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?

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?

regards,
