[PATCH AUTOSEL 5.15 24/25] drm/amd/display: Remove interface for periodic interrupt 1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Aric Cyr <aric.cyr@xxxxxxx>

[ Upstream commit 97d8d6f075bd8f988589be02b91f6fa644d0b0b8 ]

[why]
Only a single VLINE interrupt is available so interface should not
expose the second one which is used by DMU firmware.

[how]
Remove references to periodic_interrupt1 and VLINE1 from DC interfaces.
