21:07 <TJ[m]> I need to use I2S LPI in SM8550, the downstream kernel use lpi_i2s3 as SEP_MI2S_TDM_AUXPCM, it use CLOCK_ID_SEP_MI2S_IBIT 0x10D which is in Mainline the 0x10D are assigned to Q6PRM_LPASS_CLK_ID_SEN_MI2S_IBIT, so it's clock id are Septenary in downstream and Senary in Mainline, I was setup the gpio config needed in &lpass_tlmm and set the 1536000 to LPASS_CLK_ID_SEN_MI2S_IBIT clock.

21:07 <TJ[m]> The codec reporting received clock but internal ppl are not locked. so I assume the i2s3_bck was working, but i2s_ws and i2s_data are not functioning yet.

21:15 <TJ[m]> In mainline the I2S are up to Quinary, there is no Senary and Septenary, and in audioreach-topology also same, I only see the I2S_INTF_TYPE are from I2S_INTF_TYPE_PRIMARY(0) up to I2S_INTF_TYPE_QUINARY(4)

21:15 <TJ[m]> So anyone know which part to set the I2S interface to use septenary?

21:20 <TJ[m]> I'm testing to use I2S_INTF_TYPE_PRIMARY or I2S_INTF_TYPE_SECONDARY, there is no error from qcom-apm, but the codec are not can't lock pll, but when I try to use I2S_INTF_TYPE_TERTIARY and above, even try to manually use value...

21:31 <z3ntu> TJ: possible that nobody ever used the septenary i2s so nobody added support for it? I think many boards use quinary?

21:37 <TJ[m]> Yes it's up to quinary, but I mean for now I'm not sure are the lpi i2s was supported or not for sm8550 in mainline, if supported there is any step that I missed to use lpi i2s?

21:41 <TJ[m]> I also got qcom-apm error if using value other than I2S_INTF_TYPE_PRIMARY or I2S_INTF_TYPE_SECONDARY, so I'm not sure it's problem in kernel or in topology side.

21:56 <z3ntu> I've never used audioreach myself, or got much audio to work myself so I'm afraid I'm not much help here

21:57 <TJ[m]> Luca Weiss: No problem, thanks :D
