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 Tested-by: Joonhoe Kim <26rote@gmail.com>
