On UCLB/KF, we intuitively think we want to handle these as "2 Sound
Cards":
card0,0: 1st sound of ULCB (SSI0 - ak4613)
card0,1: 2nd sound of ULCB (SSI2 - HDMI)
card1,0: 1st sound of KF (SSI3 - pcm3168a)
^ ^
However, because of ASoC Component vs. Card framework limitations, we
needed to handle this as "1 big Sound Card":
card0,0: 1st sound of ULCB/KF (SSI0 - ak4613)
card0,1: 2nd sound of ULCB/KF (SSI2 - HDMI)
card0,2: 3rd sound of ULCB/KF (SSI3 - pcm3168a)
^ ^
Now ASoC supports multi Component, which allows us to handle "2 Sound
Cards" such as "ULCB Sound Card" and "Kingfisher Sound Card", all
ULCB/KF Audio dtsi can be updated.
Note that this changes the Sound Card specification method from
userland, especially for Kingfisher Sound.
