15:03 <marc|gonzalez> konradybcio: lumag: do you guys know of a board with functional audio over HDMI that I could copy from for msm8998?

15:04 <marc|gonzalez> At this point, 'tinymix contents' reports 1 control: BOOL 1 Headset Jack Off

15:11 <marc|gonzalez> hmmm, looking at sound/soc/qcom/lpass-hdmi.c & commit 7cb37b7bd0d3c9

15:13 <marc|gonzalez> Angelo's sound/soc/qcom/lpass-msm8998.c does include .ops = &asoc_qcom_lpass_hdmi_dai_ops for .id = LPASS_DP_RX in msm8998_lpass_cpu_dai_driver

15:15 <marc|gonzalez> lpass-sc7180.c & lpass-sc7280.c are the only drivers to have .ops = &asoc_qcom_lpass_hdmi_dai_ops

15:16 <marc|gonzalez> Looks like I'm probably missing a full DT node like lpass_cpu: audio@3987000

15:19 <marc|gonzalez> Found commit aee6873edb93a3 ... Are Srinivasa or Venkata active in the channel?

15:22 <konradybcio> marc|gonzalez: fwiw i don't think Angelo had any 98 board with hdmi

15:24 <marc|gonzalez> I know, I know (and I cry every night)

15:24 <marc|gonzalez> I'm just trying to bridge the missing parts with something that works from another board

15:25 <marc|gonzalez> I will confess that the sound subsystem is a huge black box for me at this point :(

15:26 <konradybcio> more of common knowledge than a confession

15:27 <marc|gonzalez> this is a snipe, right?

15:28 <marc|gonzalez> snipe or swipe

15:28 <konradybcio> What I meant to say is only a small bunch of people, not including myself, know stuff about sound/, and it doesnt seem to be terribly well documented

15:29 <marc|gonzalez> oh, because it could be read in a very different way smirk

15:30 <marc|gonzalez> the multimedia subsystems seem less well documented than others

15:31 <marc|gonzalez> konradybcio: sc7280 is like sdm845?

15:32 <konradybcio> Largely

15:32 <marc|gonzalez> but sdm845 no longer supports HDMI while sc7280 does?

15:33 <marc|gonzalez> lumag said something like msm8998 is the last chip with HDMI TX

15:38 <konradybcio> rg HDMI drivers/gpu/drm/msm/disp/dpu1/catalog gives you the answer

15:38 <konradybcio> (neither 845 nor 7280 has hdmi)

15:38 <konradybcio> some boards however ship with a dsi-hdmi bridge

15:39 <konradybcio> but then to mdss, it's still a DSI device
