Historically, CPU and Codec were implemented different, but now it is merged as Component. ALSA SoC is supporting suspend/resume at DAI and Component level. The method is like below. 1) Suspend/Resume all CPU DAI if bus-control was 0 2) Suspend/Resume all Component 3) Suspend/Resume all CPU DAI if bus-control was 1 Historically 2) was Codec special operation. Because CPU and Codec were merged into Component, CPU suspend/resume has 3 chance to suspend(= 1/2/3), but Codec suspend/resume has 1 chance (= 2). Here, DAI side suspend/resume is caring bus-control, but no driver which is supporting suspend/resume is setting bus-control. This means 3) was never used. Here, used parameter for suspend/resume component->dev and dai->dev are same pointer. For that reason, we can merge DAI and Component suspend/resume. One note is that we should use 2), because it is caring BIAS level. This patch removes 1) and 3).
