 were not exercised
