[alsa-devel] [PATCH 0/3 take2] ASoC: TWL4030: Handsfree pop removal and mute
Hello,
Changes: REG_SW_SHADOW = 0x4A (instead of 0x50)
The following series fixes the HandsfreeL/R pop removal sequence: The pop removal is moved from the MUX_E to PGA_E DAPM control and also the sequence is modified to match with the sequence described in the TRM. Note, that the power-down sequence is not described in the TRM, it has been implemented in a way that it should make sense.
HandsetL/R mute: Since all bits are needed for the pop removal and they have to modified in a strict order/timing: I have added SW_SHADOW non HW register. This register at the moment only handles the HandsfreeL/R mute.

Move the HandsfreeL/R (IHFL/R) pop removal code from the DAPM_MUX_E to a more appropriate DAPM_PGA_E widget. Also fix the power-up sequence to match with the TRM. The power-down sequence is not described in the TRM, so do it in a way, which seams like the correct sequence.

Add DAPM switch for HeadsetL/R mute. Since all bits are are needed for the HFL/R pop removal to work the switch is using the SW_SHADOW no HW register for the HandsfreeL/R mute.

Applied all, thanks.
