drm/amd/display: log destination of vertical interrupt
[Why] Knowing the destination of OTG's vertical interrupt 2 is useful for debugging, but it is not currently included in the OTG state readback logic [How] Read the OTG interrupt destination register to get the vertical interrupt 2 destination on ASICs that have this register when reading back the OTG state from hardware Reviewed-by: Sung Lee <[email protected]> Reviewed-by: Aric Cyr <[email protected]> Signed-off-by: Josip Pavic <[email protected]> Signed-off-by: Wayne Lin <[email protected]> Tested-by: Daniel Wheeler <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
