I think I solved my head-phones one-channel problem.
This should be <1 2 3> and in DTSI:
qcom,din-ports = <3>;
WCD938x TX device has 4 SoundWire ports and LPASS TX macro SoundWire
Master has 3 ports this mapping qcom,tx-port-mapping = <1 1 2 3>;
defines how wcd device SoundWire ports are connected to SoundWire Master
port.
The downstream waipio-audio-overlay.dtsi says:
56 qcom,swr-port-mapping = <1 SWRM_TX1_CH1 0x1>,
57 <1 SWRM_TX1_CH2 0x2>,
58 <1 SWRM_TX1_CH3 0x4>, <1 SWRM_TX1_CH4 0x8>,
59 <2 SWRM_TX2_CH1 0x1>, <2 SWRM_TX2_CH2 0x2>,
60 <2 SWRM_TX2_CH3 0x4>, <2 SWRM_TX2_CH4 0x8>,
61 <3 SWRM_TX3_CH1 0x1>, <3 SWRM_TX3_CH2 0x2>,
62 <3 SWRM_TX3_CH3 0x4>, <3 SWRM_TX3_CH4 0x8>;
I just don't know what how to trim the port config properties - we
have there four entries, but channels are only three?
Where do these come from? The downstream:
asoc/waipio-port-config.h / lahaina-port-config.h
Do do not have port config for this SWR.
yes, that along with dts is the source for this information.
--srini
Eh, not sure anymore. My second headphone started to work without these
changes, so I have no clue.
Best regards,
Krzysztof
