Hi,
In si_program_display_gap we have DISP1_GAP and DISP2_GAP.
Where are DISP3_GAP to DISP6_GAP? What does expect this hardware
block when more than 2 displays are connected? Is DISP2_GAP
actually stand for DISP[3-6]_GAP?
Still in the same function, what happened to the pipes for
DCCG_DISP[2-6]_SLOW_SELECT?
regards,

P.S. It seems that all this was "fixed" in CI with new hardware
blocks, but I'm focussing on SI blocks.

I noticed something else: in si_enable_display_gap, the
DISP1_GAP_MCHG and DISP2_GAP_MCHG fields from CG_DISPLAY_GAP_CNTL
get inited with DISP1 only to vblank, and never reprogrammed
with new displays like DISP[12]_GAP. It seems not consistant,
expected?
