Hello build bot (Jenkins), Shaunak Saha, Wonkyu Kim, Eric Herrmann, Ravishankar Sarawadi, Tim Wawrzynczak, Chiranjeevi Rapolu,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/44501
to look at the new patch set (#4).
Change subject: mb/google/volteer: Configure DP_HPD as PAD_NC and disable DdiPortHpd ......................................................................
mb/google/volteer: Configure DP_HPD as PAD_NC and disable DdiPortHpd
GPP_A19(DP_HPD1) and GPP_A20(DP_HPD2) were configured native function (NF1) without internal pull-down which wrongly presents HPD interrupts. DP_HPD had been removed for EVT design as those events are through eSPI. This change configures GPP_A19 and GPP_A20 to be no connection and disables DdiPort1Hpd and DdiPort2Hpd.
BUG=b:162566436 TEST=Booted to kernel and verified no kernel HPD pins assertion message on Voteer EVT board.
